Hi, I just got an awesome deal on a Mac Pro with its cinema Display, but there's a somewhat annoying detail: the fan from the Ati X1900XT kicks in very often (even when doing nothing special at all) and it's VERY noisy. It's a workstation, so I don't mind it being noisy, but this is a bit too much. I've done a bit of research, and at the time, people seemed to like the aftermarket Arctic Cooling Accelero X2 cooler. I wanted to know if there was some other model in their current product line-up that would work or if it was the only one. Here's their website but I'm completely lost, since I've never needed to do any cooling modifications. Would this be the right product? Is it the same for the one in Mac Pros? Thanks for your help, guys!
