I always upgrade my CPU coolers. Use a top quality thermal paste. Step up from the Evo not that it is not good but there is so much more out there that can guarantee no overheating problems. Visit Newegg and use their system of where people have rated units they have purchased. If you look at the CPU cooler I used you better have patience installing it. I'd never use one again. I like the Cooler Master V6. Push pull configuration easy to install and gives great thermal protection. As always, just my opinion.
