Aerocool Dead Silence 120mm/140mm Fans
Best-case
scenario, most enclosures you buy today will include one intake fan installed
in the front panel and an exhaust fan in the rear panel, with some foregoing
the intake fan entirely to reduce the price tag as much as possible. But if
you’re building a powerful PC, you’re going to need a lot more airflow than one
or two fans can deliver. When it comes to air cooling, normally we’d caution
that your ambient temps will fall as your system noise increases, but
Aerocool’s new Dead Silence family of case fans take ultra-quiet to the next
level.
Aerocool launch their dead silent fan series(140mm
and 120mm)
Aerocool recently
sent us a blue 140mm and a red 120mm model. Dead Silence fans also come in
black and white, and all models are available in either 120mm or 140mm. Each
color fan comes with a quartet of matching LEDs, except the black fan, which is
unlit.
One of the first
things we noticed when we unpackaged the Dead Silence fans was the profusion of
molded rubber on the fan blades. The black portions are constructed of the same
hard plastic as the fan frame, while the colored portions are made of a soft
rubber, which Aerocool designed to absorb noise as air passes over the blades.
There are rubber inserts at each of the fan’s four corners that act as
vibration-quelling mounts; Aerocool calls them Silencer Blocks. The Silencer
Blocks also feature a unique pattern that first channels sound away from the
frame and then dampens it as the sound reaches the edge of the inner wall. The
underside of the blades features a polka dot pattern that Aerocool claims effectively
minimizes air turbulence that occurs under the blades. The blade angle has also
been tuned to maximize airflow while minimizing sound output.
The Aerocool DS Dead Silence 140mm fan in
operation
The Dead Silence
fan motor utilizes a fluid dynamic bearing design, which delivers the same
precision rotation as ball bearing-based fans and better shock protection than
sleeve-bearing type fans.
FDB fans also
have a fully lubricated shaft for less friction, lower temperatures, quieter
operation, and a longer life span than any of the aforementioned fan types
(greater than 100,000 hours). The Dead Silence fans have a low starting voltage
of 3V before gradually ramping up to the fan’s standard 12V, but you can force
them to operate in a low-voltage mode using the bundled 7V voltage reduction
cable. Other items Aerocool bundles in include four anti-vibration screws, fully
sleeved cables, and a 3-pin fan to 4-pin Molex adapter.
Aerocool even think they have what it takes to
beat out everything else
on the market and they aim to do it quieter than brands such as be quiet!
In our tests, the
fans (both 120mm and 140mm fans running at 1,500rpm) emitted barely a mumble,
just inches away from our ears. Using the 7V cable reduced the mumble to a
practically inaudible whisper. For those who think improving a case’s airflow
means sacrificing silence, Aerocool’s Dead Silence fans are here to set the
record straight.
