Fan control questions

Hi
I have a mid 2008 2.8Ghz iMac with the stock 320 Gb HD and 4 Gb ram. It runs fine but I am worried about how hot the case gets at times, in particular the top left corner. I have iStat widget installed too which shows what I think are reasonable temps most of the time, but sometimes even after just everyday use (browsing etc...) some of the temps seem high (power supply is presently at 75c). The fan speeds don't seem to increase much at all from the factory minimums. I know about smc fan control and iMac fan control, but I have a couple of questions before I decide to use them.
1. Do you think I need to be worried about this?
2. What damage could I cause by running the fans harder?
3. If I use these utilities to push the fans harder than Apple recommends, will I void my Apple Care?
Looking forward to your answers
Paul

An utility like smcFanControl only changes the minimum fan speed setting. You are still running the fans well below its maximum capability. So the change is to the low end of the speed range, not the high end. You CAN set it high enough so that the minimum fan speed sounds like a small vacuum cleaner, but I would not set it that way for any length of time. I just tried it once to see what it sounded like with the fans running at a high speed (never heard them before). There is a max possible setting, so you can't set it to a crazy high number.
I use smcFanControl and have the fans set about 25% higher than the default speed. I still can't even hear them at that setting, so I figured I wasn't doing any harm and it may help my iMac run cooler (not that noticed any issues with heat).
I can't see how it would void AppleCare. Unless you set it to sound like a vacuum cleaner all the time (which would be really annoying), you are running the fans well within their normal operating range.
Note: The adjusted minimum fan speed is only in effect while smcFanControl is running in the background. It does not change any system or hardware settings. To go back to the default settings, just quit smcFanControl.

Question about fan control MSI MPower

Hi, Cosimo from Italy, sorry for my bad english.
I have a question about fan control with the MSI MPower.
The MPower site says: All 4-pin PWM fan connector Onboard
But the manual says: SYSFAN1-4 pin 4 No Use
My question is: the Control Center Fan Utility support the fan connect SYSFAN1-4 3 Pin voltage controled or 4 Pin pulse width controled or both?
Thanks Cosimo.

The fans will run as per your percentage setting in the BIOS.
I can't find the percentage setting in BIOS...

Question re: fan replacement & smc fan control

hi all,
a few months back, i installed smc fan control and have been using it to run my fans at 6000rpm in an effort to keep my operating temps down (average now is about 115*F).
so, obviously, running my fans at 6000rpm for what is pretty much a continuous time will wear them down faster. my question:
will my fans be covered by apple care? i've got a plan valid for 3 years (i've had my MBP for about a year now). should i expect anything to happen to the fans within this timeframe?
thanks in advance

Hi blikebecks23,
When you start up your computer, it's already at 115 or it climbs to that temperature after normal usage? Personally, that's pretty normal operating temperature for these machines. I went to instal SMC Fan Control prior to responding and with my machine "idle" and having a few tabs open in Safari I'm sitting at 117 degrees and the fans at idle of about 2000rpm.
With that being said, I really don't see the need to run the 3rd party application, the built-in temperature monitoring logic for the machine is adequate enough to properly cool the unit.

Z87 Gaming Boards - Questions regarding fan control / soundblaster cinema...

Hello everyone,
I'm thinking about switching to MSI Z87-G45 Gaming (currently using Asus Gene-Z V), however there are three issues that I've been unable to find information on:
1) Fan Control
The new msi boards seem to have new bios fan control which enables you to set a low temperature and corresponding fan speed, aswell as high temperature which marks the temp when the fan will reach 100% speed. However I've read that this is only available for the CPU_FAN1 header and not CASE_FANX or even CPU_FAN2 (if available). Is that true?
2)Audio Solution
The middle boards seem to feature Realtek 1150 in combination with the software solution Soundblaster Cinema (Xpower as X-Fi MB3). Now the soundblaster cinema really confuses me, is it better than the X-FI MB2 (thats the software solution of the asus Z77 rog boards)? Does it have the "soundblaster console" in addition to thx true studio pro or is it just the thx utility etc.?
3) VGA Boost in combination with msi graphics cards
What exactly does this do? It says that it automatically increases the power target, but is that useful if you also use msi afterburner?
Thanks.

Thanks for info, I ordered a G45-Gaming today and let's see how it works out.

Can you control 3 pin fans with this board?
BTW first post here :-)
I can update you on this issue once I get everyone up and running, however generally msi had the following setup:
CPU_FAN headers -> pwm control (and sometimes voltage too)
CASE_FAN headers -> voltage control only (= 3 PIN fan)
The "old" case fan control sucked though since you could only set a range from 60% to 100% on the fans whereas for cpu fans you could set 0 to 100%. Also the minimum temperatur for case fans was 40° which in makes case (case temp never rose above 35°) made case fan control pretty much useless.

User-developed 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.id=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/S10FanCtrl1.0.0.1.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=7a3fb99d33817c08c2b435915e8821d7e04e75f6e8ebb871, 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/hilfsprogramme-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=1476. 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.

Great opening post Carsten!
The latest bios:
http://www-307.ibm.com/pc/support/site.wss/document.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.

Z87-G45 Fan Connection Questions

Greetings,
I wanted to ask about connecting my Corsair liquid cooler. I'm using 2 radiator fans in a push-pull config, plus the cooler itself needs power. The Z87-G45 has 2 cpu fan connectors.
My first question is am I going to get fan control from this mobo? All my fans and cooler cables are 3-pin. I was given the impression that you might need 4-pin fans for variable fan speed control. Is that true?
If I am somehow going to get fan control from the mobo, I'd appreciate some advice on what goes where. Should I hook up the cooler power and one of the radiator fans to the CPU fan connectors and then the other radiator fan to a sys fan connector? Or would it better to have the cooler power on a sys fan connector? Better yet, is it safe to use a Y-connector for both of the radiator fans. I can't get a clear read on whether or not there is enough power for that and also whether it might screw up the BIOS readings for fan control (if that's a factor). I'm also one connector short for all the fans I want to run, so a Y-connector would be ideal. The 2 radiator fans are identical (Corsair AF120 - 12v/0.40a). I've read people write they *think* the max amp for each connector is 1.0, but I can't find anything definitive (it's not in manual).
If you're confident about any of this, I would appreciate your advice.
Thanks,
Bobby

Thanks for replying to one of my posts yet again Nichrome. You are an invaluable resource for this forum.
I did a double-check, and the Corsair fans are 3 pin. It's a shame; I wish I had studied this b4 I bought them. They are the loudest fans in my system. 4 pin fans, surprisingly, still seem to be very much the exception. Doing a search on Newegg for 4 pin fans, most of them, where I could see a picture of the plug, were of the old power supply molex variety.
Am I right to believe that the fan control for the CPU fan headers would be based on the CPU temp and the Sys fan headers would be based on either the mobo temp or the general temp of the air in the case? That will confirm for me if it's a bad idea to hook up the radiator fans to the Sys fan headers.
Thanks,
Bobby

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?

Proper Fan-Control by Lenovo?

Hello Everyone,
two weeks have passed since i got my Thinkpad L530 and for the most part i am happy with it. But there is one issue which gets on my nerves:
- the absolute annoying pulsing of the fan !!!
For me one of the most important reasons to buy this laptop were the good test-results about noise-emission and battery-duration, because i use this laptop for work. Therefore annoying fan-sounds are unacceptable.
To solve this issue i have comb through serveral forum-threads and finally found a solution for my Win7-OS with TPFanControl. But i also use Xubuntu and on linux there are currently no working fan-applications for the SL- / L- and some E-Series
What i have read about i'm not the only one with that problem and that issue seems known for ages....so my question is:
- WHY do we still have to use third-party programs to get this problem solved, with the risk of breaking our hardware? Is it that hard for lenovo to offer a proper fan-control for their devices?
Greetings, Christian W.

ArchSoarer: thanks. This thread is almost a zombie, but I have tried your "acpi_osi=Linux" boot command. It does make the fan operate correctly EXCEPT where one suspends or hibernates, in which case I still get fan problems. I have outlined the situation here on our wiki: http://wiki.archlinux.org/index.php/Tos … llite_L300 and have a link there to an attempt to fix the issue by disassembling the DSDT. I have yet to go any further and attempt to fix the DSDT errors in this laptop. For the moment, because Arch boot quite quickly I simply do not use hibernate or suspend on that laptop.

Lenovo S10-3 Fan Control (Linux) and overheating

Good day to everyone.
Let me describe the situation. My Lenovo S10-3 is always hot (even in idle) and uses internal fan very often. It irritates very much because fan is noisy (service found no problem).
Sensors: acpi-tz ~60C, core ~50C (idle).
But even fan is disabled (connector is pulled out from motherboard) temperature becomes not much higher --- approx 65-70C.
Now, the question: is there any way to override BIOS fan control values? (e.g. 55C="Fan on" to 60C="Fan On")
For the S10 series there is program named "Fan Control", but it doesn't work on S10-3 and this program is for MS Windows only. Can anyone give comprehensive ansver/guide how to control fan speed (or on/off temperature values) using native linux tools or special program? It might be very useful for others who experiences the same problem. Thanks.

The heatsink is not connected to the surface of CPU and GPU and this is why you said that disabling the fan doesn't make any difference in the temperature. There are two pieces of thermal pad on the CPU and GPU.They are actually unusable. Remove them. Put thermal paste on the surface of CPU and GPU and heatsink and then put a piece of copper on CPU and GPU. This will make connection between heatsink and surface of CPU. This will make the fan usefull . Do this at your own risk (There is no risk. But use suitable pieces of copper is very important.) Using google will help you find about this issue

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.

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

Fan / RPM questions...

I've noticed that my MacBook Pro's fans seem to be running louder and in a somewhat quacking fashion. I've downloaded Fan Control and iStat, and between the two they have shown the fans running at an average of 5800 to 6000 rpm. That explains the hum almost quacking noise.
What I am wondering is, is this normal? Should it be running that high and fast?
I do tend to run multiple programs at once. Mozilla, MSN, World of Warcratf, and various others at one or any given time. Would this contribute to the rpm and it's loudness?
Is there a particular way to fix the loudness? Or do I just have to deal with it?
My main questions are just is it normal to run this high, and any way to reduce loudness.
Thanks in advance.

There's a definite maybe in here somewhere. . . .
If you have a lot of applications that use more of the processor, then Yes the fans will come on and they should stay on until everything is cooler.
However, this sounds somewhat more persistent than the norm, so I would start to delve a little deeper. I note that you already have the iStat application installed which is showing the speeds. Can I ask, are these speeds occurring as soon as you start up (or wake from sleep)?
I would suggest looking at the Activity Monitor utility (Applications>Utilities) and seeing which processes are showing the highest levels of processor use. Clearly, if one process is running away, that can be stopped (then monitored for repeat offending).
On occasion I have found a widget might be misbehaving, and recently the Firefox beta too. There are other processes which may be awry, depending on what you have and what you use.
WoW seems a possible -- I have seen this mentioned in other threads. If it IS just that one, then it may be normal (although I wouldn't like it). If there is nothing other than that, a trip to your retailer might be on the cards.

290x lightning bios for fan control?

Hi, would an updated bios fix my 290x Lightning not having manual fan control?
Serial Number: 602-v307-04sb1403020690
Here's a link to the bios:
https : //drive . google . com/file/d/0B0bFt35qm1QVeWNhMW55Nmk2Tk0/edit?usp=sharing
The forum wouldn't let me post a link, so it has six extra spaces. Apologies.
Two side questions:
1) Afterburner (even after a reset) says +63 on voltage. Is that a display error and though it says +63 it's actually at +0 extra, or is it actually just defaulting to +63 right off the bat? So, for example, if I set it to +100 would that actually be giving it +100 or just +37?
2) With Afterburner no longer being updated for new features, is there an alternative program that is continuing development?
Thanks!

For the vios:
Use the attached UEFI vbios versions to fix the fan issue.
TV307MH.101 is normal vbios, TV307MH.111 is LN2
Create a bootable usb stick (https://forum-en.msi.com/index.php?topic=165175.0).
Then unpack the previously provided archive (307_04s.rar) and put the included file (TV307MH.101 or TV307MH.111) on that stick.
Rename TV307MH.101 / TV307MH.111 to 101.rom / 111.rom. Put the atiflash.exe also included in the archive on the USB stick too. Now boot from the stick.
Type atiflash -p -f -noaper 0 101.rom (or 111.rom) [ENTER] and let it flash the vbios.

It is +63 by deafult (without changing values)? With Normal or LN2 vbios or both? Did anything change with new versions above?

I'm not aware of what you are talking as Afterburner is under development all the time. The latest version 3.0.0 final has just been released. >>How to use MSI Afterburner<<

MSI GTX 980 + Afterburner Fan Controll

Hio
i only have one simple question, will afterburner support fancontrol of both fans of the msi gtx 980 in the future??
thats the only thing preventing me to buy a msi gtx 980 because i dont want 2 seperate programms to have control of both fans... and i can only set custom fan curves for 1 fan with afterburner...
And as i heard with the msi fan control tool i can only set fixed speeds not fan curves.
the msi gtx 980 is already out now for over 6 month and still afterburner didnt support both fans... so i think it will not happend?
best regards
Knight

on several other forums that is discussed, afterburner only controls the gpu fan the other one can be controlled with msi fan control tool.
and yea 960 and 970 didnt have seperate fan controls, they bind together.
Exactly right. MSI decided to use two controllers on the 980. AB will not change in order to control both per the programmer of AB. Tell MSI not to do this kind of thing in the future if this concerns you.
