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.
