Fan controller

Why does´t my fan speed depend on the temperature?? 2800rpm @ 40C and 2800rpm @ 70C
I´ve got a 915gm-fr with P4 530 cpu and a Arctic Cooling Freezer 7 fan (4pin)

According to the manual the CPU_FAN2 connector is to be used for the cpu fan. You then need to run a utility like CoreCenter to control the fan speed.
I prefer SpeedFan to CoreCenter, but you will have to find out how to configure it on your own. The link in my signature could get you started.

  • CPU Fan controller / Noisy CPU Fan

    Hi All.
    I have the GD65 and the FX 8120 and the CPU fan is a bit noise( ~5750 RPM ).
    Is there a smart/PWM CPU fan controller in the bios ?
    The end goal is to only have the CPU fan get noisy when under load and not all the time.
    Thanks in advance.

    i.e. set you target temp to 40C and a minimum fan speed of 25%. That means your fan will run at 25% of its max rated speed until the CPU temp is at 40C, at which stage it will start spinning up to higher speeds.
    The bios is the new fancy GUI and mouse one.
    I found a a setting that seams to match your description: "Main->Hardware Monitor->CPU smart fan controller" and that then showed a setting called "CPU min.fan speed()"(looks like a function call to me).
    I set the "CPU smart fan target" to 40C and the "CPU mun.fan speed()" to 50%.
    So now would that mean that the CPU fan will spin at a minimum of 50% at 40C and slower when when less then 40C ?

  • Fan controller question

    This is probably a quick and stupid question, I am running some vantec 80mm tornadoes which are a bit loud. Well actually if you can imagine a boeing 737's engines powering up you know how load these fans are. Seriously though they are about 71 Dcb. So I would like to control their rpm depending on my needs. My question is, can the K7N2-ILSR only support two fans directly off the motherboard (the nb fan and cpu). And I have to buy a fan controller right? Or is there another way I am not aware of.
    Im sure some people will tell me I shouldnt have bought these fans, but they really do push a lot of air,
    Thanks everyone  

    I have a CoolerMaster Aerogate II control box.
    It looks neat, it monitors temperatures of 4 devices and you can run your fans to it and control the speeds with a dial, as longs as the fan supports speed control.
    The temps are accurate, while I'm in the bios screen I saw that the Aerogate was reporting the exact same CPU temperature as the bios was, but Aerogate was refreshing faster.  (it's a real time).  I have the Aerogate's diode run underneath the heatsink, right next to the CPU die.
    The Aerogate has a LED screen that's blue, and the devices are selected through "channel switches."
    The Aerogate cost 45 dollars (USD).
    It's my new favorite toy.

  • MSI fan controller and sli ?

    I have 2 x MSI GTX980 Gaming SLI and I noticed that the fan controller gave me the status of the second card not the first one. How to get the info from the first card ? 

    In Fan Control it will only show one GPU temperature for your display video card. If you want both GPU temperature I think you can try download Afterburner. It will show both GPU temp.

  • MSI Fan controller software for SLI ?

    Is MSI think of make compatible their MSI fan controller ? 

    Quote from: TZBC on 04-February-15, 08:49:44
    You mean "VGA FAN Control utility"?
    it should be compatible with SLI, but system will recognize them as one graphics card, so you set the fan speed, two of the SLI card will response the same speed.
    The status of the card is from the second one and nothing about the first one. it will be good to have a drop down menu to switch between cards.

  • GTX980 SLI fan vs fan controller info.

    I received my GTX980 Gaming 4G (2). I use the fan controller software but i wonder how to adjust the fan speed of each individually when i am in SLI ? So far so good. The cards gave me more performance then the EVGA GTX780TI. The cooling are better compare to EVGA cooling solution. A Happy guy   
    note : I pull off that sticker on the fan upward and peoples have to be careful of not pushing on the fan when you peel off that sticker or you will break the fan mechanic.

    I've also just received my GTX980 gaming 4G (also in SLI). Freaking amazing!!
    The only problem that I have with one of my cards is the MOSFT fan on that card does not shutdown when all the other do. PSTLOUIS, does all your fans turn off, once you have booted into windows?
    NOTE: I have tested the card in which both fans turn off and it works on it's own. When I test the second card, I've noticed that the fans still doesn't shut/turn off.

  • Need tech help for MSI VGA Fan controller for gtx 780 SLI

    Just curios how to get the VGA Fan controller to work on the 2nd card that's in SLI? I can get the 2 fans to run 100% with afterburner but the middle one wont on the 2nd card? Thanks!

    I have the same problem. 
    On GTX 780 Lightning, Afterburner will control both cards 90mm fans.  Afterburner will not control the middle fan (fan 2).
    The MSI fan controller will only control one card, not both.  I think there was a major oversight here.  They either weren't thinking anyone would SLi GTX 780 Lightning when they made the fan controller or its horribly broken.  In my case Rakunvar, my bottom card (PCI-E slot 5) is controlled while the top card (PCI-E slot 2) is ignored.
    I heard somewhere, they plan to fix Afterburner so it will correctly work with the 780 lightning.  It seems to me they put the MSI fan controller in the box with the GTX 780 Lightning because they must've known that the current beta Afterburner wouldn't control the middle fan. 

  • Default fan controller, or one of the many daemons for the task?

    Hi folks,
    I have recently undervolted my laptop using the instructions in the PHC Archwiki and it is running nice and stable. I was thinking about looking at the fan speeds to further increase the efficiency of my system the system and reduce noise. I am using an Acer Aspire 5920G.
    What I am looking for is more adaptive fan settings that are more in tune with the temps of the system, while keeping the fan noise to a minimum. My fans currently come in settings that seem to be 'off', 'low' and 'full', when what I really need are more adaptive speeds, i.e. more steps. Is one of the fan control daemons a better option for my needs, or is my system firmware usually the best choice. Does anyone have any comment on laptop fan scaling?
    Cheers,
    Scott

    Hi there,
    I have the acpi-cpufreq module running which I configure through the power management setting in KDE. As I'm sure you know, it works the same way as the various cpufreq modules, but can powernowd be used to control the CPU frequency using the built in KDE tool? I always used to use powernowd when I was running Gnome, but only recently made the switch over to KDE 4.4.
    As for the fan speed. My laptop fan runs well enough and there is not really an issue with the fan per se because the laptop is pretty decent. My issue is really that the CPU temps seem to fluctuate. The fan seems right when under very low load (off) and when under very high load (full), it is in between where I have the issue. It seems to stay too low for too long, then jumps to full pelt when doing CPU intensive tasks, if there were more speed increments in between, this would resulting in an overall reduction in heat and noise. What I am really asking is, does the fan speed daemon provide this?
    Cheers,
    Scott

  • MSI HD5970 bios + fan controller unlocker

    My MSI HD5970 is working great and i am not planning to overclock it, but i would like to change the fan speed without starting/using MSI afterburner manual everytime. (It does not work on auto startup)
    Is there a new bios version i can flash or a way to unlock fan control ?
    The card is running 15C cooler with the fan set on 40%/70C
    All help is welcome.  

    Hi Mark.
    I got MSI Afterburner working now with auto startup on windows with fan control set, i forgot to set CCC ATI overdrive fan control on 25% it was set at 40%. ( My fault  )

  • MSI GT60 Fan Controller?

    I know there is a button to max out my fan but sometimes that's unnecessary. I was wondering if anyone was aware of a program where I could manually adjust the fan speeds for when things get a little too warm. I notice sometimes the fan will adjust itself, however, sometimes it doesn't adjust nearly high enough. The max fan creates a lot of noise that I don't mind too much, but it'd be nice to keep it quiet sometimes like when watching netflix.
    Appreciate any help, Thanks.

    Hi Clerity
    MSI designs 1 single button named "Cooler Boost" to max the fan speed, it is great design when system under heavy loading, if you think it is too noisy after enable the " Cooler Boost" , the default cooling system will detect the system loading and adjust fan speed automatically, don't worry about the heat !! good luck @@

  • Gaming Z97 5 Fan controller issue

    I have a Gaming Z97 5 motherboard. I just got 3 120MM PWM fans. They all work great except one. Its on Sys Fan header 2. It will not start. It tries to, you can see it try to spin but it wouldn't. If I flick it with my finger then it spins up. What would cause this? Also in the bios if I set the fans to always be full speed it does the same thing, will not start. I tried this fan in another system and it works perfectly fine. What am I missing here? I am on the latest bios 1.6

    Did you try it on another header on the same board (not another system as you mentioned)?

  • GTX980 gaming afterburner vs msi fan controller.

    I noticed that the first fan are under the control of the custom fan profile from afterburner but the second one are under the control of the bios. Is there any way to have in afterburner the possibility to applied a custom fan profile for that second fan ?

    ^ Lol, then why MSI put this feature on these cards including 980 Gaming ? If their software, afterburner, doesnt have an update to fix this issue ?!
    Also, i know that one fan for 980 gaming is controlled by gpu temp, and the other fan by vrm temps.

  • Smart Fan Controller?

    I need a fan controling device for my 3 chassi fans that is as smart as SpeedFan where you can set trigger temps and control the speed both manually and automatically. I can't plug the three 12V chassi fans to my motherboard and let speedfan do the job right?
    So the device I'm looking for should have the following features:
    1. Should be able to change fan voltage from 5 to 12V
    2. Have at least 4 channels. One for vga fan, one for cpu fan, one for blow out chassi fan and one for the 2 inlet fans.
    3. Temp monitoring for all channels. Trigger temps that can change speed and shut down/turn on fans.
    4. Trigger temps must be changeable by user.
    Is there such a device on the market today or so I have to build one myself?
    Found this the other day http://www.coolermaster.com.br/index.php?LT=english&Language_s=6&url_place=product&p_serial=ALD-V02&other_title=+ALD-V02+Aerogate%20II
    but it's really a useless device since it wont let me change the factory set parameters

    This is new, does automatic control but the review does talk about changing setpoints.

  • 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

    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.

    Q:
    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.
