360° View - Reeven Justice (RC-1204) Heatsink Information on Frostytech's test methodology is available here.
The 120mm PWM fan supplied with the Justice RC-1204 heatsink spins at 1500-300RPM and connects via a 4-pin PWM motherboard header. Six 6mm diameter heatpipes connect the 114mm tall aluminum fin stack to the base below. Each aluminum fin measures 70mm deep and 125mm side. The fins are 0.3mm thick and is spaced 2.0mm apart. The bottom-most cooling fin is elevated 44mm above the CPU for motherboard clearance.
The Reeven Justice RC-1204 stands 162mm tall and incorporates six 6mm diameter copper heatpipes. At the base is a nickel plated copper heatspreader and aluminum cap. The 120mm fan is held on with four plastic fan clips, four extra clips are included so a second fan can be installed on the rear of the cooler.
The base of the Justice RC-1204 heatsink features a nickel plated copper heatspreader measuring 43x42mm.

Base Finish and Flatness

Flipping a heatsink over to inspect the business end is often a simple indicator of overall cooler quality. More practically speaking, a heatsink is in many ways only as effective as the contact it makes with the processor - the flatter and smoother the better. Base finish is one of the criteria that Frostytech measure in the course of evaluating heatsinks, and it involves two distinct aspects. Surface Finish is the first; this is calculated with the aid of Surface Roughness Comparator that has a cross section of common machine surface finishes and their numerical surface roughness equivalents in microinches. The second is Surface Flatness. This is tested with an engineer's straight edge or proven flat surface, in two axes.

Reeven's Justice RC-1204 heatsink features a 2.5-5mm thick copper heatspreader which is likely soldered to the six heatpipes. The base has a very smooth surface finish, with surface roughness approximately 16 microinches or better. According to the straight edge, the base is flat in one axis and fairly convex in the opposite axis.
