So... wait, are you supposed to replace the compound on your CPU at regular intervals? I've been using the same stuff mine came with since last June, but I really don't want to wrestle the heatsink off of the board. It was a pain to get it on, doing it a second time isn't really something I want to do.
Negative, sir. There is no need to replace your thermal compound with normal use. Now if you are constaly removing and reapplying your heatsink, then it will need to be reapplied each time you remount your cooler.
Though, after about 5 years, the stock cooling compound from OEM's such as Dell, HP, and Compaq, dry up and hamper cooling. But stuff like the Zalman Z-Paste I use, need no maintenance.

You sir, have just blown my mind. You will recieve the bill for repairs shortly.
