CPU fan operates normally at startup but halts during BIOS or Windows installation.
you have a 3950x running on an orus x570i, it works normally until it gets warm while idle or browsing. you found out the CPU fan isn't spinning properly—sometimes it does during startup but then stops once you enter bios or windows. this is unusual. what could be causing it? how can you fix the issue?
Verify if your bios includes options such as "silent mode" or "zero db mode" and turn them off. Upon restarting, it's suggested to configure a custom fan curve for optimal cooling and sound balance—search "Aorus custom fan curve" for guidance.
The fan is turned off and isn't in silent mode, but it's still not working. I set it to performance mode... the fan keeps stopping.
I almost damaged my motherboard when it shut down during a BIOS update, so I used QFFlash. The newest BIOS is now installed. The fan isn’t working yet, and the CMOS still needs clearing.
Ouch, that's concerning. After the bios flash, did you attempt to reset CMOS? Was it cleared before or after trying the flash? Why did the board stop working during the process? Did you accidentally press the power button? I'm curious about how the system reacts when the fan is turned off. Do you receive any alerts? Have you considered ignoring the fan speed setting in the BIOS monitor? Would switching to a different fan work? It might be that the fan issue is the problem, not the board. If none of this helps, you could re-flash the BIOS and always clear CMOS for safety.
i made the mistake of using the bios updater utility in windows..... it blue screened (that was not a pleasant moment). is there a way to clear the CMOS on an x570 without opening the Computer? its a very cramp itx build...... I really would rather not....
