Hi, I added a Corsair(700)PS to my Dell(best buy) rig. This PS blows down instead of out the case. It blows straight down on the cpu which now has core temps that hit 75C and lock up comp. I took the side cover off the case and have a fan blowing in to it. Cpu core temps dropped from 72/75C to 67/69C. Gpu went from 80 to 70, but it was the cpu temps that were killing computer.

I did clean the dust bunnies out, it is a medium? case with 1 fan blowing out.

My Q's are, will a better cpu cooler resolve this or is a it a situation where I need a bigger case(and more fans)? Do comp stores like best buy sell decent cpu coolers?

Thanks, -Ger-
