Be quiet! Silent Wings 4 120mm PWM Fan
Silent Wings 4 120mm PWM high-speed is the fan of choice 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 a fan that makes no compromises between very quiet operation and highest performance. Silent Wings 4 120mm PWM high-speed makes for extraordinary air pressure and, therefore, significant increases in the systems performance. The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 120mm PWM high-speed allows the user to run even the most demanding applications. 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 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 is virtually inaudible when operated in mid-speed. 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.

I was really happy with these fans.The build quality is great and they're very easy to install.Great fans, especially if you're not looking for rgb. They are very quiet while running and are a significant upgrade from the fans that came with my case.

Amazingly quick delivery: Ordered yesterday morning and received - well packaged - this evening. I'll install the fans tomorrow, having no doubt this is a quality product that will do its job outstandingly well. Thank you Seller.
This is a good quality quiet fan. I have two of these mounted to the side panel of my case under my desk with a simple mesh filter and they are still virtually inaudible. The option of fitting with screws or plugs using different mounts is a nice feature and accounts for the slightly higher price. Overall though, these are good value.
Even quieter than be quiet SW3, better thought out, smart solutions for 2 different types of attachment. Very premium feeling when opening the package the fan was in.
quiet as i had hoped for
not actually silent, I have not set the fan to run at max speed but I can hear it and the sound is noticeably different as it speeds up. Have mounted it correctly as far as I can tell. Works fine as a fan though
