So one of my two 2080Ti Gpus is literally going up from 40% gpu fan when the temperature is 84, to over 90% (which makes a terrible noise) at 85.
I want to setup the fan control profile so that the gpu fan will go up a little bit sooner, but as far as I can tell, i need to enable coolbits. My OS is Ubuntu 20.04.
I have tried to create a file /etc/X11/xorg.conf.d/11-nvidia-coolbits.conf
with the following contents:
Option "Coolbits" "4"
But that enables only GPU0’s coolbits (I can’t control GPU1’s fan speed through nvidia-settings while I can control GPU0).
I have tried to include
Option "AllowNVIDIAGPUScreens" "false"
but that didn’t help.
How can I enable GPU1’s coolbits?
You can use this i guess.
Not without enabling coolbits.
I found similar conf files under a different path… recently had this working for myself on a single RTX 3090 … but when I added my GTX 1060 to the same system… only the 1060 seems to have fan control enabled…
$ cat /usr/share/X11/xorg.conf.d/10-nvidia.conf
Okay I now have full fan control on two GPUS in Ubuntu 20.04… where before I had only 1… what did I do? I reran the same ol’ same command and rebooted… and voila

sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration
I didn’t even need to edit the
xorg.conf after that… just reboot. Hope it helps!
