Scythe Mine Rev.B SCMN-1100 Heatsink Review
Scythe Mine Rev.B SCMN-1100 Heatsink Review
Abstract: The Scythe Mine Rev.B is a funny looking cooler, with a 100mm fan at the center and two separate columns of aluminum cooling fins on either side.

Information on Frostytech's test methodology is available here.

The Heatsink Fan:
The 100x100x25mm fan is mounted to the base of the Scythe Mine Rev.B SCMN-1100 heatsink such that it floats in between the two towers of zig-zagged aluminum fins. The fan spins at a very low 1500RPM, generating less than 37dBA in our measurements. It connects via a standard 3-pin fan header to the motherboard and supports RPM monitoring. The six heat pipe ends are covered with false nuts for the sake of appearance. Each aluminum fin is approximately 109 x 30mm in size.

Heatsink Side A:
The Scythe Mine Rev.B heatsink stands 150mm tall, and the fins make up 96mm of that height. The fan is positioned between the cooling fins so noises are muffled and airflow need not be strong to be effective. The aluminum fins are elevated 40mm above the base to provide clearance for capacitors or MOSFET heatsinks near by.

Heatsink Side B:
From the side we can see how the 100mm fan floats in between two sets of aluminum fins. The entire area of the fan is occupied by aluminum fins so the orientation is very effective. Wide fin spacing allows air to pass easily through the aluminum, reducing back pressure and decreasing noise because a slower fan may be used. Each aluminum fin is 0.3 mm thick and spaced 2 mm apart from the next. At the bottom is the extruded aluminum component the different mounting clips all lock into. The three heatpipes are soldered between the aluminum extrusion and copper base plate below, which is only 2mm thick. A thin highly conductive base is ideal for rapidly conducting heat energy away from the CPU and to the heatpipes.

Heatsink Base:
The copper base of the Scythe Mine Rev.B SCMN-1100 heatsink is 50x36mm in size and perfectly flat in both axis. The copper has a very smooth polished surface, surface roughness is at or better than ~8 microinches (excellent). 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.
