be quiet! Be quiet! Silent Wings 3 120mm 3pin Quiet Fan
Description
High quality 6-pole fan motor Durable fluid dynamic bearing Unique airflow-optimized fan blades Rubberized fan frame with funnel-shaped air inlets Three years warranty 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. In 12V mode a delivery volume of 80.47 m³ / h at just 16.4 dB (A) is realized at a speed of 1,450 rev / min, making good cooling performance can be associated with minimal noise. In addition, a three-part voltage adapter for 12V, 5V and 7V is, bringing speed and volume be lowered again clearly, so that even a use in Ultra-Silent systems is possible.
