I took of that whiny little fan from my video card months ago, and put an 80mm fan over it. This weekend, I decided to put on a CPU heatsink, since I bought my last CPU with retail packaging, just so I'd have a stock heatsink to mess around with
. Anyways, I took off the 80mm fan, decided I'd try a method I'd read about to get off the stock heatsink. Get the card running really hot so the glue softens and just pull the sink off. So I started up 3dmark 2001, and decided to wait for artifacts to show up, then turn it off and pull it off. It didn't work- the artifacts never started showing up. Everthing around the card was geting uncomfortably hot, but I didn't even get artifacts.
Though my stock speed Geforce3 Ti200 won't quite have the heat output of your card, its amazing how much more heat these guys can take than a CPU, my cpu started getting flaky in the high 60s when I still had my pally with a crappy extruded aluminum heatsink.
