As computer microprocessors continue to ramp up in speed and power consumption,
modern motherboard components that deal with power management are subject to
an ever increasing amount of stress. Current high-end motherboards ship with
high quality components and heatsinks for the voltage regulators as manufacturers
expect enthusiasts to dish out even more stress through overclocking. It is
ironic that these same users typically use large side-blowing tower CPU heatsinks,
reducing the helpful top-down airflow most stock cooler units provide over the
components surrounding the CPU socket.
For those concerned about this issue, down-blowing heatsinks are better, though
they generally do not cool the processor as effectively, partly because they
do not blow exhaust out toward the back of the system. An ideal top-down cooler
would provide improved socket cooling without sacrificing much in the way of
CPU cooling proficiency.
Enter the Scythe Grand Kama Cross, a larger version of the Kama Cross, a modestly
sized cooler with only 3 copper heatpipes and a 100 mm fan. The Grand version
is much larger, featuring four heatpipes with airflow provided by a 140 mm Slip
Stream fan. It is unusual looking with the heatpipes curving inward so that
the ends cross each other in a "X" formation. The aluminum fins around
the heatpipes are tightly spaced, angled to direct airflow around the socket,
and surprisingly short, particularly at the ends. The total area of the fins
is lower than usual for a heatsink of this size.

While Scythe has introduced hard mounting systems for some of their heatsinks,
the Grand Kama Cross, despite weighing 750 grams, ships with S478, AMD, and
LGA775/1156/1366 mounting frames that utilize stock mounting mechanisms. On
the Intel side, not only do you have to deal with push-pins, but for LGA1156,
the pins have to be slid halfway between the LGA775 and 1366 positions. There
is nothing to lock the push-pin in place, which can result in a mounting that
is off-center. The only good thing about these frames is they can be rotated,
which is useful for the Grand Kama Cross since one side is much wider than the
other. If the heatpipe ends are arrayed vertically, it could interfere with
the power supply in many ATX tower cases.

Our Comment |
Top Mount Fan
By pointing the airflow of the fan towards the motherboard, Chipsets and
MOS-FETs on VR modules can be cooled simultaneously.
|
Blowing down on the motherboard has its
advantages, but this usually results in poorer CPU cooling compared to heatsinks
that blow out the side. |
Slip Stream 140 mm PWM Fan
By applying the new SLIP STREAM140 fan, wider area of components on the
motherboard can be cooled compared to 120mm fans while keeping low noise
and high cooling ability for the CPU.
|
120mm Slip Streams perform well and have
excellent acoustics. The Grand Kama Cross uses a large 140 mm PWM model. |
4-Way Mounting
4-Way (direction) mounting is available. This allows you to configure the
optimized airflow direction inside your chassis without and restrictions.
|
Like many Scythe coolers, the mounting
frame is secured from the bottom with a square hole configuration, allowing
it to be freely rotated. |
