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?

Thing is i dont know how to enable CPU fan control/regulation ifd possible. Doesn't realy see anything anything in the mobo manual except mentioning AMD Cool’n’Quiet.
This fan i have installed is running fine but i thk it runs full speed all the time and that makes a lot of noise - not needed.
Thx for any advice/tip/hint

40 °C is fine. The minimum fan speed can be set is a % of the full capacity.
Start with 12.5% and if the fan needs to adjusts it's fan speed too often and it get's annoying you can raise it to 25% or more.

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.

Fan Control Option in the EM

Can Lenovo enable the fan control option in the EM?
I know I can install other versions of the EM software but, I won't have the yellow color improvements found in the Yoga specific EM.

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.

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

How to control system fan

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.

P100-240: Toshiba GPU driver is old, Nvidia driver doesn't enable the fan?

Hi,
I was wondering if Toshiba could explain their choice here.
My laptop recently got sent in for repair because it burnt itself out due to me using Nvidias own drivers on my p100-240 (pspa3e).
The problem here is that:
a) Toshibas drivers for this card are well over a year old and sometimes buggy in new games
b) Toshiba does not seem to have followed the Nvidia spec (that or there is a major ACPI issue in their bios...)
so, Upon using the Nvidia drivers the laptops fan does not kick in, sending the systems temporature up to 106cand finally turning it off. It turned back on but basic graphics acceleration then failed to work.
SO, can we get an updated driver build? OR some kind of fan control app? or can you update your bios to enable nvidias drivers to function?
I feel like I cannot use my laptop for its purpose at the moment- I have reverted to installing a non-ACPI pc driver to force the fans to stay on which works well but then basic system functions like turn off do not work.
I have also been advised that this design flaw could be considered to make the system "not fit for purpose" under which case I could just return the laptop under the Sale of Goods act.
Though really, i'd just like to get my system working properly. It's bad enough not being able to run Linux on it, but even worse that windows doesnt work properly with it with official drivers.
One final question: Can I get the older BIOSes? several fixes work with them but not with the 4.0 bios (mainly linux fixes but as long as one OS works I don't care!)
Any tips on this are also welcome! Thanks for your help. :-)

Hi

If you want to hear anything from Toshiba then you have to contact them. This forum is only a user to user forum and unfortunately you will not find anyone from Toshiba here.
But maybe you want to hear my opinion;
>My laptop recently got sent in for repair because it burnt itself out due to me using Nvidias own drivers on my p100-240 (pspa3e).

Well, many Toshiba notebooks are delivered and equipped with the same graphic cards. Maybe you have to look in other notebook series which are delivered with the same card for a newer GPU driver.
But, you are right and generally the Toshiba graphic drivers are a little bit older as the original one from GPU manufacturer.
Why? First of all the nVidia or ATI original drivers are not designed for the notebook usage. These are drivers for desktop PC graphic cards. I visited the area for mobile drivers and found a info that I have to look on the notebook manufacturer site!!! This said everything!!!!
>b) Toshiba does not seem to have followed the Nvidia spec (that or there is a major ACPI issue in their bios...)
As mentioned above the original GPU drivers are not designed for the notebook usage.
Why? Because the notebook GPUs cannot be cooled like the graphic cards for the desktop PC!!!
The Toshiba own drivers support an overheating protection which helps to avoid an GPU damage!!!!
The original nVidia or ATI drivers do not support such overheating protection!!!
If you want to use such drivers, you can do this ONLY at your own risk!
>Can I get the older BIOSes?
It seems Toshiba page provides only the newest BIOS. Maybe the authorized service provider can help you and could send you an older BIOS version.
Two years ago I contacted the ASP in my country and got a early version of my BIOS for the A50

Fan control on the G450 with Windows 7

Hello to everyone!
A lot of you might know that when Windows 7 launched, there was a week of "windows 7 deals" from Lenovo.
Since I'm off to college in a year, I couldn't of brought a great laptop (like a $1000 model), so I stuck with the ideaPad G450 from Lenovo (949CHU) which I think was on day 3. I didn't want a 15" inch laptop, since I'm blind, so really screen did not matter - in deed this laptop has 32 MB of dedicated graphics ram which is way to little!
Anyway. I got the laptop yesterday, and it came with Windows 7 x64. My screen reading software currently only has an x86 release, so I decided to format the laptop with my own Windows 7 copy.
w
indows 7 installed very fast (I really just love the speed on this laptop!)
I went on the drivers folder in my Lenovo partition (I didn't repartition the disk, thinking that I could somehow save the IBM_service partition for later recovery/exporting to a DVD image, but that's a whole other issue)
I installed the energy ssaver driver. Since it was only in an x64 distribution, I downloaded it from Lenovo's site.
But I've noticed that the laptop's fan is constantly on. I don't know why, but it just never stops! It's not too loud or anything (just a tad bit, especially in my bedroom), I'm simply wondering what's up with this.
Is there some kind of driver I need to get that'll enable Windows to control my fan spin? Or is my only option to just have it run and run and run?
Thanks so much for your help
With all due respect-
Tomi

Hi
With the help of Google translate, I was able to get the program up and running. (there wasn't an english.lang file on the site, so I just used google translate to make my own).
It's a very neat program but sadly it won't change my fan settings, no matter how much I move the sliders around. The temperature sensors also show 0 ºC (there are 7 listed).
So I'm assuming that the program isn't detecting my laptop's fan settings fully (though it does find a battery).
Very odd...
With all the best-

Dell Vostro fan control mystery

When I first installed Arch on my Vostro laptop back in October '12, I had to run the i8kmon and i8kutils to get the fan control to work. Without it, the fan was blasting at full speed all the time, no matter what the CPU temperature was.
However, this week I started noticing odd behavior in my fan control, in that the i8kmon service would start, but fail silently and the fan would remain off, no matter the temperature (not good). Here's the mystery: I disabled the i8kmon.service and since then my fan control is now BETTER then ever! The fan speed gradually increases and decreases based on system load, it's perfect.
Does anyone know what may be going on here? Perhaps the 3.8 kernel now supports this fan without special drivers? Of course, it could have been from earlier than 3.8, but I always had i8kmon running...?

Use the special key combo - It works on most Dell systems
Shift + FN + 1 5 3 2 4 from a VGA tty console - three lights will flash and one remain flashing. This enables a special Thermal management settings screen. Press FN + R to access it, you can change the fan speed, adjust the throttling and so on.
I need to set the fan speeds to 6000 and 5000 RPM, after which i8kfan 2 2 will reach max speed. Don't use this mode from within X, the system suspends everything else when in that mode and it goes into a VGA console, so things can screw up with the Wifi and the video adapter sometimes.

P45 Neo3-FR fan control

Hi there,
I've got the P45 Neo3-FR on my shortlist of motherboards to buy, but wanted to know if you can make the system fans temperature controlled in the BIOS. I see you can set them at 100% etc, but didn't know if this was linked to the temperature, or to the CPU fan speed at all?
Failing that, is there any MSI DDR2 P45 board that can do this?
Thanks,
Simon

what that 100%means and what for??
what it means is this do you want your fan to run at full speed(its possible Max speed) or lower when the software instructs the fan to cool the cpu as fast as it can. by selecting 100% it will run at full speed lets say 2000 RPM but if you select 90% it will run at 90% of 2000 which is 1800 RPM at this speed the noise is much lower but it takes a few more second to cool the cpu. its real purpose is to enable us to run the fan at a speed which its noise is tolerable.
with regard to other fan your mobo might have the software to control them or you may have to buy hardware to control them or buy constant fan speed 120mm at 1300rpm which are very quite and do a reasonable good job.

MSI Z77 mpower fan controll

MB: MSI Z77 MPower
In bios the auto option is avaliable only for CPUFAN and SYSFAN1 SYSFAN2. At the same time in ControlCenter it is possible to enable System Smart fan controll for each fan.
Is there any way to save selected options in Controll Center and automaticly apply them on sturtup?

Hi
CC shows very first settings taken from BIOS. So whatever its set in BIOS, CC will show this by default. And sadly cannot be changed to be applied differently. Yet you can change settings in BIOS and you should not need to use CC for fan control.

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)

RS480M2 - Cool'n'Quiet fan control fails after hibernation

I'm using my RS480M2 as a HTPC base.
Works great (integrated s-video out is NICE!)
Cool'n'Quiet works great when the system is booted normaly but efter hibernation the fans doesn't reduse speed.
Anyone knows anything to fix this?
Maybe disable Qool'n'Quiet fan control i bios and use speedfan instead?
My current config
WinXP Pro SP2
Latest reference drivers for Chipset/Graphics from ATi
Latest reference drivers for sound and LAN from Realtek
Athlon64 3200+ (90nm winchester core)
2x512Mb twinmos DDR400 cl 2,5
60Gb 2,5" Hitachi HDD
Any Ideas?

I always use speedfan in the BIOS and leave C&Q enabled.
As C&Q does more then regulating the fan, it also regulates the speed of the CPU.
But you can remove corecenter for fancontrol and use speedfan in the BIOS.
