I just completed a new build but my GPU and MOBO are not talking properly, so I ordered a different mobo which will be here tomorrow. I'm using a stock cooler for the cpu (i5), and need to remove it from teh old mobo and put it in the new one. Do I need to repaste the cpu when I do that? It's only been installed about 3 days at this point. Sorry for the novice question, I didn't see a straight answer about it and just want to be sure. Thanks.
