120mm PWM Case Fan

The be quiet! Silent Wings 4 120mm PWM White is a single case fan built for builders who want low noise without sacrificing airflow. Its white frame and blades suit clean, all-white system themes. The fluid dynamic bearing and six-pole motor keep vibration minimal during continuous operation. It mounts with either push pins or screws for flexible installation.

Fluid Dynamic Bearing

The bearing type is the deciding specification for longevity and acoustic profile. A fluid dynamic bearing reduces friction compared to sleeve or rifle alternatives, enabling the rated 300,000 hour lifespan. It also supports the virtually inaudible operation at regular speeds that defines this model. Buyers needing a simpler, lower-cost bearing for light-duty builds should look elsewhere.

High Static Pressure Headroom

Optimized blades and a funnel-shaped frame outlet generate high static pressure, so the fan moves air through dense heat-sink fins or radiator channels without stalling. At standard PWM speeds it remains practically silent while delivering strong cooling headroom for overclocked CPUs or multi-GPU setups. In wide-open cases with no airflow restriction the pressure advantage is less critical, so pure airflow fans may suffice.

Domande su questo articolo

How quiet is the fan when running at normal speeds inside a PC?

The Silent Wings 4 is designed for virtually inaudible operation at regular speed, using a 6-pole motor and fluid-dynamic bearing to minimise vibration and noise.

What connector does the fan use and what control does it allow?

It uses a standard 4-pin PWM connector, letting the motherboard regulate speed automatically based on temperature.

What mounting hardware is included for installation?

The package includes anti-vibration push pins for tool-free mounting and also supports traditional screw installation.
