Scythe "Summit" Mine Heatsink/Fan

The Mine's tower configuration requires heatpipes — three for each half. The two halves are mirror images of each other. Each consists of a stack of aluminum fins, spaced about half as wide as the Ninja's. Although Scythe points out that this requires higher airflow, the fins are still spaced more widely than many others. They should be a good match for the relatively slow 1,500 RPM fan that Scythe has included.

The fins are cut in a wave shape that keeps the width of the fin constant across its length, keeping the airflow impedance more or less constant across the whole fin. This is a good thing; it means that all parts of the fins should receive more or less the same amount of airflow.

In addition to the noise reduction that Scythe notes in their feature page, the wave shape of the fins has a secondary purpose. The small space between the fins and the surface of the fan should reduce the amount of pressure needed to force air through the heatsink. The wave shape also serves an aesthetic purpose: They look like mountain peaks in the distance. Perhaps it was this shape that inspired the name.

The fan is sandwiched between the two halves, and only the edges of the fan make light contact with the fins. There is some potential for vibration-induced noise here. A high speed fan may cause enough vibration to rattle against the fins, or perhaps cause the fins themselves to vibrate and resonate.

Wave shaped fins keep direct contact with the fan to a minimum.

Three copper heatpipes sprout from each side of the base.

The base is unremarkable for a tower heatsink: Smooth, polished copper that simply transfers heat from the CPU to the heatpipes without a fuss. The finish on our sample was well polished and smooth.
