The BE QUIET! Silent Wings 4 140mm PWM High-Speed White stands as a triumph of thermal engineering, merging an incredibly aggressive performance ceiling with a virtually inaudible operational profile. Designed for power users and enthusiasts, it provides the massive airflow required for the most demanding PC applications without the distracting acoustic footprint of traditional high-speed case fans. This makes it a formidable centerpiece for heavily overclocked systems and quiet workstations alike.
Optimized Aerodynamics for Maximum Cooling
Every structural element of this 140mm unit is meticulously optimized for peak efficiency. Designed to conquer the dense fin stacks of water-cooling radiators and heavy-duty heat sinks, the fan utilizes specialized fan blades tailored for immense performance. Working seamlessly alongside a highly advanced fan frame boasting funnel-shaped air outlets and critically small tip clearance, this combination ensures air is directed forcefully. The resulting output achieves an exceptionally high air pressure of 2.36 mm H2O and a massive airflow rate of 78.4 CFM, aggressively sweeping away internal heat.
Unrivaled Operational Smoothness and Lifespan
To sustain such immense output, a state-of-the-art 6-pole fan motor sits at the core of the fan, working in harmony with a premium fluid-dynamic bearing (FDB). This superior internal framework drastically cuts down on both electrical noise and physical vibration, yielding a remarkably smooth operation. The result is a fan that maintains a highly controlled maximum noise level of only 29.3 dB(A), even when pushed to its staggering top speed of 1900 RPM. This premium bearing technology extends reliability, yielding a super-long lifespan of up to 300,000 hours.
Exceptional Design and Versatile Mounting
Performance meets presentation with a striking, elegant all-white design that acts as a stunning visual upgrade for any contemporary showcase desktop build. Knowing that flexibility is key for custom loop builders and modders, this model is bundled with highly adaptable anti-vibration mounting gear. You are given the freedom to utilize an ultra-fast push-pin mechanism to further deaden case resonance or rely on a robust screwed installation option for heavy hardware mounting. Built for the long haul, this exceptional case fan is thoroughly backed by a 5-year manufacturer warranty.
