I posted a thread a while ago about the stock heatsink on my FX-4300 3.8ghz Processor was overworking itself so I downloading CPUID HWMonitor to view the temps on my system. And here are the results while idling. http://share.pho.to/6BCtv And here are the temps when I am running a game http://share.pho.to/6BD4H. The temps are still relatively low but the heatsink fan is still running very loudly. I have also checked my bios to see if I could turn the speed down. And I still couldn't find the reason why the fan is running so fast.
