In the second part of the 120mm fan
discussion, we would like to talk about 27 models from 15 different manufacturers
with the rotation speeds of 1,350RPM and higher.
In the second part of the 120mm fan
discussion, we would like to talk about 27 models from 15 different
manufacturers around the world. These models feature the speeds of 1,350RPM and
higher. We are discussing products that have bearable noise as well as hi-speed
monsters which may blow up everything. Now, let’s check them out in alphabet
order.
Test products
Cooler
Master Turbine Master MACH1.8 (R4-TMBB-18FK-R0)
Cooler Master Turbine Master MACH1.8 appears
with a wavy box in which there’s a paper.
The
box
The fan’s technical specs and key features
are listed in the back of the paper. On top lies a plastic cap for the fan’s
motor, 4 silicone pins, 1 PATA power adapter, silicone spacers and 4
self-tipping screws.
The
accessories
The fan is made in China, priced at $16
plus 1-year warranty. It weighs only 110g. Turbine Master MACH1.8 doesn’t look
common due to its semi-frameless impeller incorporating 16 blades.
The
fan
With such impeller and frame, the fan has
some advantages in term of air flow in comparison with classic 120mm fans
because it can get extra air in from the blades’ sides. Cooler Master will talk
about this concern in the next part:
The
semi-frameless impeller
With 16 blades, the impeller enables Cooler
Master to acclaim an airflow of 80.3CFM at a speed of 1,800RPM (compared to,
for example, 62.7FM at 2,350RPM of Corsair’s 120mm fan).
The fan impeller’s diameter is just 111mm
while its motor’s diameter is 40mm. The static pressure is measured at 1.96mm
of water. The noise level is 30.5dBA.
The key electrical specs are printed on
stickers.
The fan’s barometric ball bearing has a
life cycle of 100,000h (or more than 10 years for unstopped operation). The
impeller is detachable for cleaning or checking the internal motor:
The
structure
The Turbine Master MACH1.8 has higher power
consumption than a typical fan of the same series: 0.5A and 4.6W. According to
our measurement, it consumes under 3.4W yet that's very high anyway. It has a
3-wire cable which is around 0.5m long.

Corsair AF120 Performance Edition Twin Pack
The Corsair AF120 Performance
Edition continues appearing with the splendid coat of the Corsair fans.
Inside, the dual packaging includes two similar fans:
The
packaging
The packaging is very careful, indicating the
product’s name, rotation speed, noise level and other parameters along with key
features.
The fans are accompanied with a brief user guide,
an advertising booklet, two colored rings which can exchanged for each other,
screws, and a cable with step-down resistor.
The
accessories
Made in China, the product is priced $29.95
for a dual-fan kit. The fan is also available individually for $17. This
includes the 2-year warranty provided for all Corsair fans.
We may recall you that Corsair’s AF product-line
is specially developed for computer case, featuring an impeller with nine identical
flat narrow blades.
The diameters of impeller and motor are
112mm and 43mm respectively. The frame’s interior is flat.
The
fan viewed from a tilt angle
The rated speed of The Performance Edition
is 1,650RPM but you can turn it down to 1,100RPM by using of the accompanied
resistor cable. At the maximum speed, the fan releases an air flow of 63.5CFM,
static pressure of 1.1mm of water and 30dBA of noise. The silicone attached into
the corners of the frame are to reduce shaking and noise.
Similar to all Corsair models, the AF120
Performance Edition didn’t offer a life cycle. Its sticker indicates the
manufacturer, voltage, electric current and country of origin.
Power
specs
At 0.33A voltage, the fan is alleged to eat
below 3.96W of power. The startup voltage is set at 7V and the cable is 300mm
long. The fan’s weight is 145g.

Corsair SP120 High Performance Edition Twin Pack
The following is another hi-speed fan from
Corsair. The SP120 High Performance Edition is boxed as similarly as
the above is.
The
packaging
The packaging design didn’t change but the
color scheme did, it is blue instead of red, while the accessories are the
same.
The
accessories
RRP is $29.95 for a two-piece pack or $17
for only one fan. The product is made in China, offering a 2-year warranty.
Seven large blades of the impeller differentiates
this model completely from the rest of the fans participating in the test.
The
product’s picture
As you can see from our last review, the
SP120 is designated for high static pressure, meaning it is equipped with blades
which are large and almost flat, plus such thick ends.
The
fan viewed from a tilt angle
The impeller’s diameter is 112mm, similar
to that of the previous fan, but the motor’s diameter is 4mm larger (47mm). At
2,350RPM the SP120 is weaker than the AF120, regarding airflow (62.7CFM) but
its static pressure is almost 3 times as high (3.1mm of water).
Meanwhile, The SP120 High Performance
Edition has lower power consumption: 0.25A and 3W.
Power
specs
The startup voltage is 7V and the 3-wire
cable’s length is 300mm.
