Does it matter which way you mount the radiator? Ive seen alot of reviews where the tubes are going into the top where as I mounted mine so that the tubes are going in on the bottom because of clearance issues in the ******** 1200. If I mount it on the bottom it hits the Heat Sink on my Northbridge, if I mount it on the top exhaust fan Tubes have to be on the bottom or I hit the Roof of the case.
