note: i only have one 120mm case fan in at the moment that could be the problem but.. my pc overall is EXTREMELY slow, it can barely launch applications and runs games like CS:GO at around 30 fps and games like GTA 5 all low settings/resolution at 5 fps, basically unplayable. It's been having this problem for a very long time and has gotten worse and worse over the past year. I feel I should try and salvage some parts and build a new pc. I came to a few conclusions such as I may need more fans, the motherboard is bottlenecking other parts or my cpu is just completely fried. I did some cpu temperature tests and when playing GTA 5 and harder to run games my cpu is about 50 C. and when on the desktop it runs at around 40 C. Not really sure which parts are the problem. Thanks! -nebz

open task manager and check if anything is using up your CPU
