360° View - Scythe Andy Samurai Master Heatsink Information on Frostytech's test methodology is available here.
The 120x120x25mm fan is held in place on the Scythe Andy Samurai Master with a pair of springy wire clips. The fan spins at a low 1200RPM, and is powered by a standard 3-pin fan header. With the fan removed we can see the staggering of the 6mm diameter copper heatpipes that thread through the aluminum fins. The body of the Andy Samurai Master is 125x100x50mm. Its aluminum fins are arranged 3-to-1 pattern for full length and short, so fin density around the six heatpipes is maintained.
Scythe call the overlapping fins shown at right the "Infinity Interleave Fin Structure". Every fourth fin is a different width, some 26mm and others 125mm wide. The voids between the aluminum fins are meant to aide slower airflow moving through the cooler with as little resistance as possible. Each aluminum fin is 0.25mm thick, and fins are spaced 3.25mm or 1.25mm respectively. The bulk of the Andy Samurai Master heatsink is 53mm above the base of the cooler. The extruded aluminum base doubles as the support frame for the different mounting brackets. Note how the 6mm diameter heatpipes are staggered 15mm as they enter the fin array from the base where they are packed edge-to-edge.
The six heatpipes are soldered between the aluminum extrusion and a 2mm thin copper base plate below.The copper pad at the bottom of Scythe's Andy Samurai Master heatsink measures a broad 50x52mm, and has a smooth polished finish. The base is generally very flat. The extruded aluminum section above the copper base provides rigidity and a place for the mounting clips to transfer force directly onto the CPU core.
