Re: Fan control that is able to overcome bios?

Hello everyone, I hope someone will help me in my attempt.
I have a Toshiba protege z830, and what I am trying to accomplish is to have a better control over the fan speed.
_My motivations are the following:_
Intel implemented a new Thermal Daemon for Linux -https://01.org/linux-thermal-daemon
which is able to play with the processor and enable advanced cooling methods that can drastically decrease the temperature.
This means that this daemon is able to force the processor under a certain temperature (at the expenses of the speed of course).
In my tests I was able to keep the temperature below 70 degrees in any circumstances (also high cpu load!) !!
_Here is where the problems start:_
The BIOS of the laptop starts the fan and sets a high speed after a while that the cpu stays at that temperature (69+).
Which means that after 2 minutes that the processor stays at 69/70 (AND DOES NOT INCREASE - due to thermal daemon), the fan kicks in at high speed
The result is quite useless, as the temperature decreases of 2 degrees only, and the fan keeps running uselessly.
Moreover that temperature is not harmful at all, and as soon as the CPU works less, the temperature decrease to 62!
_This is the problem:_
The fan does not decrease the speed (stays at HIGH SPEED) until the temperature reaches back 57/58 degrees for a certain period of time.
Which is totally useless, as the only way to achieve that is to close all the applications and wait.
But the temperature that I have with normal usage is around 64! (always using thermal daemon).
So my operational ranges are between 62 and 70 degrees, which is not harmful for the cpu, and the fan should stay on at LOW speed, instead of being at HIGH speed.
What I want to accomplish is that the fan stays at LOW speed when the temperature touches 70 degrees!
Because when it touches 70 degrees the fan runs at HIGH speed all the time, until it goes back to 58/59 degrees, and it is very unlikely to go below 62 with normal usage.

WHAT I TRIED:
- I found the tool toshset ( http://schwieters.org/toshset/ ) that with the modified toshiba_acpi (in the same page) is able to control the fan!! Hurray!!
It is possible to increase, decrease and turn the fan of. So apparently the problem seems solved.
No! Basically the tool works only IF the fan didn't start automatically before! In fact, if the fan is started automatically by the BIOS (as described above, 70 degrees, HIGH SPEED)
it is not possible to decrease the fan speed anymore!! the command "toshset -fan 0" will not stop or decrease the fan!!
So, my question is, if there is the possibility to overwrite the BIOS settings of the ranges when the fan starts/stop,
or if it is possible to have the control of the fan (with toshset) even when the bios starts it.
WHAT ELSE I TRIED:
- I also tried to read the DSDT table and find some values that are related to fan control, in order to modify them, but I am not experienced with that and can not find anything.
I hope I made myself clear and someone is able to help me in some way
Thank you in advance!
ps. If you think this is not the right forum/section or there are other places where i can ask this question please let me know

  • 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.
    http://www.mediafire.com/file/njhz0icym2t/S10Fan.z​ip build 2009.05.23

    The first 4 values are the BIOS temperature thresholds, the latter 4 are new thresholds that we want to over ride with. To determine the BIOS temperature thresholds, use the 'test' option.

    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.

    A:
    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.

    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.

  • 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 :-)

  • Fan control in notebooks

    Hi all,
    I am using Arch Linux since a few months, right after purchasing my new laptop, a Dell Precision M3800. Anyway I am a linux user since many years. I like very much the control that arch give to the user in terms of configuration possibility. My question is relate to fan control in notebooks. Even though I noticed this issue in my laptop now, I think similar observation holds also for other notebooks and linux distros. For fan control I use the fancontrol utility. Once properly configured, there is a min temperature value below which the cpu fan is off (default is 20 °C, I increased up to 45 °C) and a max temperature value (default is 55 °C and I placed 65 °C) above which the fan is running at full speed. The reason for the temperature limit changes is to emulate windows behavior in terms of noise and thermal handling. With a room temperature in the order of 25 °C, I get right after login a cpu temperature of about 35 °C. Then the temperature increases even in idle conditions up to the limit of 45 °C and then it is stabilized by the cpu fan. Chaning the temperature between 35 °C and 45 °C simply changes the time interval I have to wait until the cpu fan switches on and cpu temperature stabilizes with low load. The point is the the stable thermal situation produces a continuous switching of the fan state, let's say the fan is on for a few seconds every minute. The reason is that the fan switches off right after the cpu temperature falls below the value for which it turns on. Wouldn't be better to define two different temperatures for switching on and off? Let's say, fan on when temperature reaches 45 °C and off when it falls below 40 °C. Is there a way to do that with fancontrol or same other tool?
    Thank you in advance.
    Bye,
    Luca

    OP, what you're describing is called (at least in HVAC circles) hysteresis.  You may be able to find some fan control scripts that support it (googling fan control + hysteresis), or just write one yourself.  You can also control this behavior to some extent by adjusting fancontrol's polling behavior (the "INTERVAL" setting), but that has risks. 
    I think implementing hysteresis is not a particularly useful endeavor because PC temperatures can change 30 degrees or more in a few seconds when under load, which is completely unlike, say, a home thermostat where temp changes are much more gradual over time.  Realistically, you should expect to always be running at least the CPU fan at some speed, and set your "turn off" temperature for it to room temperature.  You can set different temperature set points for different fans, so you can have the CPU fan turning off at a lower temp, but have other fans off until the temp gets much higher.

  • Fan Control Software

    I am trying to install the new version of SMC Fancontrol on my Intel Santa Rosa MBP. When i try installing it tells me that there can be no other fan control software running. My question is how do I turn off the existing software, and/or what am I doing wrong. I want to be able to turn up the fans whenever I need to do model and image rendering.
    Thanks a lot.

    It should do that automatically depending on how hot it gets.
    If it doesn't do this run a hardware test to see if there are fan or sensor problems.
    As for the SMC fancontrol problem, no clue, maybe email the developer.

  • Is anyone using SMC fan control on their late 2009 iMacs?

    I am very concerned about the heat from my iMac.
    I have a late 2009 27 inch model.
    I noticed a lot of posts of GPU and HD failures.
    I bought this iMac used through a certified Apple reseller and I can't afford any problems with this for awhile.
    Computer components do not Ike heat.
    And despite everything I have been reading in this forum aluminum can retain heat. Not simply vent all of it away from the back casing.
    Excessive heat is what shortens the life span of any components In a computer.
    Heat in a computer is the enemy!
    I do not care what I am getting for temp readings from my iMac.
    It's very, very warm and I don't like it and feel it will cause issues in the near future.
    I just bought this iMac three months ago and, at least for awhile due to personal health issues, I can't afford to repair a potential failure that might occur in the near future.
    I posted a similar thread not long ago but only got one response I was not happy or confident with.
    I want to know if anyone is running SMC Fan Controls on late 2009 iMac models and if it has helped and whether anyone had issues with it.
    I want my iMac to run cooler than it does now.
    I am in a living situation where I have limited means to cool the place I live. The room I am using has no air conditioning only a large ceiling fan and I am running a floor fan. I have a small fan blowing air behind the iMac's case to help with cooling it, also.
    Room temps can get into the high 80's.
    Also, if you are running SMC Fan Control on a 2009 iMac, could you give an idea what RPM setting you are using for the various fans.
    I am a freelance graphic designer, Illustrator, and audio/video guy.  Plus I have doing 3D CGI model work for the last few years. I run Photoshop. Final Cut and Blender quite often.
    Any real help with this issue would be greatly appreciated!
    ThanX.

    Even if I had one, I wouldn't run SMC Fan Control.  Apple has not released the limits of temperature for any of its Mac model interiors.  As such any temperature management is purely guesswork.  If you are having serious trouble maintaining an enivoronment suitable for computers, you probably should consider at minimum a window air conditioner unit.  http://www.apple.com/imac/specs.html are very particular about the outside environment.  If that is not able to be maintained, you seriously need to consider a different working environment.

  • MSI Z87-GD65 gaming fan control

    So i recently installed 2x 120mm noctua and 1x noctua 140mm fans in my system, they work great and i can control them no problem from the bios, but i recently noticed that my Noctua NH-D14 cpu cooler runs full speed all the time, from what i know the fans on the cooler are not pwm, but i would think you would be able to control the fans with voltage, but i cannot find anything to set that in the bios or anywhere else, is that true?

    yeah i connected the fans to the LNA (low noise adapters) for now, would still like to be able to control them, but atleast the annoying sound seems to have come from the fans spinning at full speed, will have to invest in a few pwm fans soon, but thanks

  • Afterburner - Fan Control of Lightning editions in SLI/Crossfire

    Hi guys,
    Any chance that MSI will address the issue of not being able to control the middle yellow fan (fan2) anytime? It's been more than a year, they keep selling Lightning editions but not supporting the fan control when used in SLI/Crossfire. It's not like there is only one card out that has this issue or that they will be stopping the Lightning-line.
    If anyone has a tool/workaround for this, please let me know.
    Thanks!

    I am not talking about the CPU fan. As I wrote above, the CPU fan control works.
    Its about the case fans. They run @ 100% all the time, the board doesnt seem to control the speed here.

  • 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.

  • Re: p67a gd65 b3 CPU fan control staying at 100% ?

    I hate to be reviving this thread, but it's already got evidence of my problem.
    Basically, Only 2 out of the 4 PWM controllers on the motherboard (P67a-GD65) allow for fan control. This was fine originally, when I only had two fans in my case, but when I upgraded to a third and plugged it in, it simply ran at 100% speed. Multiple scans in speedfan only found the CPU control and two PWMs. Looking in the BIOS it only saw two as well, even though the third fan was plugged in and running at 100%.
    My BIOS version is the one just before the ivy bridge update, so the 'improved system fan control' apparently didn't help.

    Quote from: Henry on 28-May-12, 04:09:10
    * There are only 2 PWM not 4, CPU fan & sys fan 1. The others are fan speed monitoring only and are not speed controlled.
    * Where do you get the idea that there is Ivy update for P67? The latest BIOS is 1.I:
    Update CPU Micro Code for Sandy Bridge C2 CPU
    The BIOS update page [http://www.msi.com/product/mb/P67A-GD65.html#/?div=BIOS];[Won't let me hyperlink] shows '- Update BIOS for IvyBridge 22nm CPU.' for BIOS v4. I nabbed version 1.19 because I have an i3-2100.
    The CPU fan is PWM controlled, but so are two of the SYSfans (I am able to control them through speedfan). I find it extremely hard to believe that the two other ones are for 'monitoring' only. You're telling me that they have 3 pins, two for voltage and one for monitoring, but they can't alter the voltage at all, so you'd have to put a controller between the pins and the fan? That completely erases the purpose of having the power coming from the motherboard. You could just get a fan controller that does the same thing, without having to screw around with the motherboard at all. Plus, speedfan doesn't even notice the PWM coming from either SYSFAN3 or SYSFAN4, if they are used for monitoring.
    This is the motherboard you're talking about, right? SYSFAN headers in red, and CPU in green.

  • 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)

  • 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:

    Thanks for being a part of the Apple Support Communities!
    Cheers,

  • 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?
