NZXT Respire T40 Heatsink Review
 

At the heart of this 158mm tall heatsink are four 8mm diameter copper heatpipes and a 120mm, 68CFM fan. The heatpipes are all exposed at the base while the aluminum fin stack is pretty standard; there aren't any fancy leading edges, punched out cooling fin patterns or unnecessary plastic fan shrouds. The 120mm fan rotates at 1800-1300RPM and moves upwards of 68CFM through the heatsinks' 112x130mm fin stack.
