I've got problem with the 80mm fan at the back of my SB61G2 - the one attached to the ICE heat pipe.
I think the fan is a bit unbalanced, unscrewed it doesn't make much noise at all. But when its screwed in place the vibration is amplified by the case. It'll run quiet for a while, then a bump will make it loud again..
Is this Zalman 80mm fan a compatible replacement: http://www.zalman.co.kr/eng/product/...=30&pr_name=f1
i.e will it screw into the housing okay? Is the power connector the same as the one on the motherboard?
