The 140x150x25mm PWM fan spins at 1500RPM and draws power from a standard 4-pin motherboard header. The fin stand measures 120mm tall by 52mm deep. The six heatpipes are spread out evenly through the cooling fins to rapidly conduct heat to two regions which receive the highest airflow from the fan. A portion of the leading and trailing edges of the fins have a saw-toothed profile.

The Noctua NH-U14S heatsink stands 170mm tall, but the bulk of it is elevated 45mm for clearance of adjacent board mounted devices. The six 6mm diameter copper heat pipes expand from side-by-side to a ~7mm & 26.5mm spacing as they pass through the fins. Each nickel plated aluminum fin measures 0.4mm thick and is spaced 1.5mm from the next. Note the wire fan clips used to secure the two fans in position on the NH-U14S.

The base of Noctua's NH-U14S heatsink measures 40x38mm in size. The copper base plate is 2mm to 4.5mm thick. The six 6mm diameter copper heatpipes have been soldered to copper base plates, and to the aluminum fins as well.
