SILENT WINGS 4 - 120mm PWMNO COMPROMISE SILENCE AND PERFORMANCE Silent Wings 4 120mm PWM combines all features of a virtually inaudible with an extremely performant fan for the most demanding applications.- Optimized fan blades for the highest performance on heat sinks- Small tip clearance and a fan frame with funnel-shaped air outlets for extremely high air pressure- Virtually inaudible operation at regular speed- 6-pole fan motor and fluid-dynamic bearing for less vibration and very smooth operations- Anti-vibration mounting with push pins and screwed installation option- Super-long lifespan of up to 300,000h- Elegant look with high-grade fan sticker in an all-black design- 5-year manufacturer More NO COMPROMISE SILENCE AND PERFORMANCEEqually quiet and performant operationSilent Wings 4 120mm 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 120mm PWM a fan that makes no compromises between virtually inaudible operation and high performance. OPTIMIZED FOR HIGH-END PERFORMANCEMinimum tolerances for maximum air pressureSilent Wings 4 120mm 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 120mm PWM allows the user to run even the most demanding applications. DIFFERENT MOUNTING OPTIONSFor any purposeSilent Wings 4 120mm PWM has 2 mounting options in the scope of del*very. 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 MOTORThe key for virtually inaudible operation when needed6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 18.9dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operatedin mid-speed. FLUID-DYNAMIC BEARINGThe 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 120mm PWM. ELEGANT LOOKMagnificent appearance from all anglesBe it as a radiator fan or in the case: Silent Wings 4 120mm PWM always makes a good impression. The all-black design combined with the high-grade fan sticker makes the fan shine in any system. This makes Silent Wings 4 120mm PWM a high performant and an incredibly good-looking fan.
