The single 140x38mm PWM fan spins at 2000-800RPM and draws power from a 4-pin PWM motherboard fan header. Each of the six 6mm diameter copper heatpipes extends from the base to the top of both 112mm tall fin stacks. Two thicknesses of nickel plated aluminum cooling fins are used on the Heligon HE01 as far as we can tell; 0.4mm thick fins spaced 2.0mm apart and 0.3mm thick fins spaced 1.9mm apart.

Silverstone's Heligon HE01 heatsink stands 160mm tall, 141mm wide and the first fin is elevated 40mm above the CPU socket. Heatpipes rise up through the 50mm & 30mm fin arrays with a pitch of 13mm or 14.5mm. The base incorporates a 5mm thick nickel plated copper heatspreader and 8mm thick aluminum block to distribute clamping forces.

The narrow fin stack (air intake side) is 30mm deep and has heatpipes spaced in a row. The wider fin stack (exhaust side) measures 50mm deep and the heatpipes are staggered. The copper base plate measures 38x42mm in size. Note the wire fan clip notches along the outside edges which allow at most, three fans to be hung from the Heligon HE01's cooling fins.
