removing an epoxy'd hs on the gpu can be tricky. i used a blowdryer over the heatsink for a while and that seemed to soften up the compound (i've also read some folks putting the card in the freezer overnight). place a credit card on the pcb and a flathead screwdriver or butter knife as leverage to pry off the hs. be very careful not to force it off too much as the epoxy can take a piece of the gpu with the hs--as it did to my geforce4 ti4200 but was lucky no adverse affects happened to it. *knock on wood*

if you're lucky, your hs is only held down by push pins and are a sinch to take off. if you already know this, ignore this part as it'll be for others reading this post. on the backside of the vid card, you will see a small plastic cone-like thing sticking out. all that needs to be done is to squeeze the cone enough so it will fit though the hole.
