Death by lapping

I've just finished lapping my Q9550 when I turned it back on and for a longer period than normal I was faced with a black screen. Crapping my pants I fiddled with the gfx connector and finally saw the login screen. Which then got me thinking.

Has anyone killed a cpu by lapping it ?

I've lapped 3-4 now, have done them all the same way using water and wet & dry 120 to 1500 grit. Although i've noticed my previous cpus that the edges were the first to start wearing away where as the Q9550 the edges were the last. Dunno if it's a different manufacturing process but I'd imagine the heat spreaders don't change ?

I always lap the heatsink.

I saw around a 15'c drop from an unlapped e6600 and heatisnk in a full case to a lapped heasink and cpu in a shuttle
