Same here, my chipset fan is going (didnt last very long) and am going to unplug it tonite. I am @ 146fsb. I would replace it with the stock HS fan from my G3ti200 (replaced with Crystal orb), but don't feel like having to undo everything and take the mobo out. I doubt the chipset will be very warm with the fan disconnected, but if it is, I will have to put the HS fan on it.
