I had to remove my I7 from my motherboard because it didn't function anymore. Now this I7 had already some cooling(i didn't add any of it!) paste on it when i first added it, but now since i removed it, some of it i had to clean off the motherboard.
I'm now about to add it again to a new motherboard.. do I need to add new cooling paste or is it still ok?
Add new paste, but don't over do it, Less is more, 1 drop about the size of a pice of rice, and the cooler should spread it around, And then tighten the the 4 screws in a star pattern to spread it around.
