I am new to building computers, Ive only upgraded simple things on the one I have. I just bought a x2 4400 and some arctic 5. I dont know much about how to apply it and if it is worth applying over something they might include, or if it already has the compound on it. If it does is it worth taking off? How would I go about cleaning it off? Is it possible for me to mess up enough applying the compound and putting the cpu in the socket that I could easily break something? Plz help my stupid self . I just hope I can tackle this by myself .
