I run a i5 4670k OC'ed to 4ghz with an MSI GTX 770 Twin Frozr IV. when i ran prime95 and furmark my temps hit almost 70c and my GPU around 80c-85c. i dust my case every so often but i recently decided to move the case fan that was preinstalled at the top of the case as an exhuast (Zalman Z11 Plus) to the bottom of the case acting as another intake for my GPU since the temps were ridiculous. ive been thinking that i should pick up some new case fans for the top of the case. would it be wise? or would it not make a difference? btw the guys who built my pc did barely any cable management so i decided to zip tie the cables out the way, witch actually lowered my gpu temps by 2c.
