CPU stuck to heatsink
I'm switching my P4 to a new motherboard. When I tried to remove the heatsink from the old board, the CPU came out with it. Everything seems fine, and none of the CPU's pins are bent, but I can't get the heatsink off. I used the thermal pad that came with the heatsink, not thermal compound (I'm kicking myself for that now). I tried to wiggle them apart, but there is no movement whatsoever -- it's like they're superglued together. Is there any way to get them apart, or do I have to trash a perfectly good CPU?
thanks to all the suggestions yall have provided...the one that worked for me immediatly, was to use a small flathead screw driver and apply a little pressure to the corner between the heatsink and cpu top (((...((( the corner is the Key point 4 seperation )))...))) this is when you pull out the heatsink with cpu stuck to it.
The razor blade... didn't really work.. or was I too nice with it?
Anyways, this did work ...
The simplest way of removing a heatsink is to turn on the computer and run it for a few minutes to let the CPU heat loosen the heatsink.
If the CPU came out of the socket stuck to the heatsink, I think I'd try a hairdryer.
I think there's too much of a chance to chip the package and possibly damage the CPU by using even a small screwdriver.
I used a hairdryer on high and focused on the area where heatsink and processor meet and kept the heat going for about 5 minutes, turning it after a minute or so to get all sides heated up. With a decent tug all on one side, I managed to separate them with no issues.
Caution; there is a high chance you might bend a pin if you aren't careful how you are positioned when pulling the cpu apart from the heatsink.
Also, the heatsink becomes extremely hot, so I had to use a cloth to be able to hold the heatsink. It was an interesting adventure, but it worked.
I would recommend trying what another posted mentioned, and run the pc for 20-30 minutes to let the cpu and heatsink heat up first, then do the pull.
