7900 XTX fan controls not working
I've tried LACT and Corectrl and both don't appear to be able to get my fans to spin.
Anyone knows a fix or is this card not supported?

Hm. I have a 7900xtx Pulse from Sapphire and can rev the fans with CoolerControl. I had to do some shenanigans to get my AIO recognized, but don't recall doing anything for the GPU
Able to mess with them inside Lact as well
What motherboard do you have, and do you perhaps have something set in the bios?
I fixed it manually just now
lact and corectrl didn't work, I'm on gigabyte z790 gaming x mobo if it matters
here's what I did
found curve interface with:
ls /sys/class/drm/card1/device/gpu_od/fan_ctrl/
made a text file using:
cat <<EOF > /tmp/fan_curve.txt
0 40 20
1 50 35
2 60 50
3 70 70
4 80 85
5 90 100
EOF
disabled ZeroRPM by changing value 1 to 0
loaded my text:
sudo cat /tmp/fan_curve.txt > /sys/class/drm/card1/device/gpu_od/fan_ctrl/fan_curve
commited with:
sudo bash -c "echo 'c' > /sys/class/drm/card1/device/gpu_od/fan_ctrl/fan_curve"
and it started working
then I made a script to auto start on boot
now my card isn't trying to heat up my entire room by sitting idle at 60+ temps
you probably should file an issue with lact dev
lact actually works now, idk how, perhaps making the changes made it recognize the file or something
I can even OC the card now, which was something it didn't let me before
