Engineered in Germany for enthusiasts who refuse to compromise, this fan is the definitive choice for demanding PC builds, offering an unparalleled blend of extraordinarily high performance, progressive features, and the signature near-silent operation that defines the be quiet! brand.

Performant, Progressive, Quiet Pure Wings 3 140mm PWM high-speed are the perfect addition to demanding PCs with extraordinarily high performance and progressive features such as a speed-regulating closed loop motor. This makes the fan a versatile companion for your gaming system. Its iconic design lets anyone immediately recognize it as a be quiet! fan and adds a touch of elegance to any configuration. This fan is meticulously optimized not just for maximum case airflow but also for impressive static pressure, making it a superior all-around solution. Whether used as a chassis fan to exhaust hot air or mounted on a high-performance water-cooling radiator or air cooler, it delivers outstanding results.

The advanced PWM functionality allows your motherboard to intelligently control the fan´s rotational speed, ensuring it runs whisper-quiet during idle or light tasks and dynamically ramps up to provide powerful cooling when you´re pushing your system to its limits during intense gaming or heavy workloads. This intelligent control provides the perfect thermal headroom without any unnecessary noise. At the heart of its consistent performance is the innovative closed loop motor technology. This feature acts like cruise control for your fan, constantly monitoring and adjusting the rotational speed to maintain the target RPM, regardless of air resistance. This results in remarkably stable and efficient operation under all conditions. Durability is a cornerstone of its design, thanks to the proven rifle bearing technology, which guarantees a remarkably long operational lifespan and sustained quiet performance for years of reliable cooling.

The be quiet! Pure Wings 3 140mm PWM high-speed is not just a component; it´s an aesthetic statement. The timeless, all-black design, coupled with the unique surface structure of the fan blades, provides a sophisticated and professional look that complements any high-end build, from minimalist workstations to vibrant RGB-lit gaming rigs.
