The 120mm PWM fan spins at 1800-800RPM and draws power from a standard 4-pin motherboard fan header. The manual fan speed controller is not removable. The fan is held by two wire fan clips which are easy to remove for cleaning. Six 6mm diameter copper heatpipes pass through half the aluminum fins in four separate rows, from the center outwards. Aluminum fins measure 0.2mm thick and are spaced ~1.5mm apart. The leading/trailing edges are shaped as previously described, which is quite a novel technique.

Scythe's Rasetsu heatsink stands just 130mm tall but has a footprint of 140mm x 130mm making it rather boxy. The bottom-most fin is elevated 44mm above the CPU socket for clearance. The six heatpipes are soldered together side to side at the base, behind a 2mm thick nickel plated copper heatspreader. The rows of heatpipes intersect the aluminum fins with a 20° skew to the left.

From the bottom the Scythe Rasetsu is a compact little bundle of heatpipes and aluminum fins. The same pattern is mirrored in the bottom of the fins as well. A polished nickel plated copper base plate measuring 47x50mm in size is more than sufficient for any modern Intel or AMD processor.
