Changing the speed of the CPU-Fan with the "w83627ehf" driver

Hello Members,

I got a new CPU-Fan these days and it's extremly loud, when running with full speed, so I decided to figure out how to control the speed. My Computer:
Mainboard: Asus P5Q-E (Chip: Winbond W83667HG, Driver: w83627ehf)
CPU: Intel Q9550 4x 2.83GHz
Fan: Asus Triton 81
OS: ArchLinux 2.6.36-ARCH i686

sensors-detect: http://upload.dav1d.de/file/9be4acb1
I hope this is enaugh

After a while I was able to load the driver (w83627ehf) http://www.lm-sensors.org/wiki/FAQ/Chap … rnel2.6.31, then I tried to run "pwmconfig": http://upload.dav1d.de/file/69d1e793. None of these "tests" were able to stop my CPU-Fan...strange. Am I doing anything wrong, or do I have to use another tool? (To make sure, slowing down the fan works, I booted my old rosty windows...and it worked)

I hope you guys can help me...

thx so far,
d4v1d

Hi i have exactly the same problem.
Mainboard: Asus p7p55d-e pro with winbond W83667HG-B.

pwm1 for the chassis-fans works perfectly but not pwm2 for the cpu-fan.

In speedfan on windows booth chassis and cpu-fan works.

Anyone found a solution to this yet?

Doesn't the BIOS have any settings to manipulate the speed of mainboard connected fans?

Yes it does but its kind of crappy. After a couple of hours all fans turns up to full speed and wont slow down again until i reboot.
Today i noticed pwm3 does not work either with fancontrol. Have not tried speedfan on windows yet though.

I have my cpu-fan connected to the chassis-fan connector as a temporary solution.

But it would be nice if there was possible to control the other pwm modules.

EDIT: Darn, there is even a wiki page for this MB:
http://en.gentoo-wiki.com/wiki/Asus_P5Q-E

I did a quick search on the gentoo forums and found this:

Maybe this applies to your problem too and you have to load the asus_atk0110 module instead of w83627ehf.
