## Description

Product description NO COMPROMISE SILENCE AND PERFORMANCE Silent Wings 4 120mm PWM high-speed White is the fan 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 high-speed White a fan that makes no compromises between very quiet operation and high performance. OPTIMIZED FOR HIGH-END PERFORMANCE Silent Wings 4 120mm PWM high-speed White 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 high-speed White allows the user to run even the most demanding applications. DIFFERENT MOUNTING OPTIONS Silent Wings 4 120mm PWM high-speed White has 2 mounting options in the scope of delivery. 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 MOTOR 6-pole fan motor with 3 phases for very low power consumption, less vibration, and therefore quiet max. operation of 31,2dB(A). Equipped with this state-of-the-art technology, the fan provides smooth operation and makes for lower costs doing so. FLUID-DYNAMIC BEARING 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 4 120mm PWM high-speed White. ELEGANT LOOK Be it as a radiator fan or in the case: Silent Wings 4 120mm PWM high-speed White always makes a good impression. The all-white design combined with the high-grade fan sticker makes the fan shine in any system. This makes Silent Wings 4 120mm PWM high-speed White a high performant and an incredibly good-looking fan.

Review: One of the very best airflow fans on the market - I was looking to get the best low-noise but high performance fan for the single output of my case to balance with the 4 low-noise fans I had running for air intake. Originally I had Fractal Design Dynamic GP14 fan that came with the case but I swapped that to be an additional input when I upgraded to a higher powered Corsair ML140 Pro. With the Corsair fan performance was decent but I found it seemed to get a bit noisy at moderate speeds. Realistically, my cooling setup was always more than adequate, I didn't have any temperature issues whatsoever, but I am a bit of a nerd for good air cooling and just like upgrading something once in a while and it seemed like there was room for improvement here. I had the corsair for several years but I would occasionally do research on fans or watch the latest reviews and comparisons of fans on youtube. Eventually the time felt right that I felt like spending the money and that there were some good options to upgrade to. This fan has been a definite improvement capable of moving more air at lower sound levels. I also like that it has the headroom to push to even higher speeds than I need with my current setup just in case I ever feel like it or was trying to max my performance having fun overclocking and benchmarking. I didn't bother to do any recorded tests of my temps but my subjective experience has been that I am very happy with the performance as I created a fan curve for it that gives me what I want airflow wise and my computer remains quieter than it did before. I also stepped away from having my computer with so many LED lights so the transition to a fan without lights worked for me. A few months ago I made significant upgrades to my processor and my video card and this still handles everything I can throw at it with ease and quietness. I have been super happy with the performance of this fan and will definitely have them in mind next time I am building a system.
Review: Surprisingly good fan - Surprisingly good fan! I’m really happy with the airflow volume and the incredibly low noise level at around 600 RPM (on the 1100 RPM version). One important thing to note: there are two models of this fan available - an 1100 RPM version and a 1900 RPM version. The 1900 RPM model is noticeably louder (which is to be expected), making the 1100 RPM version a much better fit for my quiet setup. They look identical, so slowing the 1900 RPM version down to 600 RPM would probably yield similar noise levels, but my fan controller couldn't drop that low.

## Features

- Optimized fan blades for the highest performance on radiators and heat sinks
- Small tip clearance and a fan frame with funnel-shaped air outlets for extremely high air pressure;
- 6-pole fan motor and fluid-dynamic bearing for less vibration and very smooth operations; Very silent operation even at maximum speed
- Anti-vibration mounting with push pins and screwed installation option
- 5-year manufacturer warranty

### ⭐⭐⭐⭐⭐ THIS IS A QUALITY PRODUCT!!!
*by A***R on May 16, 2026*

THIS IS A QUALITY PRODUCT!!! I used it in a 2-pin configuration as a gas absorption RV refrigeration air circulation fan. I cut the four pin low voltage plug off. The wires are not color coded so it took a bit of sorting out to find the pos/ground wires. The fan is very quiet and for my application the three speeds is nice because of seasonal requirements. I’ve no longevity feedback but suspect it to be durable based upon the quality of the design. The rubber corner mounting points dampen vibration. High speed in summer and medium, low or off in fall, winter and spring.
