GPU - set fan speeds (nVidia settings)

Hi, I like to set the fan speeds to a low audible level and air circulation in the box as well.

Usually I have to click buttons on the 'nVidia settings' GUI, every (re)boot.

I saw a post some where about setting fan speeds and worked out a way to have them start at login.

first I had to find out Display Name: gamesbox:0.0. from the nVidia GUI app 'X Screen 0'

then --display= would not work but found --ctrl-display= did the rest. Target fan speed is a (%)percentage.

nvidia-settings --ctrl-display=gamesbox:0.0 -a [gpu:0]/GPUFanControlState=1
nvidia-settings --ctrl-display=gamesbox:0.0 -a [fan:0]/GPUTargetFanSpeed=70
nvidia-settings --ctrl-display=gamesbox:0.0 -a [fan:1]/GPUTargetFanSpeed=70

The first guide was a ubuntu tute and suggested inserting the commands in
/etc/X11/xinit/xinitrc

That didn't work on my system, so I tested the commands with
/etc/rc.local

and it runs.

NVIDIA Driver Version:575.57.08
Graphics Processor:NVIDIA GeForce RTX 3060
uname -a Linux gamesbox 6.12.22+bpo-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.22-1~bpo12+1 (2025-04-25)
kde: 4:5.27.5.1-2

I hope this helps ...

regards Glenn

I am ignorant in the topic. But I had already burnt one GPU, experimenting with a very old notebook. Perhaps, one may better ask AI: What is the quietest PC fan?

Moore likely the other way around: Ask an AI, then get your GPU toasted.

@Glen: Thanks for sharing. Appreciated.
