Product description

• Silent Wings 4 140mm PWM is the fan of choice for all possible operations. Be it in a case, on radiators or heat sinks Features like the silence-optimized fan blades and the funnel shaped fan frame make Silent Wings 4 140mm PWM a fan that makes no compromises between virtually inaudible operation and high performance.
• Silent Wings 4 140mm PWM makes for extraordinary air pressure and, therefore, significant increases in the system s performance. The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 140mm PWM allows the user to run even the most demanding applications.
• Silent Wings 4 140mm PWM has 2 mounting options in the scope of delivery. The pre-installed anti-vibration mounting reduces noise-generating vibrations to a minimum. For radiators and heat sinks, the plastic mounting is the first choice. Both solutions have in common that they enable virtually inaudible operation at regular speed.
• 6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 13.6dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed.
• The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours. In addition, it reduces the vibrations significantly and supports the virtually inaudible operation of Silent Wings 4 140mm PWM.
