May 31, 2010 by Lawrence Lee
The Gelid Silent Spirit and Scythe Samurai ZZ are a pair of modestly sized
top-down CPU coolers with 92 mm fans. Such heatsinks are an appropriate choice
for the more common middle of the road processors found in most desktop PCs.
They are typically far superior than stock cooling solutions, but do not perform
nearly as well as large tower coolers. However, their size is an asset, particularly
in cases that are not wide enough to accommodate the plethora of big heatsinks
with 120/140 mm fans.

The Gelid Silent Spirit.
|
Though Gelid is a relatively new name in the business, it was founded by former
employees of Arctic Cooling, giving it instant credibility. Given the company's
provenance, it's no surprise to see the Silent Spirit's fan has the same style
construction as some found on Arctic Cooling Alpine series of heatsinks. As
It lacks a tradition box casing, its impeller lays naked, visible from all sides.
The four struts bend at the edges forming feet that stand on a ring which is
attached to a clip-on frame using soft fan isolators. Great lengths have been
taken to prevent the fan from directly touching the heatsink and to dampen vibration.
Perhaps most interesting of all, the bulk of the heatsink does not lay flat
— it is uplifted a bit to one side so the fan blows slightly off to the side.

Mounting hardware.
|
The Silent Spirit comes with nothing inside the box aside from the heatsink,
a pair of plastic place-holders, and a set of AMD mounting clips. LGA775 clips
are pre-installed, and a square of thermal compound is pre-applied to the base.
LGA1366 clips are available but must be purchased separately.

| Feature & Brief |
Our Comment |
| Quad Sintered Heatpipes |
Nothing special. |
| Unique Fin Architecture |
Of course. |
| Special Heatsink Angle Design |
The heatsink's 'tilt' is designed to
exhaust air a bit more efficiently than blowing it straight down. |
| Optimized Air Flow Concept |
We're still waiting for a heatsink manufacturer
to claim their product isn't optimized. |
| Intelligent PWM Fan Control Curve |
They claim typical PWM fans speed up
linearly with CPU temperature while their fan has a more exponential curve. |
| Anti-Vibration Fan Mounts |
Soft-mounted Arctic Cooling style fan. |

Scythe Samurai ZZ
|
The Scythe Samurai ZZ.
|
The Scythe Samurai ZZ takes a more straight forward approach. It's a 3-heatpipe
cooler with a straight up-and-down design featuring a 92 mm Slip Stream fan.
The fan is mounted in a polar opposite method to the Silent Spirit, with a pair
of wire clips that clamp on very tightly — they're actually difficult to
take off without pliers. If the two fans are similar noise-wise in free-air,
the Scythe would likely be louder given how it's mounted. The Samurai ZZ has
an inherent performance advantage though since the fan housing helps generate
pressure by directing airflow downward and the fan is closer to the CPU and
motherboard PCB since the heatsink isn't angled upward.
|
Included accessories.
|
The Samurai ZZ also boasts better compatibility. Its set of three mounting
clips allows it to be installed on all current AMD and Intel desktop platforms
and even socket 478.

Our Comment |
F.P.S. (Fast-Phase Structure)
Larger heatsink base and direct airflow towards lower heatsink block structure
to provide a high cooling efficiency with compact heatsink dimensions.
|
This refers to the smaller heatsink above
the base. |
Top Mount Fan
By pointing the airflow of the fan towards the motherboard, Chip sets and
MOS-FETs on VR modules can be cooled simultaneously. |
A simple downblowing cooler. |
V.T.M.S. (Versatile Tool-free Multi platform
System)
Improved version of Versatile Tool-free Multi platform System allows multi
platform installation without any tools on the latest Intel and AMD sockets. |
Looks more or less the same as the same
system used on the original Samurai Z 4 years ago. |
