The fan on the chipset cooler of my mainboard is on its last legs (the bearings are shot and its making a racket inside my otherwise quiet PC). Anyone know where I can get a replacement HSF combo (they are one unit on this mobo), or a passive cooler that will fit? The passive cooler would have to be low profile, as the end of my graphics card hangs over the northbridge - the max height would be about 10 mm.
