Hello.
I have a AMD FX-8120 CPU on a ASUS-M5A78L-M LX motherboard (https://www.asus.com/Motherboards/M5A78LM_LX/) on Windows 8.1 (previously had Win7 with the same problem).
A few months ago, suddenly(no changes in bios, no new software etc), my stock fan started working at best 1/2 the speed (and this with Speed Fan), which means CPU started to throttle down (from 3600mhz to 1400 MHz).
I changed the stock fan to a better one (cant find the case but it is a 'cooler master' or something and worth around 18 euro, which I installed with a decent silicon based thermal grease). Overheating problems started going down, the noise from the stock fan is gone also. The problem is, in some CPU demanding games, the CPU still overheats because the fan does not go at full speed (actually I think it does not even change speed). I disabled 'cool'n'quiet in bios, system cooling policy is set to 'active'.
TL;DR: cooler fan does not spin fast enough, barely half the maximum speed, CPU overheats and throttles down. Do you have any ideas ?
