Sunbeamtech's Twister 120 heatsink is built around three 8mm diameter copper heatpipes which are exposed at the base. The heatpipes pass through the raw aluminum fins (which have a dimpled surface texture for added measure) in a chevron shape, so fan orientation is printed on the top of the heatsink. Standing 154mm tall, the Twister heatsink weighs 631 grams and ships with two 120mm fans that operate at speeds of 2000-1000RPM.
