be quiet! Pure Wings 3 140mm | PWM Triple Pack ventoinha para caixa de computador 14 cm preto 3 peças

PURE WINGS 3 140mm PWM 3-Pack are three 140 mm case fans designed for balanced airflow and low noise. The pack combines optimized fan frames and redesigned blades to increase air pressure and radiator performance while remaining suitable for general case ventilation. Built with rifle bearing technology, these fans are intended for long-term use in gaming and desktop PC builds.

Advantages

The fans provide a wide operating range with low minimum RPM for quiet idle operation and a high top-end speed when more cooling is required. Frame and blade geometry are tuned to reduce air leakage and turbulence, improving overall airflow and radiator efficiency. The rifle bearing design extends service life, and the black, minimalistic appearance fits most system interiors.

How to use

Install the fans in your PC case or on compatible 140 mm radiators using the supplied screws. Connect each fan to a motherboard fan header or a PWM fan hub to allow speed control via PWM. Ensure correct airflow direction based on your case layout and maintain adequate clearance around the fans for unobstructed intake or exhaust. Regularly clean dust from the blades and frame to preserve performance and quiet operation.

Recommendations

Use these fans for case ventilation or on radiators where moderate airflow with increased static pressure is needed. For optimal results, pair with PWM-capable headers and a fan curve configured in your BIOS or fan controller. Clean periodically and replace if audible noise or irregular operation appears.
