I had a problem with the fan on my Dragon+ board. I ended up buying a Thermaltake Blue Orb chipset fan. I think I got mine from Newegg. They have a couple of different fans listed for chipsets. I didn't have any problem replacing mine, just had to pull the board to release the spring clips from the bottom. Had to use thermal tape and not the replacement clips though. It is running fine and fairly quiet. Also, you might be able to contact ASUS and get a new chipset fan and be able to replace it, but I don't think I would get a replacement fan from the same people who gave me the one that is screwing up. Or you could RMA it, but that is a fairly big hassle. I guess its your call.
