The Kingwin RVT 12025D is an entirely different cooler from its sibling with the exception of its utilizing the Direct Touch Heatpipes. The RVT 12025D lays the convection fin/fan assembly parallel to the mainboard. Many folks with hot running mainboards really appreciate these, myself for one. While the RVT 12025D is nowhere near as tall as the RVT 12025, it makes up for it with a large 145 x 150mm footprint.
