When I replaced the factory fan (which has three wires) with this fan (which has two wires), my BIOS was no longer able to keep track of the fan's speed or if the fan was failing. I don't know how this sort of this works, but my only guess is that is has to do with this fan not having a third wire. After a couple years, the fan got noisy which required the occasional oiling. Then one day the fan stopped altogether. The chip melted and the motherboard became useless. A chipset fan does not need to be a fancy color, just just needs to be able to run without failing.
