Product Information

Controllable, almost inadible and with exceptional cooling performance

The SilentWings 2 fan series offer the best available combination of performance and noise emissions paired with great reliability. Their secret: A unique, aerodynamically optimized fan blade design, special anti-vibration mounts as well as a high.quality fluid dynamic bearing for reduned noise emissions and a long lifespan. Thanks to this advanced technology these fans offer virtually inaudible operation without comprimising performance - the ideal compromise between excellent cooling and quiet operation.

In addition to this impressive combination of performance features, the speed of the SilentWings 2 PWM fans can be controlled via the Mainboard. When connected to a PWM port of a Mainboard or fan controller, the fan speed and hence performance and noise emissions can be adjusted as needed.

Features at a glance

Virtually inaudible operation

SilentWings® 2 fans are optimized for exceptional airflow with very low noise emissions by a multitude of electrical and mechanical improvements 

  • Unique aerodynamically optimized fan blade design reduces noise-inducing tubrulences
  • High-quality fluid dynamic bearing with copper core and high-grade oil prevents mechanical friction for even more quiet operation
  • Specially developed modular and tool-less anti-vibration mounts and a rubberized fan frame minimize the transmission of vibrations to the enclosure and other components
  • Optional mounting accessories for mounting with screws
  • Advanced high-end IC motor controller reduces electrical noise emissions

Speed control

  • With the pulse width modulation (PWM), the fan speed and hence performance as well as noise emissions can be controlled intelligently via a 4.Pin fan controller (as used in many Mainboards). With PWM your computer can increase cooling power as needed or may run as quietly as possible when it is permitted


  • Long-lived fluid dynamic bearing (FDB) with high-quality lubricant prevents direct contact between rotor and frame, significantly reducing noise emission
  • A copper core in the FDB efficiently removes heat from the bearing, hence allowing a very long lifespan of up to 300.000hrs
  • Dynamically balanced fan blades improve reliability and contribute to virtually inaudible operation
  • Product developement, design and quality control in Germany
