Okay, so thats not the problem. Just had to ask as i know serveral People who did remove it before installing :S
Well, reinstalling your cooler, not the CPU will make the thermal compund reseat to the CPU's top and if your cooler is screwed in the wrong way.
EDIT: This one, marked with red is the unit you are going to unscrew then "re-seat" or install agian.
When screwing in a Component like a cooler to the CPU its critital to get it lined up with the CPU. Screw the screws Down in a X-pattern. Do NOT screw one screw all the way first. Tighten them a a turn each in a X-pattern.
How i tighten screws:
Top left -> bottom right -> top right -> bottom left
This way i can sure that there is even pressaure on the whole CPU.Edited by MiiX - 2/6/13 at 1:47am
