I have a video card whose original heatsink is attached to the core with thermal epoxy (Creative brand vid card). Would soaking the card in isopropyl alcohol for a few days accomplish anything, or might that damage the card? I do of course know that running the card while it's still wet will cause many transistors to die early deaths; I just want to know if the soaking itself could damage any components.
I'm just a bit wary of trying to pry the heatsink off; the epoxy is fairly firm, and is covering the entire GF2 core. Twisting or prying may either break the PCB, or possibly pop the Geforce2 chip right off the board.
So far, heating it to very hot (maybe 150F - very painful to touch the HS) and then trying to pry or twist it off - no luck. The thing won't even budge. It's sitting in the freezer now; hopefully that will help a bit.
Using a hammer on computer parts - for once, it has done good.
While the card was still cold from a stay in the freezer, I put a small screwdriver through the hole that you can see on the bottom right of the pic, and tapped it with a hammer. Heatsink popped right off. I just hope nothing got damaged. Phew!
