Hi everyone, I have an X1900XT, and I replaced the stock cooler with an Accelero X2 heatsink. (like this) I'm having flickering problems in WoW and Apple have agreed to replace the card under applecare. Obviously I should put the stock heatsink back onto the card before returning it to Apple. However the Accelero X2 screws dont fit the stock heatsink screwholes, and I don't have the original screws anymore. Now I can't get the stock heatsink back onto the card. Any one out there that may have done this mod and still have the original screws? I'd be eternally grateful!
