Silent Wings Pro 4 120mm PWM White is the most progressive, performant and versatile fan by be quiet! IMPROVED ON ALL LEVELS 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 120mm PWM White have been developed newly from scratch. The new blade arrangement enables a performance second to none for all possible operations. Be it in a case, on radiators or heat sinks. OPTIMIZED FOR HIGH-END PERFORMANCE Minimum distance for maximum air pressure Silent Wings Pro 4 120mm PWM White makes for extraordinary air pressure and therefor, significantly increases the systems performance. The decreased distance between the fan blades and the frame enables an extraordinarily high air pressure. By that, the Silent Wings Pro 4 120mm PWM White allows the user to run even the most demanding applications. SPEED SWITCH 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 120mm PWM White 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. 6-POLE FAN MOTOR 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 36.9dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed. 3 DIFFERENT MOUNTING OPTIONS For any purpose Silent Wings Pro 4 120mm PWM White 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. FLUID-DYNAMIC BEARING 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 120mm PWM White. ELEGANT LOOK Magnificent appearance in all details Completely covered in white and equipped with a high-grade fan sticker, this fan is especially suited for white PC builds. 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.
