Thanks for the tips. I'll get some thermal paste on order and be careful in my application. Does the heat sink come off rather easily? Any tricks or methods I should employ?

Just be careful popping the clips out from the back of the logic board.  Pretty much means pulling the logic board from the machine.

The heat sink has four metal clips that pass through holes in the logic board.  On the front they're part of a band of metal that holds the heat sink on the CPU.   They just pass through the logic board holes an 1/8" or so.
