P6N Platinum Fan Control?

In my attempt to further silence my computer I bought a AC Freezer 7 Pro to replace the stock Intel HSF. After I installed it I started the computer and the fan was spinning at 2700rpm I was able to slow it down to 1700rpm(28db) using the Dualcorecenter utility but I wish to slow it down further down to about 1300rpm(20db).
-How do I lower the fan speed even more? (or manually lower the voltage to 9v ish)
-Can fan speeds be controlled under Bios, or am I stuck having to run Dualcorecenter all the time even though I don't get my desired fan speed.
-The stock intel fan throttled up and down according to temperature. Is the AC not capable of doing that?
So far I'm not satisfied with the AC at all. At 1700rpm the AC is just as loud as my stock intel hsf which ran at 2100, and my idle temps are only down about 1 degree celcius. (Just my $.02/buyer beware)

Under the hardware monitor under bios I can only set the "smart cpu target" which doesn't do me any good. I was actually able to lower the fan speed down to 1100 minimum using the speedfan program, but I still find it kind of annoying because I have to leave it on and the fan doesn't throttle according to temperature 
My heatsink is actually well seated and installed but the temps at idle dont change no matter how fast the fan is running? My e6600 is stock and at 1300rpm it runs at 30c idle/47c load(orthos). At 2700rpm it runs 29c idle/ 45c load. Besides the fact that it is quiet, the temps are pretty much identical to my old Stock intel hsf running at 2100rpm. I guess I can't complain as I got it for 29 USD shipped. Perhaps your great results are due to your cpu being overclocked. What are your exact temperatures
I have another question along with my previous three. Is the P6N unable to power the hard drives down during inactivity? I set the hard drives to power down after 45 minutes of idleness but none of them do. On my other vista machines the hard drives power down just fine. Thanks

  • P35 Platinum Fan control

    how to control the speed of the sys fans? with Dual Core Center it is impossible, how to make?

    What?.....this is just mindblowingly annoying.
    All boards I have owned for the last 8 years have been able to control fan speeds. I didn't even consider the possibility that that this essential feature could be lacking when I bought the P35 Platinum
    I was going to recommend this board to a friend, but without software fan control the board is almost useless in my opinion.
    Please never make a board in this way again...ever.

  • K8N Neo4 Platinum - Fan control missing?

    Good evening.
    I've recently assembled an Athlon 64 3000 (Venice) / Neo4 Platinum system, and unfortunatly I am not able to control the speed of any fan connected to the motherboard. Also disappointing is the fact that four fans are connected, but only three show in Speedfan.
    My CPU cooler is Thermaltake's Venus 12, so it's not MB-controlable.
    My Enermax 120mm fan connects using the usual 3-wire connection, and has an RPM knob integrated. It doesn't seem to respond to Speedfan no matter what the state of the knob is.
    Last but not least is the noisy chipset fan, which shows but also doesn't respond to Speedfan.
    There's also a 92mm Enermax fan which is connected the same way as the 120mm one, but doesn't show.
    I've only found two BIOS settings that were said to be relevant - Cool'n'Quiet and CPU Fan Target. Both had no effect. I did no find a NB Fan Target setting that some people reported having.
    CoreCenter seems uselss. It doesn't change anything regarding the chipset fan, and I didn't find any "Temp Alarm" setting for the chipset, that was also mentioned here at some time. Tried uninstalling it as well (probably with a restart, I don't remember), but it doesn't seem to have had an impact on the fan control issue.
    So essentialy, what I've got are four fans connected, three of those showing, two of these that can theoretically be adjusted through software, one that's too damn noisy at more than 7500 RPM, and zero that I can actually through software.
    And no, a Zalman Fanmate is not a solution after I've invested in this top-of-the-line MB. I expect to get what I've paid for.
    Is there a solution to this problem, once and for all?

    To get to the CoreCenter Temp alarms, you have to expand the right 'wing' (click little arrow); but this only sets temperature below which an alarm will sound: it has no effect on fan speed itself.
    But indeed, nothing on CoreCenter seems to affect NB fan.
    The manual itself only mentions that CPUFAN1 supports fan control. 
    [Will eventually apply myself hardware solution for nb fan, either single resistor, as described elsewhere on this board, or with rheostat; if i can find a store where to buy fanmate2, that would be better (shipping/handling from net order would cost more than the darn thing!).]
    @Flow: my case fan, connected to SFAN1, does show in Speedfan, even without CoreCenter lauchned (I removed it from StarUp list).
    (However, i still have the AMD PowerNow! Technology Service, ie GemServ, enabled and started)

  • P45 Platinum fan control issue!

    Ok i received a new MSI P45 Platinum board after my last one gave me nothing but problems and fried one of my Radeon Crossfire cards 
    Anyway the new one seems to be fine except one of my case fans seems sounds like it's spinning at full speed! I have case fans plugged into headers 1, 2 and 3 on the board and fans 1 and 2 can be controlled via the bios whilst fan 3 cannot! HWMonitor reports the correct fan speeds for 1 and 2 (running at 75%) and it tells me fan 3 is running at 50% but it's actually running faster and louder than the other 2!! With my old (faulty) P45 Platinum board the 3rd fan was quiet, but now it's very loud and i don't know why? I have the latest 1.6 bios installed as i did on my old board.
    Can anyone explain what is happening? Cheers 

    I installed the latest MSI Dual Core center and now it's telling me system fan 2 RPM is too low! (keeps flashing)
    CPU Fan =  around 1700 rpm
    SYS Fan 1 = around 1200 rpm (set to 75% in bios)
    SYS Fan 2 = around 700 rpm (set to 75% in bios)
    I'm not happy with this board... My last P45 Platinum had memory/CPU/PCI-E voltage issues but the fan speeds were perfect! And now this replacement motherboard has ok voltages but the fan speeds are screwed! Both boards are the same revision using the same bios and had the same system config.
    HWMonitor is still reporting fan 3 at 50% although it's literally screaming! Can someone please give me any suggestions as to whats wrong? Also does anyone have the latest beta bios (v1.7b10 i think). Cheers 

  • New P6N Platinum acting wierd...

    What's up guys.  My dad's computer at his office has been giving him problems like locking up, sluggish performance even after a reformat, etc so he gave me $1200 to build him a new machine that will last him "a long time". hahah
    So I've put together a pretty decent Core2Duo machine.  Here are the specs
    E6400
    P6N Platinum
    1 gig of Gskill DDR2 800
    This stick
    http://www.newegg.com/Product/Product.asp?Item=N82E16820231085
    A corsair 520 watt PSU
    Generic PCIE video card
    75 gig Raptor HDD (I'm going to use his existing HDD as supplimental storage)
    Samsung DVD writer
    I put it together, the system loaded windows XP fine, I installed the motherboard's monitoring software that Dual Core center thing, video drivers, Ntune software (which I now know is useless) and then proceeded to install office, some anti spyware apps, antivirus software, etc...
    That's all well and good but here's where trouble started up.
    During the software install, the Dual core center that was monitoring the fan speeds and cpu temp flashed at me saying one of the case fans wasn't spinning. I opened the side panel and both case fans were spinning fine.  (X_<)
    I disabled that montior and continue installing stuff.   A minute or two later, the other one goes red saying the 2nd case fan wasn't spinning.  I still had the side off and could clearly see all connected fans still spinning.     I disabled that one thinking it was the last I'd hear.
    I have an E6600 and another P6N platinum and 2 gigs of patriot DDR2 1066 ram coming today for my own system upgrade and I had already bought an EVGA 7600GT video card to use temporarily until the DX10 cards start dropping in price.
    Anyways, I wanted to see what sort of benchmarks the unclocked system could spit out so I shutdown, popped the 7600 in, rebooted, re-installed the latest Nvidia drivers and installed FEAR.
    I ran fear and it froze up during one of the pregame splash screens.  I held down the power button to reboot it and when I turned it back on, the system physically came on but there was no post and the monitor stayed in standby mode.  No beeps or anything.  All 4 little LED's on the Dbracket thing were lit up green.
    Thinking mabey something was up with the video card I shutdown and put the old card back in.  Same thing with this one now.  No power to the monitor, no beep, no post, nothing.
    So at this point, I start going through the usual suspects.  I tried booting with the ram in a different slot each time and still nothing, I unplugged the floppy and cdrom ide cables, nothing.  I unplugged the hard drive, pulled the Cmos battery, pressed the little clear CMOS button, etc... nothing.  I even went so far as to pull the video card itself and still no warning beeps or anything.
    At this point, I was thinking it could be the ram stick was bad or the CPU was bad or even the motherboard itself.  I was thinking mabey the mobo due to the previous warnings about the fan speed.
    In one last desparate attempt, I put the generic video card back in, hooked up everything but the floppy and put the memory back in the original green slot 1 and took it into the kitchen to my work space and plugged it in and turned it on and lo and behold, it beeped at me and the Dbracket LED's indicated that the floppy wasn't attached.  I hooked up a monitor using the VGA (rather than the DVI which was in my computer room) and the windows loading screen was up.
    I shutdown, hooked the floppy back up and watched the led's on the Dbracket as it started up and they appeared to go through a sequence of checking everything as they all were flashing green to red and then all green and windows was up and running as normal.  At this point, I'm still holding my breath just waiting for it to lock back up and give me grief again but it never does.
    right now, I'm at work and it's sitting next to me and has been running stress tests for the last hour and a half without a hitch.  CPU temp is peaking at around 53*C.
    When I get back from lunch, I'm going to run memtest and spinrite 6 to make sure the HDD is good to go and after that image the hdd for backup purposes.
    I'm hesitant whether or not I should tell my dad that his machine is finished becuase I don't know what in the world went wrong last night.  In my experience, when something fails, it's not going to work again.  I haven't tried running fear again.  I actually uninstalled it as he'll never use that but I was wondering if you guys could offer any ideas on what went wrong?
    I'm going to image both this machine and his old machine before I wipe his old HDD and put it in this new one just in case something does go wrong again, I can just pop the old HDD in his old machine, load the image and minimize down time while whatever parts need to be replaced are out.
    Thanks for any suggestions or ideas!   

    I had already planned on that.  I don't know if it was one of those that caused the problem or what but I'd rather it not be there at all than lurking in the background.
    Memtest came up with no errors, stress tests passed fine (for now) and spinrite is about finished with zero hdd errors.

  • P6N Platinum - Power down on boot

    I am looking for help in building my P6N Platinum based system. I will boot to VGA Bios and then power itself down. I can see the Machine write the VGA BIOS to the screen before power down, and the last light set on the D-Bracket is VGA BIOS write to screen. Only problem here is that card works fine in other machines and is less than a week old as a factory replacement for a previous card. I doubt it is the source.
    I swapped out a P4N that fried the previous XFX card, so This is getting very frustrating. New motherboard, new PCIE VGA card, yet another set of problems.
    I've been a longtime user and system builder with MSI products, But I suspect that compared to some here, I am still very wet behind the ears.
    I have:
    P6N Platinum v1.0
    XFX 7600 PCIE SLI in x16 slot of course
    Corsair XMS2-5400 2x512, timing of 4-4-4-12; 675MHz. Supposedly 1.9v
    Ultra 600W power supply with 18a & 20a per rail. 8 Pin CPU plug & 24 Pin ATX. 4 Sata & 6 Standard Molex plugs
    I have tried everything on a cardboard box and in the case. Grounding is not an issue.
    Have tried multiple power supplies already. I still have Newegg's RMA period, but want to rule out my other parts first. I cannot get to Post ever, so flashing Bios is not an option. Have tried to reset Bios three times already.

    It's 10 seconds easy for dual core. And it would explain the cut outs, the CPU shutting down the cores when there's too much heat.
    I reinstalled the processor and heatsink, and the machine will post and I can get to Bios. But after about 1 minute, the screen goes blank. It does not matter if I try let the OS load or go to the Bios. After about 60sec the machine will lock up and the screen will go blank. The fans are still spinning, the machine is still on, and the amber and green MB LED's are still lit. But nothing will happen. Blank screen, regardless of what I do.
    I suspect the CPU fan is not going fast enough and perhaps is damaged. I have ordered a warranty replacement from Intel.
    My question is, I tried to turn the machine on about 5 times tonight and got the blank screen. I have stopped trying now, but is it possible any of the MB was damaged by this trying? I still have 20 days left to RMA to Newegg.
    Does anyone have any other ideas why this may be happening?

  • P6N Platinum Memory Sudden Death

    I've been running a P6N Platinum for 11 months with no problems. I have an E6600 slightly overclocked and (2) sticks of G.skill 2GBHZ memory. I was using the computer as normal and had some slight hesitations, it had been awhile (weeks) since I rebooted so I did so only to get a bootmgr missing screen, tried again same thing so I powered the computer down. When I turned it back on, nothing no video no post only running fans. I tried one stick of memory in slot 1 then the other still nothing. I called MSI and they said it sounded like the board. I bought another one and had it next dayed. Put it all together and had the same problem. Went to the local computer store and picked up a new power supply and memory came home put the memory in and all was well again. So my question is what would take out to sticks of memory at the same time? I have a Enermax Liberty 500W dual rail supply and the whole system is on an APC 1250 conditioning backup. Do you thing the old board is still good or should I send it back to MSI?
    Sorry, the original system is as follows.
    MSI P6N Platinum motherboard
    Intel E6600 CPU
    Scythe Infinity Cooler
    Enermax Liberty ELT500AWT PSU 28A@+3.3V 30A@+5V 22A@+12V1 22A@+12V2 .6A@-12V 3A@+5Vsb

    MSI NX8600GTS-T2D256-OC Video Card
    ATI Theatre 550 PCI TV Tuner
    (2) Seagate 320 GB 7200 RPM Serial ATA drive.
    Samsung SH-S203B DVD reader/writer
    Vista 32bit Ultimate.
    The new memory installed is.
    2GB kit (1GBx2), Ballistix 240-pin DIMM, DDR2 PC2-8500
    I didn't end up using the power supply I bought at the local store just the new Ballistix memory. I hate to try the new
    memory in the old board just in case there is a problem with the board that took out the memory. I could see one
    stick failing but two at once is kind of strange. The memory was set at 2.1V 4-4-4-12 2T.

    Well, I suppose testing the board again with your new components is the best chance to get a definate answer to this question.

    Provide full system specs, otherwise it is hard to answer this question.  Read the >>Posting Guide<< to get an idea of what details we need to know.
    You said you bought a new power supply.  Is that the Enermax Liberty PSU?  If not, what kind of power supply were you using before (brand, model, amperage limit on 5V, 3.3V and 12V rails)?

  • P6N Platinum OC - BIOS 1.5 1333max / 1.4 1480 max

    I have two P6n platinum boards - one with a 6750 and one with a 2140 and neither will go beyond 1480 Mhz FSB. I have tried every suggesstion I've seen in forum posts
    Hardware is 2 or 3 sata drives, nvidia 8800gts or 6800, xfi on one system
    1) up cpu voltage
    2) up nb voltage
    3) up vtt voltage
    4) disable eist (try 6, 7, 8 multipliers on 6750)
    5) disable c1e
    6) jump possible fsb hole from 1500-1600 and try beyond
    7) slow down memory
    8) disable all spread spectrum
    9) try linked & unlinked settings
    10) try several BIOS revs
    However, no matter what I do, I can't get to 1500 or greater Mhhz on either system and the symptom is always a non-post (black screen after CMOS save or power restart). I would normally expect to get past the post screen or into windows with OC problems, but these boards NEVER post after the 2960mhz limit. Insert key will get me back most times, but sometimes I have to use the CMOS reset button
    The 1.5 BIOS is a complete failure - just setting the frequency control to auto and leaving it at system defaults (1333/800) prevents a post even though auto works fine (I didn't try the 2140 board). 1.4 and the 1.t beta version get me to 1480
    One other thing - changing FSB in software does not work either. DualCorecenter does not allow changes after 350mhz (it resets automatically) and other programs like ntune just lock up immediately
    My 6750 has a high-end scythe infinity and the other is a stock cooler and both report incredibly cool temps
    Any recomendations to get past my max point?
     TIA

  • In my macbook pro 15 inch mid 2012 model, my cpu and gpu will get very hot, when gaming or rendering sometimes over 200F. The fans only spin at max about 2900 rpm, when their max is 6400. I downloaded a fan control app, but how can i fix it?

    Hi rhaughan,
    I see that you have concerns about your operating temperature of your computer while using resource-heavy applications such as gaming applications. I have an article that will address some of the concerns you have mentioned:
    Mac notebooks: Operating temperature - Apple Support
    http://support.apple.com/en-is/HT201640
    While there are third-party utilities that measure the temperature of a notebook computer, it is important to understand that these utilities are not measuring the external case temperature. The actual case temperature is much lower. Never use third-party applications to diagnose possible hardware issues—instead, contact Apple or go to an Apple Retail Store or Apple Authorized Service Provider.
    You should also see this article for even further information about your fans:

  • User-devel​oped Fan Control for the S10(e)

    Hello and welcome.
    When you've searched the internet and found this thread, it's possible that you are an owner of a Lenovo Ideapad S10 or S10e which has a little problem with the behaviour and/or the noise of the fan. In this post you will get all the informations you need to handle this problem for yourself. It should also be the same on every S9/S9e.
    Just a few comments before we begin:
    This is not an official support or solution by Lenovo.
    We are just normal users as you are, but we get rid of the fan and wanted to find a way to handle it. So if you want to try anything of the methods described here you have to know that you'll do all this only at your own risk. We are not responsible for any damages of your device. You should only use these methods if you know what you are doing.
    Please note that this thread is only for discussing, improving, trouble shooting and perhaps extending the fan control utilities. Any general complaints about the fan problem itself should be placed in the original thread right here: http://forums.lenovo.com/lnv/board/message?board.i​d=IdeaPad_Netbook&thread.id=795. It already has 80+ pages (the link goes to the first page) and it is better to exclude all the fan control stuff because there it's very difficult to keep an overview.
    Here you may post all of your questions, ideas/brainstorming, concerns, thanks and so on and you are really invited to participate and be an active member. 
    In this first part of this post I'm going to summarize all information about using a fan control utility. For any newbie it will be enough to read this post to get all necessary information. The second part does the same for developement of fan control utilities as we still have no known or working fan control utility for Linux, Mac OS X and other OSs I've forgotten - for now.
    For getting started you need a S10 or S10e with an up-to-date BIOS. For the S10 it's the 90 67, for the S10e the 66.
    The battery issue
    Under very specific circumstances - that we haven't figured out yet - it might happen that your Lenovo S9/10(e) no longer detects the battery while using S10FanControl or S10Fan. It might occur after 2 minutes, it might occur after 2 months, it might never occur. It does not occur using Notebook Hardware Control.
    It can be solved by removing the battery, waiting 10 seconds and put it back in. Then the battery is re-initialized and the detection works again.
    S10FanControl - Windows
    The first utility is S10FanControl created by user dresslerc. The current version is 1.0.0.1, available here: http://www.mediafire.com/file/yd5xmnrnijf/S10FanCt​rl1.0.0.1.zip. After you've downloaded it you just have to extract it and start the .EXE in the "Release" folder. Here are the notes and the description dresslerc posted right here:
    Everyone,
    I've uploaded a version which everyone can use to test with.  Remember this is still a TEST version although I think it works for the most part.  It should work both on the S10/S10e.
    Please install the .NET Framework 2.0 or later first.
    Then click here to download the exe:  http://www.mediafire.com/?jlg2enkjdxn
    Once downloaded, extract the files and hit hte S10FanCtrl.Exe.  Once this program launches you should be able to control the fan.  Keep in mind that if you lower the fan speed then it'll take upto 30 seconds before the S10 registers the change, so be patient.
    I've only tested this on the latest BIOS 59.  I am sure it will work on the 57 as well but the individual speeds might not work properly on that version.  Please try it out and report back.
    The only issue that I heard so far is that occasionally the fan will kick in regardless if in Manual/Smart Mode.  Also the temp it shows may not be accurate.  If you find any other issues please let me know what they are so I can attempt to fix them.
    Once we have all the kinks worked out then I will release the source. 
    Heres a quick Video:  http://www.youtube.com/watch?v=_PKl70ZgmFg 
    REMEMBER: USE PROGRAM AT YOUR OWN RISK!!! I AM NOT RESPONSIBLE FOR ANY DAMAGES THIS PROGRAM MIGHT CAUSE.
    Application Use:
    BIOS Controlled - Fan is controlled by the BIOS
    Smart Mode - Fan is controlled based on the conifguration in the options.  You can set the threshold here at what temp you want the fan to kick in...
    Manual - Fan is controlled manually by the slider.
    If you want to have the program startup automatically, then place a shortcut of the app in the PROGRAM FILES -> STARTUP folder.  Then you may want to go to the options and make the application minimize at startup.
    Edit:
    It seems there are some issues with the app and the S10e or previous BIOS versions.  Will post a fix asap.
    The source code for S10FanControl is available here: http://www.mediafire.com/?sharekey=7a3fb99d33817c0​8c2b435915e8821d7e04e75f6e8ebb871, written in Visual Basic .NET 2008.
    S10Fan - Windows
    The second utility is a tool written by user slash:
    Hi guys,
    Well it looks like Lenovo dropped this matter after all. Anyway, I have here another fan controller to add to the bunch. I have been using it for some time now without any problems. It is for both S10 and S10e.
    What the program does is basically the same as others. The S10's fan speed is controlled according to the ACPI thermal zone temperature. By over writing the values which resides at offset 50h of the EC register at an appropriate timing, the ACPI thermal zone temperature is over ridden. The program is written in C and uses WinIo created by Sysinternals. The GUI version is available now.
    It should be noted that the fan speed temperature thresholds differs with BIOS version. For 14CN67WW and 14CW90WW  the fan changes speed at temperatures 60c, 65c, 70c, and 80c. Furthermore, the BIOS will automatically shutdown the S10 if the temperature reaches 90c.
    The program has a fail safe mechanism that automatically disables itself if the actual ACPI thermal zone temperature goes above 85c. This allows the BIOS to regain control and the fan will work as intended by Lenovo. If the temperature drops below 85c the program will take over control again.
    To run the program, you will need administrative privileges.
    Known working BIOS versions:  14cn58ww,  14cn60ww, 14cn67ww, 14cn90ww
    The program will work with any BIOS version as long as the BIOS uses the 50h EC register readouts to control the fan.
    build 2009.05.24
    Higher priorities for EC commands.
    Usage: The program will run in the system tray. Double click or right click and use the menu to open the program. To determine the BIOS temperature thresholds, use the 'Setup' button. To run at boot time, place a short cut in the startup folder.

    Notebook Hardware Control - Windows
    The third utility is a profile for Notebook Hardware Control. I've adapted it from a profile for the Lenovo N500 which I've found here: http://nhc.yourcopy.de/overview/. With the manual for creating the profiles that can be found here: http://www.notebook-treff.de/board/database/hilfsp​rogramme-f%C3%BCr-nhc/92-how-to-create-an-acpi-fil​... I was able to change the ACPI commands to work on the S10(e).
    Installation and setup is divided in two steps. The program Notebook Hardware Control (NHC) is available at http://www.pbus-167.com/. Install the program, but do not start it for now. Then you need my NHCConfig utility, available here: http://forum.eeepcnews.de/download/file.php?id=147​6. It detects your model number and BIOS-version via WMI and writes a proper S10(e) profile to the NHC acpi directory. The GUI is German if you have a German Windows and English if not. Additional languages can be added.
    After you've extracted the ZIP-file you have to start the nhcc.exe (requires .NET Framework 2.0). At first a message appears that you use the program at your own risk. Then you can choose if you want to apply your own settings (experts) or if you just want the program to run with my defaults (newbies). In the settings window you can see your system details on the left, you can set up your thresholds in the middle and you can set the fan speed you want on the right. Then click on execute. 
    Now start NHC. Go to the "Settings" tab and click on "Show all NHC options and settings". Then a few more tabs appear. Go to the "ACPI" tab and check if the "ACPI Control System" is running (if everything works, the message "ACPI Control System running" will appear, otherwise it says "ACPI control system is not yet configured for this system"). Now click on "Show ACPI Control System details".
    Here you can change the temperature values the fan control depends on (the settings from NHCC are the default values). On the bottom of the window you can see the "Current CPU temperature". That is the value you have to deal with. In general it has a value of around 60°C. In the middle you can see four user editable temperature values. You can leave the values as they are if everything works. The on/off values are responsible for the temperatures at which the fan starts running and stops again after cooling the device. The level values are responsible for the fan speed, for example you can set the off_level higher to let the fan run all the time at the lowest level, if the values do not fit for your device or whatever.
    You can switch between NHC and BIOS control by disabling or enabling the "ACPI Control System" or by closing NHC.
    Q:
    A:
    With every utility it is possible that it takes some time until you see an effect after you've started the program. Any failure of the programs should be no big problem because the only thing that should happen is that the BIOS controls the fan. Another issue that might occur due to the way the fan is controlled is that the fan may start running for a very short time and it looks like the fan control has lost control. The fan should stop immediately or at least after a few seconds.
    Keep in mind that running the S10(e) with a fan control means that the S10(e) has to deal with higher temperatures. That could mean that the device will not last for 10 years but only 9 years (who uses a netbook so long...?). In every case you need a tool for monitoring your cpu temperature. We know that especially Core Temp 0.99.5 and Real Temp 3.00 do a very good job. That is important because the temperature values you need to set up the fan control are different from the values reported by the cpu sensor, they are between 15°C and 20°C higher. A normal temperature reported by the monitoring should be around 40°C, with the NHC default values the fan starts running at 52°C and stops at 38°C.

    END using fan control
    BEGINNING developing fan control
    Controlling the S10(e)'s fan is a litte bit difficult because it looks like there is no way to control it directly. But it is possible to manipulate the temperature the BIOS fan control depends on. As long as the built-in fan control thinks that the cpu is cool enough the fan stays off. And that is exactly the point where we can attack.
    The fan control depends on a field called RTMP in the memory of the embedded controller. It can be accessed via "_SB.PCI0.LPCB.EC0.ERAM", the offset of RTMP is 0x50 (hex) or 80 (dec). It is a direct I/O read/write. The complete NHC command for reading the value is: ACPI.FIELD.ReadByOffset("_SB.PCI0.LPCB.EC0.ERAM", ref value, 0x50, 8) with "value" as the variable which gets the value.
    What program logic do you need? You need a timer or something else that conducts an always-refresh cycle. It sounds very easy: You read the value, manipulate it and write it back. And it is that easy, you just have to keep some things in mind.
    This refresh has to be done very often. The procedure must be very thin and quick. Also the bus that is used to communicate with the EC is a problem, but since the S10e BIOS 66 it became a minor problem for me because it looks like the built-in fan control now depends on some kind of average value over the last few seconds and it doesn't really matter if one write-cycle is failing.
    The read-event must be placed before the write-event. Otherwise you just read your manipulated value. The field is filled by the system regularly, so you just have to test if the read_value is different from the written_value, then you know that the field was filled with a "fresh" value. Like "if read_temperatue <> written_temperature then real_cpu_temperature = read_temperature else do nothing".
    About the values you have to write back... you will have to test and play a bit. My experience is that you can select three fan levels, starting at 59°, 62° and 70° - at least with the NHC profile and my S10e it's like that. It's some trial 'n' error. My fan stays off at < 59°, but you should select a very low value for fan_off like 30°. In my opinion it switches off much faster the lower the written value is. But it's just a feeling, I haven't measured it.

    Perhaps some users from countries with other languages than German and English can add tags for "fan", "control" and "noise".

    Great opening post Carsten!
    The latest bios:
    http://www-307.ibm.com/pc/support/site.wss/documen​t.do?sitestyle=lenovo&lndocid=MIGR-71252 (BIOS 66)
    The FSB can be reduced from 133MHz to 100MHz using SetFSB, this also reduces the heat:
    http://www13.plala.or.jp/setfsb/
    clockgen = SLG8SP513V
    If you add a shortcut to the startup folder the program will start at startup. Under properties you can change the target to:
    "C:\Program Files\SetFSB\setfsb.exe" -s100 -b1 -cg[SLG8SP513V] -w20
    So it starts with a FSB of 100Mhz, in the background, with the right clock generator, after 20 seconds.

  • Does using a program like fan control damage my mbp?

    I heard good things about this program so I downloaded it and it cools off the machine wonderfully. However, I was wondering if it caused damage to the machine as the fans are running at about 3 times what they ran before? Does anyone know anything about this? Thanks.

    I would hazard a guess that if it did have anything to do with the failure of the hardware in any way, the manufacturer would void your warranty. Any repair needed would be chargeable.
    Mac OS X, Boot Camp and the EFI firmware all have system settings created by the manufacturer. Using a program which alters their recommended settings or changes the behaviour of hardware devices within the machine, goes against the terms of the warranty.
    I would ask Apple about Fan Control and get them to confirm that any damage which may be caused (or may not be caused) by a third party program willl not void your warranty.
    In some respects, it's like overclocking a PC. Whilst it may be more beneficial to the system and provide better performance, the maufacturer of the computer can not be expected to repair something which has been damaged by the end user 'tweaking' settings to get better performance.
    In the case of Fan Control, I have not used it so can not refer to the licence terms, the liability of possible damage done to the machine by using this program will either be at the end users own responsibility or the manufacturer of the software. This should be checked prior to installing and using the program.
    I would suggest any program which alters the running of the machine will invalidate your warranty in the event of hardware failure.

  • 848P Neo-LS Fan Control

    As said - no control of the damn fans (Case/CPU) on my 848P Neo-LS. On the CoreCenter the button lits up on mouseover, but when pressed, nothin' happens (as said in manual, press to toggle user/auto modes for fan control).
    Also CoreCenter doesn't show the Case fan's speed, but Northbridge (NB fan) fan's speed, which is obviously 0. Also NB temp is N/A. Also +12V is N/A. Also the FSB stays always at 101 Mhz, not 100. No overclocking done.
    Today upgraded the CoreCenter to the most recent vers (1.7.0.0.), and the button doesn't lit up anymore...?
    When I installed SpeedFan 4.17, it allows me to control the Case fan's speed from 2300 - 2700, but nothing more. Interesting.
    CPU - Celeron 2.0
    RAM - 256 MB Kingston
    CPU Fan - OEM intel fan A80856-003
    Case Fan - MJ 802512
    Both fans with speed sensors, of course.
    Should I update the bios?
    Help somebody!

    To be sure I opened the case and stopped the fans by hand (I don't use the corecenter prg - piece of crap), to see that i have mistaken both fans (in SpeedFan prg). The one who varies by 400 rpm is the Cpu fan.
    Doooh.
    The bios health screen doesn't show +12V at all - just aint there...
    The MSI tech support sez - flash the bios, and if anything doesnt change, the CoreCell chip has gone (faulty, whatever).
    Flashed the bios (1.0 - 1.9 now). No changes.

  • Enabling system fan control on lenovo s30

    Hi there, i am familiar with the BIOS setup for fan control, except, i do not know how to load a "user profile" vs factory default. Does S30 even support user fan control, my d20 would allow me to select several presets, however, the s30 bios only allows two options one of them being user preset? How do i load this preset (i want the fans running at higher rpm for additional cooling). Any insight is appreciated.

    There are a few differences in the fan control design between 20 series and 30 series.  In 20 series, you're correct that there were a couple of selectable presets available.  For 30 series, we took a different approach where the fan speed control was set to a standard profile for all users.  We did, however, have the ability for our BIOS team to create unique fan tables that would be meant for specific customer environments.  The only way to use one of these custom tables would be to work directly with our BIOS team as each table would need to be manually created.  So custom tables are not supported for general field use.  
    We chose that route on 30 series because a very large majority of our customers never changed the default fan settings (the thermals on 20 series were so good they rarely had a reason to do so).  
    Is there a specific reason you want to change the fan control, or is this just a tinkering-type question?

  • IdeaPad S12 - fan control

    hello,
    I'm the proud owner of a S12.
    I've got the same problem as a lot of people with the S10: the loud fan. It's just running after a while and not switching off again. Is there anybody out there who could fix this problem with a little prog or using nhc as some did with the S10.
    The programs from this forum for the S10 don't work on the S12.
    Thanx a lot!!!

    Hi, sorry no good news ...due S12 differences ... its not possible to control fan via  NHC/NHC control for S10 got to work for the S12 ....as in this post Carsten says
    No S12 Fan Control  and other programs didnt work at all...

  • Custom Hardware Fan Control - problem if speed pin not connected?

    Hi There,
    I am planing to install a hardware fan control (poti) to my MacPro 1.1 rear fan. (because I have a defective northbridge temperature sensor and the fan is running at maximum speed... so i thought of slowing it down with a fan control for the pci slots)
    I read that the pinning of the Fan is: Gnd, 12V, Speed, Control Pin (analog Voltage)
    So when i would attach a fan control (just a poti) between some +5v and the Control Pin I think I should be able to control the fan manualy - am i right?
    But then the speed signal is not the speed the mac pro fan control software think of... so would it be a problem e.g. if i disconnect the speed pin from the mainboard fan connector?
    what would happen then? is the mac pro powering up the other fans for some kind of failsafe?
    Or have you other suggestions how I can lower the speed of the rear fan manually?
    thanks in advance,
    Stefan

    Take a look at the project some have undertaken to go with water block.
    Send the motherboard in to have a 'skilled' electrician? repair the board perhaps.
    4 fans, 3 under the control of SMCFAnControl utility. Maybe disable the one fan and make up for it with your own fan and running the others efficiently.
    There are also VGA copper coolers.
    FBDIMMs bleed heat: maybe the RAM fan cooler kit in there to deal with large source of heat. New higher density DIMMs are better made and few DIMMs = less heat even if 4GB.
    Use ice packs, dry ice and liquid nitrogen to super cool :-)
