be quiet! Pure Wings 3 140mm PWM high-speed White Computer case Fan 14 cm 1 pc(s)

Pure Wings 3 140mm PWM High-Speed White is a 140 mm case fan designed for high-performance PCs. It features a speed-regulating closed-loop motor for precise PWM control and reduced acoustic emissions, making it suitable for gaming systems and demanding builds. The fan’s recognizable be quiet! design provides a clean, minimalist look that integrates well into various configurations.

Advantages

The closed-loop motor enables stable, progressive speed control via PWM, improving cooling responsiveness across different workloads. High-speed operation increases airflow for better heat dissipation while the optimized blade geometry and frame reduce turbulence and noise. The neutral white color and iconic design ensure visual compatibility with a wide range of system styles.

Key specifications

• Size: 140 mm
• Interface: PWM
• Speed class: High-speed
• Color: White
• Motor: Closed-loop speed-regulating motor

How to use

Install the fan in a standard 140 mm mounting position in the case, observing airflow direction indicated on the frame. Connect the PWM cable to a motherboard fan header that supports PWM control to allow automatic speed regulation based on system temperatures. Secure the fan with the supplied screws and verify clear intake and exhaust paths for optimal airflow.

Recommendations

For balanced cooling and noise performance, use the Pure Wings 3 140mm PWM High-Speed White on radiators or as front/rear case fans paired with PWM-capable headers. Regularly clean dust from the blades and frame to maintain performance and lifespan.
