I've never been comfortable with prying the IHS off once one side has been cut through like a lot of people seem to do.. CPUs are very delicate things now and need to be treated with a little more care. Using the "gentlemens touch" I'm now 4-0 Not a single fatality so far, I've delidded 2 AMD CPUs and 2 intel CPUs, AMD CPUs are definitely trickier to do, one slip on the CPUs I done and I could of shaved off a SMD.
