Changing GPU fan speed

[pegasus35]

Hi i wanna ask how to change the speed of gpu fans i tried
cd /etc/X11
sudo nvidia-xconfig --enable-all-gpus
nvidia-xconfig --cool-bits=4
reboot
but after reset i got weird resolution someting like 960x540 but after deleting the xorg.cfg and reboot i got my native resolution
is there some way i can get the control panel work? THX all (drivers nvidia 390 ,gpu gtx 570)

Is there a specific reason why you want to change the fan speed? I have 2 different Nvidia cards in 2 different machines and they and their fans function normally. Both fans run at about 20% speed when doing normal stuff, but when pushed by gaming, the fan speed ramps up and keeps the temp down.

my fans dosent go more then 50% and i getting 90 c

[again?]

FYI works here.

Where/what is telling you that the temp is 90 degrees C? I find it hard to believe that the card would live any longer at that temp.

[pegasus35]

the nvidia x server settings if i game like payday 2 and my card handles 97c at nvidia website

[Autodave]

Well then. If Nvidia says it is good to 97C and you are running at 90C, I would say that it is working just fine. I wouldn't expect the fan to run any higher since it is already keeping it below the threshold.

To enable GPU fan settings in Nvidia X server settings, locate /usr/share/X11/xorg.conf.d/10-nvidia.conf, add the coolbits option there and reboot. It should look something like this:

Section "OutputClass"
        Identifier "nvidia"
        MatchDriver "nvidia-drm"
        Driver "nvidia"
        Option "AllowEmptyInitialConfiguration"
        Option "Coolbits" "28"
        ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
