Hey guys. I got my pc back after repair and now gameplay is laggy unlike before. It has a new motherboard (sabertooth 990fx), psu (550w), and cpu cooling. which looks like this http://www.eteknix.com/cooler-master-hyper-212-evo-cpu-cooler-review/3/ which im wondering if it needs a fan attached

-video of my problem- excuse the skipping, but pay attention to how it slows and speeds
