Radeon heatsink Epoxied on?!

Today i was gona replace the dinky stock heatsink/fan on my Radeon 8500. when i had nvidia cards, i could slide that sucker right off, but with the radeon it wouldnt move. So i got a puddy scraper and a blow dryer and turned it on high and put it on there for about 2 mins. I started trying to pry and push the heatsink off from underneath... wouldnt budge. I think they use Epoxy on their cores which sucks . Instead of just retreating, I have this Active ram cooling kit, which comes with a midsized fan, about 1-1/2-2" tall. So i took the lil dinky fan off the Radeon heatsink, and bolted that sucker on there with the long screws that came with it. Now, i still have heat spreaders on my Ram, just no fan on them, and its on my radeon. If anyone knows any way possible to get the heatsinks off, plz let me know, i would appreaciate much, (u guys should try it, i can get 285 core stable
