Hi, Ived just bought a new CPU fan w/c was a good suggestion( Tt Polo 735) Im plaaning to install it today, now my question is, their is a hole on my CPU (P4 3.4HT) i guess everybody knows thet a P4 CPU has a hole on the upper right hand corner, just wanted to know if I should remove the old paste on the hole before I apply the new one(Arctic silver 5) or just leave it there.
