EVGA 2080 XC Black (08G-P4-2082-KR) Fan Issues Solution
I have been trying to solve the issue of the fans not spinning, reporting 0% and 0 RPM on my Evga 2080 XC Black (08G-P4-2082-KR). I have tried different VBIOS versions, checked all physical connections, different systems, etc.
Symptoms included: both fans spinning on boot, but not spinning once in Windows. One fan spinning, one fan not spinning. No RGB (still not resolved with this fix).
I was finally able to get my fans working again by installing GPU Driver version 556.12. My VBIOS version is 90.04.23.40.70.
I ran DDU and removed the most recent Nvidia drivers, uninstalled Evga X1, then rebooted. I then installed this driver and Evga X1 again, rebooted and then tested. Now my fans show up in X1 and ramp up under load.
Hopefully this helps someone in the future. I know how frustrating it was for me.
