The fan management of the 18.Q3.1 driver seems to be broken beyond repair.
I'm currently experiencing emergency-shutdowns with my Vega Frontier Edition (Air Cooled), when the GPU is under stress.
The fan speed does not exceed 2000RPM when on "automatic", even though HBM temp = 87°C and HotSpot temp = 85°C.
When I switch from "manual" (>3000RPM to prevent the card from overheating) to "automatic", RPM go to 700RPM!
Has anyone else experienced this?
