   Thank you for that link Ray, never found it before but the solution in it (i.e. uninstalling Asrock A-Tuning and disabling "load kernel driver" in Aida64) solved the problem.

	This problem is often told with different AM4/TR4 boards. I would completely deinstall the A-Tuning SW and only use the bios for the fan control. After removing the A-Tuning SW, go to the bios and select default FAN settings, save and restart to bios and than apply your control curve. In any case, i would not mix bios settings with tool settings under the OS. Just for info, a bit similar: https://forums.aida64.com/topic/4168-aida64-kernel-driver-locks-cpu-fan-speed-asrock-x399-taichi-asus-zenith-extreme/

	This is still happening with BIOS version 3.80.

	I have a X399 Taichi board with a Threadripper 1950X on BIOS version 3.50 (the most recent). OS is Windows Server 2016. Whenever I apply a custom fan speed control curve to any of the connected fans, either through the UEFI GUI or the A-Tuning application in Windows Server, the change takes effect but but then reverts itself back to the original default configuration between 20 minutes and 2 hours later. The delay between the custom configuration being applied and the reset to default seems to be random. Is there a way to make it so a custom fan speed control curve can be saved and keep it from reverting back to default?
