be quiet! Silent Wings 3: Case fan of superlatives
Even the design of the black fan differs significantly from the standard design and could be further perfected compared to its predecessor. The fan blades are not smooth, but provided with grooves to allow air movement. For this purpose also contributes the rounded hub.
The same applies to the frame. The vibration dampers are now easily changeable by simply deducted or upturned. They are each directed forwards and backwards, thus enabling a fixture which transmits little vibration. For this purpose, no screws are used, but plastic pins that are pushed into the gray attachments.
Additionally a special slide bearings made of copper was installed that no mechanical contact to the axis and thus has worked quiet and durable. The rotor slides on a film of lubricant, from be quiet! FDB (Fluid Dynamic Bearing) called. This is a major reason for the rated life of fabled 300 thousand hours, which corresponds to about 34 years of continuous operation. A special IC controls the motor and also reduces noise.
The controlled by pulse width modulation Silent Wings 3 Wings fans in the 14-centimeter format rotates at 12 volts at up to 1,000 revolutions and thereby promotes 101.9 cubic meters of air per hour. He is not louder than 15.5 dB according to the manufacturer (A). The voltage range in which the fan operates, is between 4 and 12 volts.
