Hi All,

Experienced an issue with my Fatal1ty B450 Gaming K4, the Fan Control is not working.
I have adjusted the temperatures & fan speeds in the UEFI, saved and restarted.
Used a stress test tool (aida64) and temperatures increased, but the fan speeds stayed constant.

Any ideas?

Thanks
Dr@gonXP

It definitely should be a sticky.  It would be even better if Asrock would either fix the bogus "CPU temp" sensor output, or get rid of it, because it doesn't work -- across numerous boards, not just the B450's.  My X470 Taichi has the same issue, and someone here with a Threadripper board sees it too.

Stuck Wink

This is indeed a common issue and this post should help others find the rather quick and easy workaround/fix.

Maybe we should put out a call for someone with an AM4 board where the CPU thermistor temperature actually works!

My X470 TAICHI have a same issue. CPU fan - only tctl monitoring. CPU sensor doesn't work.
