My motherboard (EP-8K7A+) has a small fan on it about 4cmx 4cm (picture here: http://www.pchardware.ro/Reviews/review.php?id=114) It sounds like it's on its last legs as it's making strange whining noises. I've had a quick search but can't seem to find anywhere that stocks them. Anyone know where I can get one from? Alternatively, is it possible to replace this with a heatsink? BTW, what is this fan cooling? Obviously not the CPU but I guess some kind of additional processor?
