my pc works fine and temps are cool (up to 70 c when playing games) however a lot of the time when windows starts the fans spin at max .However, it shows 0 rpm on apps like CPUID sometimes it stops and returns to a normal rpm for a bit and even if its fine on windows start up it does the same thing later on. as well it is fine in bios and never does it in bios. just wondering if there is a way to fix this . Thanks!
