be quiet! Silent Wings Pro 4 PWM 140mm (BL099)

DescriptionUNCOMPROMISING SILENCE AND PERFORMANCE Silent Wings 4 140mm PWM combines all the features of a virtually inaudible fan with an extremely powerful fan for the most demanding applications.

• Optimised fan blades for highest performance on heatsinks
• Low blade-to-fan frame clearance and funnel-shaped air outlet for extremely high air pressure 
• Virtually inaudible operation at standard speed
• 6-pole fan motor for reduced vibration and energy consumption
• Anti-vibration mounting with push-pin fasteners or screws 
• Extremely long service life of up to 300,000 hours
• Elegant design in all-black colour, with high-quality decoration 

Equally quiet and efficient operation The Silent Wings 4 140mm PWM is the fan of choice for all possible applications. Whether in a case, on heatsinks or coolers, features such as the fan blades optimised for silence and the funnel-shaped fan frame make the Silent Wings 4 140mm PWM a fan that does not recognise the compromise between virtually inaudible operation and high performance. Minimum distance for maximum air pressure The Silent Wings 4 140mm PWM provides maximum air pressure and thus a significant increase in system performance. This is made possible by the reduced distance between the fan blades and the frame. This allows the Silent Wings 140mm PWM to be used in even the most demanding configurations. For any application The Silent Wings 4 140mm PWM has 2 mounting options included. The pre-installed anti-vibration mount keeps noise-generating vibrations to a minimum. For coolers and heatsinks, the plastic mount is the best choice. What both solutions have in common is that they allow virtually inaudible operation at standard speed. The key to virtually inaudible operation when needed The 6-pole fan motor with 3 phases ensures very low energy consumption, less vibration and thus quiet operation at a maximum of 13.6 dB(A). Equipped with this state-of-the-art technology, the fan ensures smooth operation and thus reduces costs. For balanced operation The advanced hydrodynamic bearing (FDB) guarantees a very long fan life of up to 300,000 hours. In addition, it significantly reduces vibrations and supports the virtually inaudible operation of the Silent Wings 4 140mm PWM. Great looks on all sides Whether as a fan on the cooling or in the case: the Silent Wings 4 140mm PWM always makes a good impression. The all-black design combined with the high-quality sticker makes the fan stand out in any configuration. The Silent Wings 4 140mm PWM is a high-performance and incredibly good-looking fan.
