The Scythe Shogun is a large low noise heatsink built around a
fairly recent heatpipe technologies. It works quietly enough to be a welcome replacement for computers using the
stock Intel Pentium 4 or Athlon64 heatsinks, its large size and large fan efficiently move
a large volume of air slowly through the many cooling
As quiet as the Scythe Shogun is, the heatsink is cursed by
a set of mounting mechanisms that are complicated and
unwieldy to install. The mounting plates rely on a bevy of flanges attached to
brackets, with screws and fixtures that are frustrating to access in the
cramped confines of a case. It should really take no more than a set
of screws or snap clips, so it's an unfortunate predicament because
the Scythe Shogun heatsink shows great promise at maintaining low operating
temperatures with moderate noise levels.
The Scythe Shogun weighs in a hefty 790 grams, and stands
to a towering height of 147mm above the CPU. The heatsinks' 120x120mm
hypro-bearing fan spins at between 700RPM-1600RPM, while producing at
most 45.9 dBA in our real world tests. Socket 775/478 Intel Pentium 4 and
socket 754/940/939 AMD Athlon64 processors are supported by this model.
It does not AMD's socket AM2 processors, however.

If you've been reading FrostyTech's heatsink reviews
for a while now, you'll probably notice that the Scythe Shogun's appearance is
a remarkably familiar one. The design of the Shogun heatsink is a
continuation of the series first brought forth by TS Heatronics' NCU-1000, and then later by Scythe with the NCU-2000 heatsink. TS Heatronics is the Japanese company credited with
inventing the Heatlane heatpipe, and heatsinks based on this technology are now
sold commercially under the Scythe brand.
The flat loop of metal which connects the copper base to
the cooling fins on the Scythe Shogun is what makes this heatsink tick, and
it is the Heatlane heatpipe. The device was invented by Hisateru
Akachi who called the device a "self-excited
oscillation heatpipe." It is commonly referred to as the "Akachi pipe;" we'll explain how
it all works in a moment.
The Scythe Shogun heatsink comes disassembled, with a small box of parts that
correspond to the different CPU mounting methods. The printed instructions come
in handy when it's time to put everything together based on the type of
processor it will be used with.
The basic process involves attaching a box-shaped
stainless steel bracket onto the base of the Scythe Shogun, or two flat plates
depending on the orientation of the CPU socket, then specific
tabs as necessary. If the Scythe NCU-2000 is going to be used on an LGA775
Pentium 4 system, there are a couple brackets to install onto the
well... the instructions are clearly illustrated, but within the confines of a
case it can quickly become tedious.
Whatever the CPU, the manufacturer recommends that the
Shogun heatsink be installed
so hot air blows up towards the power supply, or towards the rear of the
case if that is not possible.
FrostyTech's K8 Test Methodology is outlined in detail
here if you care to know what equipment is
used, and the parameters under which the tests are conducted. Now let's move
forward and take a closer look at the Scythe Shogun heatsink and the Akachi
Heatlane technology, its acoustic characteristics, and of course it performance
in the thermal tests!
