I just got quite a few parts for a new system, one of them an Arctic Cooling Accelero X2 for use w/ a Radeon X1950XT. Instructions and reviews online say they come with thermal pads; I don't see any on my fan, nor do I see any in the package separately. Do these no longer come w/ the card or did I get screwed with a dud? Would using the ones on the existing stock cooler work?
