I just removed the soldered IHS from my Intel 3.2ghz northwood cpu. Firstly took apart a womans shaver and used the flexible blades to cut through the glue thing. Once all around I tried to lift it but couldnt. I then found out that the die was soldered to the IHS. Instead of heating it up with something I simply installed the CPU and ran it without a fan. The computer turns itself off at 90 degrees, checked that before hand, so around the temp. at which the solder melts. Some source said it melts at 85. So as soon as the pc turns itself off I took a screwdriver and pushed the IHS off. Then left it to cool and with lapped the die. I did this because the solder which melted dropped off in metal ball.

Probably wouldnt try this with my new Q6600
