The Scythe
Big Shuriken is actually a really small heatsink, well not
so much tiny as low profile. From the CPU to the top of the fan, the Big Shuriken
measures a scant 57mm tall. That's not a whole lot of space to cram in a
heatsink, but somehow Scythe have packed in four 6mm diameter heatpipes, 60
or 70 razor thin aluminum fins and a 120mm fan.
Low profile
heatsinks are classed in one of three different
sizes; 3U (slim cases) 110mm or less in height, 2U (low profile
cases) 75mm or less in height and 1.5U (HTPC, miniITX type cases) which
are less than 45mm tall. 1U heatsinks exist too, but they are often
dependent on forced air and rarely sold as stand alone coolers.
Weighing at just 405 grams the Scythe Big
Shuriken (SCBSK-1000) heatsink features four 6mm diameter copper heatpipes, a 10mm thick 119x119mm
square section of aluminum cooling fins, a copper base plate and a 120mm PWM fan that spins
at leisurely 900-1600 RPM. The heatsink stands less than 75mm tall, so it's firmly in
the 2U class and just a bit too big for 1.5U miniITX situations. The 12mm
thick fan has 11 impeller blades and is rated for 38 CFM at maximum speed.
Scythe's Big Shuriken heatsink is compatible with Socket
478, 775/1156/1366 Intel processors, and the entire AMD processor family from
socket 754/939 through to AM2/AM3. It retails for about $35 bucks at places like
QuietPC.

The construction of the Scythe Big
Shuriken is pretty simple, but the parts are so thin it's amazing the heatsink
is able to work at all. The four 6mm diameter copper heatpipes loop around the
CPU base plate and are soldered on one side only to a very thin, 10mm thick
panel of cooling fins.
The fan Scythe SY1212SL12M-P fan is slightly larger than all the cooling fins, which
are just 10mm thick. Because of the positioning of the aluminum cooling fins air from the 120mm
fan is exhausted downward and onto adjacent motherboard components, for added cooling benefit.

Heatsink Clips and
Brackets
The
Intel mounting clips supplied with the Scythe Big Shuriken heatsink
are designed with push-to-click pin that slide along a channel in
the bracket and therefore accommodate both Intel LGA 775 and LGA 1366 hole
spacings. Since socket 775, 1156, 1366 mounting holes are spaced 72mm, 75mm and 80mm respectively,
the hardware supplied with the Big Shuriken heatsink is unofficially compatible with Intel Core i5/i3 socket
1156 processors as well.
Scythe CPU clips are pretty straight forward; there are
three pairs of clips, one for socket 775/1156/1366, another pair for socket 478,
and the last for all AMD K8 processors (754/939/AM2/AM3). The clips lock into the side
of the base cap heatsink without the use of any tools, and are removable
by the same means.
For Intel processors the company relies on the standard
Intel push-to-click Intel C33389 reference fastener. For older generation Intel
CPUs, we even find a set of brackets for socket 478. All four generations of AMD
CPUs are serviced by one cam lever clip that engages on the central lug
of the AMD heatsink retention frame. Of all the heatsinks FrostyTech has reviewed
recently, this interchangeable clip system is the most convenient. The heatsink is held on firmly
and the appropriate amount of clamping pressure is applied - what more could you ask
for?
FrostyTech's Test Methodologies are 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 this heatsink, its acoustic characteristics,
and of course its performance in the thermal tests!
