Hi, Ive got a gigabyte ga7-dx mobo ( http://www.gigabyte.com.tw/products/7dx.htm ) and I was wondering if someone can point me to where i can get a replacement fan for the chipset. It started making really kind of loud grinding/whirring noises a few weeks ago and im pretty fed up with it, I stuck my head in there and it seems to definately be coming from the fan over the chipset. Im assuming all i would have to do is screw that one off and put a new one on correct? Can someone that knows a little more about these things point me to what kind of fan i need exactly and maybe where to snag one? Thanks much!
