BE QUIET PC case fan SILENT-WINGS 4 140MM PWM HIGH-SPEED DSP0000009771

PERFORMANCE AND SILENCE WITHOUT COMPROMISE

Equally quiet and efficient operation

Silent Wings 4 140 mm PWM High-Speed is the fan of choice for all
possible applications. Whether in a case, on radiators or heatsinks:
features such as fan blades optimized for silence and the
funnel-shaped fan frame make the Silent Wings 4 140 mm PWM
High-Speed a fan that makes no compromises between virtually inaudible operation
and high performance.


OPTIMIZED FOR HIGH-END PERFORMANCE

Tight tolerances for maximum air pressure

Silent Wings 4 140 mm PWM High-Speed generates extraordinary air pressure
and therefore significantly increases system performance.
The smaller distance between the fan blades and the frame makes this possible. For
this reason, Silent Wings 4 140 mm PWM High-Speed allows users to run even
the most demanding applications.


DIFFERENT MOUNTING OPTIONS

For any purpose

Silent Wings 4 140 mm PWM High-Speed comes with 2 mounting options in the
package. The pre-installed anti-vibration mount minimises
noise-generating vibrations. Both solutions have in common that they allow for
virtually inaudible operation at regular speed.


6-POLE FAN MOTOR

The key to virtually inaudible operation when needed

6-pole, 3-phase fan motor for very low power consumption,
less vibration and therefore quiet max. operation at 18.9dB(A). Equipped
with this state-of-the-art technology, the fan is virtually inaudible when
operated at medium speed.


FLUID-DYNAMIC BEARING

For sustainable operation

The advanced fluid-dynamic bearing (FDB) enables the fan to have a very long service life of
up to 300 000 hours. It also significantly reduces
vibrations and supports the virtually inaudible operation of Silent Wings 4
140 mm PWM High-Speed.


ELEGANT LOOK

Great looks from every angle

Whether used as a radiator fan or in a case: Silent Wings 4 140 mm PWM High-
Speed always makes a good impression. The all-black design
combined with the high-quality fan label makes the fan stand out
in any system. This makes Silent Wings 4 140 mm PWM High-Speed an
incredibly attractive, high-performance fan.
