The copper heatpipes running through the massive array of aluminum fins are the key to spreading the heat along the full length of the heatsink. At the point where they touch base and collect the heat, they are consolidated as close as possible for maximum effect.

Copper heat pipes with a smooth squared shape at the bottom maximize heat transfer from the surface of the cooper base plate. Design uses a premium thermal compound to make sure it outlives the competition.
