Hi, my CPU fan (Wraith Prism, 3700x OEM fan) is not working correctly. It spins on startup, then stops completely but actually spins for 2 seconds randomly every few minutes or so.

I tried connecting a case fan to the CPU_Fan header and it’s the same issue.

I tried connecting the CPU fan to CPU_Pump and that actually works.

Issue occured after leaving PC on BSOD ”Driver_Power_State_Failure” while i was at work, now the BSOD has stopped occuring (turned off power to PC, then back on, while testing fan)

So what’s the problem? Motherboard broken?

Motherboard: MSI X570-A Pro
PSU: Seasonic Focus GX-750W
