I have the exact same motherboard with a Q6600. If you're using the stock heatsink, which I imagine you are, I must advise extra caution with removing and replacing the heatsink. The plastic pushpins used to secure it are, "the most ******* stupid heatsink design ever." I've busted two of those such heatsinks now when reapplying thermal paste (two years in between, mind you) until I finally just bought a proper bracket-mount heatsink.
There is a correct procedure for doing it, look on Intel's website.
