I have a Powercolor 5700 XT with Radeon software version 19.12.3.
When I set a custom fan curve, it will work until the PC is rebooted or wakes from sleep, at which point it reverts to the default curve. The software will display the values previously entered, but it runs the default fan curve. It will start working if I load a saved profile, but only until reboot or waking.
Is this something that should work, or is there a bug?
