Be Quiet! Silent Wings 4 120mm Fluid-Dynamic Bearing High Performance PC Case and Radiator Fan – BL092

No Compromise Between Silence and High-End Performance

The be quiet! Silent Wings 4 120mm fan is meticulously engineered to eliminate compromises, seamlessly combining a virtually inaudible acoustic profile with extreme cooling performance tailored for the most demanding applications. Whether deployed inside a restrictive chassis case, mounted on liquid-cooling radiators, or attached to high-end CPU heat sinks, this advanced fan delivers extraordinary airflow and static pressure without ever introducing distracting noise into your environment.

Optimized for High-End Heat Sink Performance

To achieve significant increases in overall system cooling efficiency, the Silent Wings 4 features heavily optimized fan blades designed with minimal tolerances. By shrinking the physical distance between the spinning blade tips and the outer frame, combined with funnel-shaped air outlets on the fan frame, the unit generates extraordinary static air pressure. This advanced aerodynamic design allows users to push air effectively through restrictive radiator fins and dense heat sinks, confidently powering the most intensive processing workloads.

Advanced 6-Pole Motor and Fluid-Dynamic Bearing

At the technological core of energy management lies a state-of-the-art 6-pole fan motor operating across three distinct phases. This advanced architecture results in very low power consumption, minimized mechanical vibration, and an exceptionally smooth operational footprint that limits noise to a maximum of just 18.9 dB(A) during regular mid-speed operations. Coupled with a high-grade fluid-dynamic bearing (FDB), internal friction is drastically reduced, enabling a staggering, industry-leading lifespan of up to 300,000 hours for sustainable, long-term operation.

Versatile Mounting Options for Any Purpose

Adaptability is built right into the package, featuring multiple distinct mounting solutions tailored for specific use cases. The pre-installed anti-vibration mountings utilize secure push-pins to minimize noise-generating vibrations when used as a case fan. Alternatively, dedicated screwed installation options are included as the prime choice for rigid radiator and heat sink installations, ensuring a secure and acoustically insulated fit across all setups.

Magnificent All-Black Aesthetics

Form meets function through a sleek, all-black aesthetic accented by a high-grade fan sticker. This sophisticated styling ensures the fan looks stunning from every viewing angle inside a glass-paneled chassis. Backed by a comprehensive 5-year manufacturer warranty, the Silent Wings 4 120mm stands as an enduring, high-performance investment in absolute quietness and superior thermal engineering.
