Summary: Deepcool's Gammaxx 400 heatsink stands 162mm tall, putting in the class of full tower CPU coolers. At the heart of the 654 gram heatsink are four 6mm diameter copper heatpipes which are exposed at the base. The rest of the heatsink is a pretty standard rectangular aluminum fin stack, no fancy leading edges, shapes or punched out cooling fins.
Summary: The Deepcool Gammaxx 400 is an excellent CPU cooler, with high cooling performance and a very low noise level. It is also easy to install and remove, and relatively inexpensive.
However, the easy installation system is also the weak point of the Gammaxx 400. Some users simply hate stock-like pressure clips, because they can bend the motherboard and, in some cases, expelled from the hole.
