## Description

Product Description Legendary silence, epic performance and features 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 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 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 120mm PWM 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 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 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. ELEGANT LOOK Magnificent appearance in all details The all-black design combined with a high-grade fan sticker makes Silent Wings Pro 4 120mm 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.

Review: Amazing fan, really quiet - I bought these as just bought a Be Quiet Pure Base 600 case. I suffer from severe hyperacusis and my Fractal Design Define S case and fans were no longer cutting it. I swapped out the stock pure wings 2 fans and adjusted fan speed to silent in Bios and wow, I can barely hear any noise from my PC now. Excellent fans, worth every penny. I think these are even quieter than the Noctua ones I tried. Seriously amazing. I have a be quiet Dark Rock Slim CPU fan as well, never hear it.
Review: Very good thermals. - I’m running five Silent Wings 4 fans in my system, three 140mm front intakes, two 140mm top intakes, and a 120mm rear exhaust. Airflow is excellent and thermals remain consistently strong even under sustained load. The fans maintain good static pressure and stay impressively quiet at higher RPMs. Build quality is solid, and PWM control works smoothly. Highly recommended for anyone aiming for strong airflow without excessive noise. Highly recommend!

### ⭐⭐⭐⭐⭐ Good airflow
*by K***N on 27 February 2026*

This is a good quality pc fan, it’s quiet and keeping nice and cool compared to my old. Airflow is good and it has a switch for the max speed what I set to the fastest and the noise level is still good. Thought the price was a bit high at first but glad I purchased this fan once fitted
