The trend of CPU coolers these days seems to be focused mainly on one material - copper. Although copper is a much better heat conductor than aluminium, it won't make the heat sink perform better than aluminium heat sinks if it's not accompanied by a good design. Furthermore, copper coolers are extremely heavy and will therefore not appeal to some users.

Theoretically, an aluminium heat sink with a good design should perform as well as, if not better than, a copper heat sink of a plain fin design. Well, this is where Bitspower, a cooler manufacturer from Taiwan come in.

Bitspower currently features a few coolers and among them are the NP80D and NP60D coolers. The heat sinks of both coolers are made of aluminium. The design of the heat sinks are somewhat familiar but yet unique. We shall explore their design when we take a better look at the heat sinks.
