I just installed a Zalman heatsink on my Radeon 9700 pro and now i get horrible artifacts in all of my games. I haven't done any overclocking to the videocard. Can anyone tell me what the problem is here?

Is the heatsink actually making contact with the GPU? The first run of Zalman passive cooler wasn't designed to touch the core of the card, so removing the GPU shim was necessary to make it work properly.......I think.

when i removed the old fan from the radeon there was dried thermal paste on the gpu. I tried removing it with alcohol but it wouldn't come off. i was afraid to scrape it off in fear of damaging the gpu so i just applied a new coat of thermal paste to the gpu. The heatsink itself should not be in direct contact with the gpu as long as you consider the thermal paste to be a barrier between the two.

Get Avon skin-so-soft...no kidding, and it will come right off without damaging the GPU or RAM. Best damn thing to remove paste out there.

LOL. Oh dear. Leaving on the old thermal paste is a bad idea. Basically there would have been no thermal transfer between the core and the heatsink. I suspect you have messed up your card. No matter what you do now its probably foobar. Unless you'r lucky and the gpu didn't reach 90c. I suspect it did though, or even higher.

Listen to GW! If you remove the old thick thermal pad, and reapply the heatsink without taking off the protective shim, your heatsink isn't actually touching your CPU.

So it's overheating!

BTW, use orange solvent (the kind they use to remove gum from upholstery) to remove the old thermal tab. WOrks like a charm with absolutely no effort.
