Product Overview

The be quiet! Pure Wings 3 140 mm PWM high-speed 3-Pack is a set of three black 140 mm case fans with a closed loop motor that keeps monitoring the rotational speed. If a fan grille or radiator creates resistance, the motor raises the speed back to the target RPM. Each fan reaches up to 1,800 RPM, moves 122.6 m³/h (72.2 cfm) of air and builds up to 2.44 mmH2O of air pressure, with a noise level of 30.5 dB.

With nine airflow-optimised blades and a high static pressure, these fans suit radiators, heatsinks and positions behind fan grilles, as well as ordinary PC case airflow. They connect via a 4-pin PWM header, so speed can be controlled from the motherboard. The rifle bearing is rated for 80,000 hours MTTF. The pack includes three fans, mounting screws and a 46 cm cable on each fan, and there is no LED lighting.
