Ok so im not liking the temps that im getting out of my new Zerotherm Zen FZ120, so i have decided to reapply the thermal past and lap the Heatsink to make it shiny and smooth. I will not do this however if my the temps drop in the next few days, because people say AS5 has a break in period. Right now im getting 49C on speed fan for my E8400 and my case is well ventalated (Antec 900) so i came to the conclusion it must be the heatsink. I need some opinons on this as well as do i need to pull out my motherboard again if the back mouning plate is already on.
