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.
when you say 'broken' is it the card fan control or the fans itselves
that are deads ?
It's something in the software. The fans spin normally by finger, and
once or twice they've operated. Very rarely though.
because, if you are good at soldering or know someone that does, you can
just disconnect the fans from the graphic card, and -possibly via an
adaptator or soldering- connect these card fans directly to a +5 or +12v
line so it are always running, your graphic card will be happier than
with only the case fans doing the airflow... at lieast that is what I
will do :)
If this decides to stop working one day, I will definitely go for a
hardware mod like that.
