Default 302.17 - GPU fan always at 100%, can not change the thermal settings

Hello,

since Ubuntu "Precise Pangolin" upgrade, my GeForce 8800 GT fan is always at 100%, it's very noisy!!!

On Ubuntu "Oneiric" I put this lines in xorg.conf:

Option "Coolbits" "4"

to enable thermal settings and control the fan.
It works great until I upgraded to 12.04:

at Xorg start, fan is at maximum speed. If I go to nvidia sttings to change the fan speed, my change are not kept when I click on "Apply":

http://www.youtube.com/watch?v=zuU1QNgUt6E

If I try to change the fan speed in command line:

# nvidia-settings -a [gpu:0]/GPUFanControlState=1

Attribute 'GPUFanControlState' (tipingouin-home:0[gpu:0]) assigned value 1.

# nvidia-settings -a [fan:0]/GPUCurrentFanSpeed=40

Attribute 'GPUCurrentFanSpeed' (tipingouin-home:0[fan:0]) assigned value 40.

nothing happened.

Thanks for your help.

LGDN.

I finally installed manually 275.43 nvidia driver and fan control works again. If you would like to try this soluce, don't forget to desactivate all the nvidia driver in jockey-gtk and uninstall all nvidia packages:

$apt-get remove --purge nvidia*

I manually installed the 295.20 drivers from nvidia official site, the same bug: fan always at 100% at xorg start and I can not control it. So this bug is related to nvidia 295.20 drivers version, not ubuntu packagers. So I stay with anterior version.

I have also the same problem. My environment: Quadro FX 3700, kernel 3.2.9 x86_64, xorg-server 1.11.4.

Just try with GeForce 8800 GT, Quadro 4000, FX 5600 and some other GPUs able to change fan speed with 295.20 driver. Please attach logs by nvidia-bug-report.sh script as root .

I reinstalled manually nvidia driver 295.20, I uploaded it on official nvidia web site.
My fan speed is 100% and modifying speed is not applied (read my first post).
I attached the bugreport.

In fact not only fan always at 100% but also my gnome-shell often hangs up at regular intervals. I had to switch to nouveau.
