Be Quiet! Silent Wings 4 140mm PWM High-Performance Fluid-Dynamic Bearing PC Case & Radiator Fan – BL095

No Compromise Between Silence and Performance

The be quiet! Silent Wings 4 140mm is meticulously engineered to eliminate compromises, seamlessly combining a virtually inaudible acoustic profile with extreme cooling performance for the most demanding applications. Whether deployed as a standard chassis fan, mounted on complex water-cooling radiators, or attached to high-end CPU heat sinks, this fan delivers extraordinary results without ever introducing distracting noise into your environment.

Engineered for High-End Air Pressure

To achieve significant increases in overall system cooling efficiency, the Silent Wings 4 140mm features heavily optimized fan blades designed with minimal tolerances. By shrinking the physical distance between the spinning blade tips and the outer frame, the fan 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 the fan lies a state-of-the-art 6-pole fan motor operating across three distinct phases. This advanced architecture results in remarkably low power consumption, minimized mechanical vibration, and an exceptionally smooth operational footprint that limits noise to a mere 13.6 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.

Versatile Mounting Options for Any Application

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 plastic mountings are included as the prime choice for rigid radiator and heat sink installations, ensuring a secure and acoustically insulated fit across all setups.

Magnificent Aesthetics and Long-Term Reliability

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 140mm stands as an enduring, high-performance investment in absolute quietness and superior thermal engineering.
