Abstract: If you need a silent heatsink, and I do mean silent, the Scythe Zipang is
the next best thing to a passive block of aluminum (the only truely silent
option).

The 25x138x138mm fan is held in place on the Scythe Zipang with a pair of
springy wire clips. The fan spins at a fixed 1000RPM and is powered
by a standard 3-pin fan header. With the fan removed we can see the
large array of stacked aluminum fins soldered to the top-half of six copper
heatpipes, and threaded over the other end of those same six heatpipes. The nickel plated
aluminum fins are 0.3mm thick and spaced 1.5mm apart. |

The
body of the Scythe Zipang heatsink is 30mm thick. The six 6mm diameter copper heatpipes
are soldered along the bottom edge and thread through the center of the
fins as well. Below all of this is a rather large extruded
aluminum base cap heatsink the heatpipes and copper base are soldered to.
The bulk of the Scythe Zipang is elevated 55mm above the base
for clearance purposes. |

The heavily chrome plated copper
base plate on the Scythe Zipang is 6mm thick, and 37.5x37.5mm in area.
The screw holes are for attaching the Intel LGA 775/478 and AMD mounting
brackets. The copper heatpipes loop around from the base in an 'e' shape
to contact the middle and bottom edge of the aluminum
cooling fins. Curiously, the heatpipes are kept rather closely packed at the
fin level, rather than spreading out to take advantage of the full 145mm
width of heatsink fin. |
