Alpenföhn WingBoost2 Computer case Fan

WingBoost2, 12VDC, 19.6dB(A), PWM The first generation of WingBoost fans already proved it´s exellent performance in various reviews.
With the new aerodynamically improved wing geometry we could not only increase the airflow
but as well inprove the static pressure at lower noise.

WB2-Technology
Many users ask themselves…what are WingBoost´s? WingBoost´s are ridges on the
impeller that guide the air on the air-inlet side of the impeller. Using the WingBoost 2
technology air turbulences are reduced wich leads to a lower noise level at full speed.

S-Shape geometry
With the improved S-Shape geometry we could reach a higher static pressure compared
to conventional designs.

HD-bearing:
The new developed HD Bearing (Hydraulic Bearing) reduces friction noises to a minimum and thus enables to a quiet operation.

Plus Funktion:
The new WingBoost 2 is equipped with a "plus-function".
That means that a Y split cable has been attached to the PWM connector for a
second fan. Thanks to this split cable it is possible to control additional PWM fan
with the same PWM connector on the motherboard instead of using a cable adapter or a 3pin connection.
