		Removing 
					the heat sink of a IBM Power4 CPU:
			 
			
			  
			
			Everyone knows the pretty cool white thick IBM chips and CPUs with 
			the silver heat spreader on it and  
			the awful pins of solder. These 
			chips are really nice, but they will be nicer without the heat 
			spreader to see  
			the die core under it, and no solder pins
			on the bottom. 
			After killing some of these chips I found a way to remove it without 
			damaging the processor. 
			 
			 
			You only need a small electric driller and a carpet cutter. With the 
			driller you drill a small hole into the 
			heat spreader. You don't have to be afraid to destroy the white ceramic 
			under it, because ceramic is harder 
			than the steel of the drill. You only should make the hole in a 
			corner and not on the middle of the chip where you 
			will destroy the die core. 
			Then you can shore up the heat spreader with a self-cutting tapping 
			screw. It works great and I have done this 
			with many chips and I never damaged one.

			For removing the solder pins I use a carpet cutter. It's really easy 
			to cut these soft pins off the CPU. After 
			that you can grind the bottom with some sand paper. After that you 
			should polish it with the special polish 
			from my article " cleaning chips & CPUs". The result is really 
			beautiful.
