Silent Wings 2 92mm FanThe power supplies from be quiet! are known for their high quality, top performance, good equipment and above all a very quiet operating noise. With this experience, the company now also offers separate fans in the second revision, which continue the high-end claim. The name SilentWings reveals the fundamental design focus: minimal noise.
Even the construction of the black fan deviates significantly from the standard design and could be perfected compared to its predecessor again. The fan blades are not smooth, but provided with grooves to optimize the airflow. This is also helped by the rounded hub.
The same applies to the frame. The vibration dampers are now easily exchangeable by simply pulled off or put on. They are each directed forward and backward, thus enabling a mounting that transmits little vibration. For this purpose, no screws are used, but plastic pins that are simply pushed into the gray fasteners.
In addition, a special plain bearing made of copper was installed, which has no mechanical contact with the axis and thus works quietly and with a long service life. The rotor glides on a film of lubricant, from be quiet! Called FDB (Fluid Dynamic Bearing). This is a major reason for the stated lifetime of a fabulous 300,000 hours, which equates to over 34 years of continuous operation. A special IC controls the engine and also reduces noise.
In the 12V mode, at a speed of 1,800 rpm, a delivery volume of 32 CFM is achieved at a mere 16.9 dB (A), whereby good cooling performance can be combined with minimal noise generation. In addition, a three-part voltage adapter for 12V, 7V and 5V is included, which speed and volume are significantly reduced, so that even in Ultra-Silent systems is possible. In addition to 3-pin, the fan can also be directly connected to the power supply via 4-pin Molex.
