copper heat sinks aluminum heat sinks thin heat sinks COPPER HEAT SINKS This review will cover three of the newer copper heat sinks out on the market today. New copper heat sink line offers exceptional thermal solutions for electronic devices. Which material is better for heat sinks, copper or aluminum? "Copper heat sinks" have every advantage over aluminum except weight and machineabiliy. Contrary to popular belief, copper is better at both drawing in and releasing heat sinks. Copper heat sinks can also easily hold more heat then aluminum, but this does not affect its ability to release the heat it is holding. The design of a copper heat sink is more important then the material. Some people think that many heat sinks are designed with a copper base and aluminum fins because copper draws heat better and aluminum releases it better. Liquid cooled copper heat sink are designed in this way to reduce cost, ease manufacturing, and reduce weight. From a manufacturing standpoint aluminum is a much easier metal to work with than copper heat sink. Copper has integrated itself into the world of heatsinks over the last year while Aluminum heatsinks have quietly taken a step out the back door. Some of the earlier "distributor copper heatsinks" models released have included circular copper plates inserted into the base, and there have been entire copper bases with Aluminum fins. Nowadays, the complete Copper heatsink is really the only way to fly if you are serious about your electronic cooling.
