Can't change GPU fan despite changing Coolbits

Support Graphics & Display
1

Hey there, I’m struggling with enabling nvidia fan speed control. I have changed the /etc/X11/xorg.conf to coolbits=4, coolbits=12 and even tried coolbits=24 but it makes zero difference. When I open Nvidia X Server Settings or even Green With Envy the fan speed setting is either invisible or simply impossible to enable.

How can I change my graphic cards speed?

P.S. I’m using 460.32.03 drivers. I did try rebooting.

Thank you

I have two NVidia cards installed. On one, the Coolbits settings are enabled, and on the second card, the thermal settings are listed as “Unsupported”. Which card do you have installed?

Hey, thanks for replying. I have one graphic card - Geforce GTX 760. Changing coolbits value in xorg.conf worked in Ubuntu 20.10, but for some reason doesn’t allow me to open fan settings in Manjaro :frowning:

The second card I have which listed the thermal as Unsupported is a Zoltec GTX 1650 so it just might be your 760 doesn’t either. Are there any Coolbit options that show up in the NVidia X Server settings for your card?

I use Coolbits 4 so I can limit my RTX 2070 to 160W to keep temps down. I crunch numbers F@H

Please post the output of inxi -Gazy and head -n999 /etc/X11/xorg.conf /etc/X11/xorg.conf.d/*.

Please forgive me for bad formatting, I’m not sure how to format the text on forum yet. Thank you!

I edited the formatting. For future reference, you need to use three backticks (`):

What I’m noticing is that you seem to have two more or less conflicting Xorg configurations. The first thing I’d suggest is that you remove (back up) /etc/X11/xorg.conf and /etc/X11/xorg.conf.d/90-mhwd.conf. And create a minimal configuration (/etc/X11/xorg.conf.d/90-nvidia.conf) like this:

Section "ServerLayout"
    Identifier   "layout"
    Screen     0 "nvidia"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device     "nvidia"
    Option     "AllowEmptyInitialConfiguration"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver     "nvidia"
    Option     "Coolbits" "4"
EndSection

and reboot.

Thank you. I followed the instructions but unfortunately no difference - still no fan control tickbox in nvidia x and green-with-envy :frowning:
