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

The be quiet! Pure Wings 3 140mm PWM White is a case fan designed for efficient and reliable cooling in desktop PCs. It combines a low minimum rpm with a maximum rotational speed of 1200 RPM and delivers an airflow of 97.5 m³/h and an air pressure of 0.96 mmH2O. The fan uses a rifle bearing for increased durability and operates within a voltage range of 5–13.2 V. Its white finish and 140 x 140 x 25 mm dimensions make it suitable for a variety of system builds.

Advantages

The Pure Wings 3 140mm PWM White provides steady airflow and balanced air pressure for case ventilation while keeping noise levels low thanks to its optimized blade design. The rifle bearing enhances lifespan and reliability, and PWM control allows automatic speed adjustment according to system demands. Its standard 140 mm size and white colour enable easy integration into most PC configurations.

How to use

Install the Pure Wings 3 140mm PWM White in a compatible 140 mm fan mount inside the PC case, aligning the airflow direction as needed for intake or exhaust. Connect the fan to a PWM-capable motherboard header or a PWM fan controller using the provided cable to allow automatic speed regulation. Secure the fan with the appropriate screws and ensure cables are routed to avoid contact with the blades.

Recommendations

For optimal performance, use the fan on a PWM header so motherboard or fan controller can adjust speed based on temperature. Regularly clean dust from the blades and fan frame to maintain airflow and cooling efficiency.
