I recently switched out my motherboard. I reapplied thermal paste and the heat sink is in the right place, but when I first turned on the machine the heatsink fan was insanely loud. after Windows booted up I opened up Open Hardware Monitor, and it showed my CPU core temps at around 90C!! My cooling is perfectly adequate; I do some pretty intense gaming on this machine and the CPU has never reached more than 65C, so something is obviously very wrong here. After reading some forums I think it may have something to do with the motherboard "overvolting" the CPU, because it gets really hot really fast. People say I need to edit or even reset the BIOS to fix this, which is something that scares me and I don't really trust myself to do. I noticed there's a switch labeled BIOS_Sel1 on the new motherboard that switches between A and B (came and still is set to A). Could this help? Any suggestions and/or solutions would be greatly appreciated. I'll probably just end up bringing the thing into my local Microcenter, but I want to know what I might be dealing with first. CPU: Intel i5 4460 Quad Core at 3.2 GHz. Motherboard: ASRock Z97 Extreme4.
