Hello! So I've just installed a XFX 6870 HD in my Mac Pro 3,1. Everything works fine OOTB, except the fan noice is driving me crazy. It's super loud even just surfing the web, and when playing games, it sounds like I'm on an airport or something. Does anyone else have this problem? Is there something wrong with the card, and if so, is there something I can do about it? Thanks in advance.
