Hey all, So I've just purchased a http://www.newegg.com/Product/Product.aspx?Item=N82E16835103064&Tpk=cooler master tx3 To replace the stock cooling on my AMD 975. Im kind of sick of the loud noise my amd stock fan makes.. Anyway, when I put the stock fan on, it had a thin layer of silver thermal paste. I know when I go to swap heatsinks out, that stuff will be baked all over my cpu. Is there a safe way to clean it off in order to put new paste that comes with my new purchase? Or should I just slap some new paste on top of the old residue left behind from the stock heatsink?
