be quiet! BL099 Silent Wings Pro 4 PWM - Case fan - 140 mm - 2400 rpm - Black

Silent Wings Pro 4 120 mm PWM is the progressive, performant and versatile fan by be quiet!

Key Selling Points

• Optimized fan blades for the highest performance on radiators and heat sinks
• Speed switch allows changing maximum PWM speed between medium-speed, high-speed and ultra-high-speed (up to 3000 rpm)
• Small tip clearance and a fan frame with a funnel-shaped air outlet 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
• Individual mounting systems for use as a case fan or with a radiator

Product Features

• Altered blade arrangement for new generation performance
  The fan blades are what makes a fan. It is for this reason that the fan blades of Silent Wings Pro 4 120 mm PWM have been developed from scratch. The blade arrangement enables a performance second to none for all possible operations. Be it in a case, on radiators or heat sinks.
• Minimum distance for maximum air pressure
  Silent Wings Pro 4 120 mm PWM makes for extraordinary air pressure and therefore, significantly increases the system's performance. The decreased distance between the fan blades and the frame enables an extraordinarily high air pressure. By that, the Silent Wings Pro 4 120 mm PWM allows the user to run even the most demanding applications.
• 3 speed options for any possible application
  The speed switch makes switching between medium, high-speed and ultra-high-speed of maximum RPM levels quick and easy. The Silent Wings Pro 4 120 mm PWM alters its application with a simple slide to the right. Medium-speed is suitable for any operation that requires regular cooling performance. High-speed lets the fan spin faster, providing more cooling power. Ultra-high-speed ultimately offers enough rpm to cool even the most demanding hardware in high-end PC builds.
• The key for virtually inaudible operation when needed
  6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 36.9 dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated
  in mid-speed.
• For any purpose
  Silent Wings Pro 4 120 mm PWM has 3 mounting options in the scope of delivery. The pre-installed radiator corners are specially designed for radiators on which the incomparable performance of this high-end fan completely shines. On the other hand, for chassis use, the anti-vibration mounting is the first choice as they reduce vibrations to a minimum. The plastic mountings round up the scope.
• For a sustainable operation
  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 Pro 4 120 mm PWM.
• Magnificent appearance in all details
  The design combined with a high-grade fan sticker makes Silent Wings Pro 4 120 mm PWM a highlight in any system. The finely sleeved PWM cable perfectly rounds up the outer appearance of the fan. Not only does the PWM cable look great: its connector can also be plugged in and out with ease, making the fan an eye-catcher and user-friendly alike.
