I have a video card which has fans (GTX 970) on Debian Bookworm (12.10).
Unfortunately the card is broken in such a way that the fans almost
never work, and I can't afford to replace it with one that isn't broken.
Changing the GPU's internal clocks has little to no effect on
temperature (or performance, oddly enough), but changing the CPU clock
speed does. So I wrote a script that modifies that for me automatically
based on the GPU temperature, and that usually works.
Not always though. I have 2-4 case fans (I forget exactly). Is there a
way to change their speed? Maybe that'd be enough. Thanks.
Possibly, depending on your mainboard. Presumably they're plugged into
that. There might be a driver for a fan controller on the board that you
can use to control them. Try the lm-sensors package to see what it can
discover. Failing that, or instead, your mainboard's firmware
configuration (artist formerly known as BIOS) might offer some fan
controls.
