are you using amdgpu.ko kernel driver? if so... https://forum-en.msi.com/index.php?topic=298468.0 Do you see the same powerplay error messages in the kernel log as described on that thread. There is a workaround to use fancontrol script from lm_sensors Also try reading your bios file from your card, if you can't it will print an error about PCIE MMIO BAR regions. I have a theory this relates to a buggy motherboard bios efi code - as do others.
