The be quiet! Light Wings 140mm PWM high-speed is a high-performance cooling fan designed to keep your PC components cool while adding a touch of customizable light to your build. This 140mm black fan utilizes a 4-pole motor and rifle bearing technology to balance durability with a lifespan of 60,000 hours, ensuring it remains a reliable part of your system for years. With a maximum speed of 2200 rpm, it delivers a strong airflow of 71.7 CFM and a static pressure of 2.3 mm H2O, which helps push air through dense radiators or restrictive cases. You can manage these speeds via the 4-pin PWM connector to keep noise levels at a maximum of 31 dB(A). The integrated ARGB LEDs connect through a 5V 3-pin header, allowing you to synchronize the lighting with your other components. To simplify your cable management, the fan supports daisy-chaining, meaning you can link multiple units together before connecting them to the motherboard. Each unit weighs 251 g and comes with the necessary mounting screws for a secure installation in any standard 140 x 140 x 25 mm slot.
