Windows10 High CPU Temp & Max Fan Speed After BIOS Access
After entering BIOS on my B760 motherboard, my CPU temp spikes to 80-90°C and fans run at full speed. It was normal before what’s causing this?

It is normal to run at max speed before the bios loads its settings in. If you already Set a Fan curve, you might have connected them wrong. I think if your Fans are wired over the case and not the mobo, you cant change the speed.

Restart the computer after resetting the BIOS to its default settings.

Sometimes, entering BIOS resets or changes certain settings like CPU voltage, fan profiles, or power management options, which can cause increased temperatures.
