Spire Air Force 120 LED (SP12025N7L4-B-PWM)
The Spire Air Force 120 LED
(SP12025N7L4-B-PWM) is an interesting product, although there's nothing
special about it with reference to packaging. The fan is boxed in a cardboard
box indicating its key features.
The
packaging
The fan doesn’t come with any accessories,
except for a cable.
The
accompanied cable
Made in China, it has a 5-year warranty and
is price at $15.0.
The Spire Air Force 120 LED looks very appealing.
The translucent frame and impeller appears contrast with the blue silicone
corners.
This fan is lightweight (133g), looking elegant.
The impeller’s diameter is 110mm though the motor is small with only a 41mm
diameter.
The frame’s interior is flat. We can be find
the company’s website address from the frame’s outer surface.
The
product viewed from a tilt angle
The blades looking like saber expand
towards the ends and have a very sharp edges. Thanks to PWM-based adjustment,
the Spire Air Force 120 LED can rotate at a speed of600 to 1,500RPM, releasing
an airflow of 62.4CFM and a static pressure of 1.76mm of water. Its noise ranges
from 10 to 22dBA.
The silicone pads in four corners are
another special features of this model.
The
silicone pads in four corners
Having the same purpose as silicone pins, these
4 silicone pads help to reduce vibrations and noise. They are also removable.
This model features a Nano bearing which is
seemingly a kind of a fluid dynamic bearing. We can only know its longevity
from its specs – 70,000h or almost 8 years of continuous operation.
The
fan’s motor
At its top speed, the Spire Air Force 120
LED consumes 1.44W at 0.18A. The startup voltage is not stated.
There are 4 blue LED lights in the frame’s
corners. The lighting system isn’t bright but it looks very cute.
The
operating fan
The cable’s length is 300mm.

Swiftech Helix 120 (HELIX-120-BW)
Swiftech is major in making components for
liquid-cooling systems but has one 120mm fan in its series. It is dubbed as Helix
120. In accordance with the official specs released, this fan is optimized for
liquid cooling systems plus able to produce a higher pressure in comparison
with common fans.
The white sturdy box offers information
about the fan and its specs.
The
packaging
There are no accompanied accessories except
for screws.
The
accessories
Made in China, the fan has a RRP of $9.95,
plus a 1-year warranty.
The Swiftech Helix 120 seizes 120x120x25mm
and weighs 159g. Its white 9-blade impeller contrasts with the black frame.
The model’s crescent-shaped blades look
long and thick at the ends and have sharp edges. The frame’s interior is flat.
The
product viewed from a tilt angle
The interior surface’s rim are smoothed out.
The impeller’s diameter is 108mm; the motor’s one is 41mm.
The Swiftech Helix 120 doesn’t have any
regulation technology, so its speed is fixed at 1,800RPM. The fan can create a
static pressure of 2.29mm of water and an airflow of 55CFM. The correlation
between two above parameters is shown in the chart below:
Pressure-airflow
correlation
Regarding noise, the level is 33dBA at the peak
speed. Swiftech adds that this fan is superior to the Scythe Gentle
Typhoon or the RDM1225S, from this aspect.
Comparable
chart
The Swiftech Helix 120 uses a Z-axis
bearing which is something lying between ordinary sleeve bearings and fluid
dynamic bearings. It has a groove letting the lubricating liquid flow inside, enhancing
the longevity. Hence, its service life is 60,000h or nearly 7 years of
continuous operation. The power specs are also interesting: 0.16A, a low power
draw of just 1.92W and a startup voltage of 7V. The length of the cable is 450mm.
