Just thought I'd let people know that it is possible to use two of Artic Cooling's Freezer 4 heat pipe radiators on this board. It requires buying an additional adaptor if your board didn't come with two installed (http://www.koolance.com/shop/product...roducts_id=103 and 4 3 mm screws). You also will probably have to trim the fins on the one nearest the AGP slot. I scored the fins using a razor knife about 2 mm away from the heat pipe and flexed it back and forth with needle nose pliers - breaks cleanly . with little effort. I haven't run temp tests yet but they are extremely quiet - the hard drives are louder.
