be quiet! Pure Wings 3 120 PWM (BL105)

be quiet! Pure Wings 3 120 PWM (BL105) is a 120×120×25 mm case fan featuring 4-pin PWM control, designed for installation in standard PC case mounting points and all-in-one CPU coolers. The fan is equipped with 7 optimized blades for efficient airflow and an updated exit frame geometry that reduces edge vortices and improves performance under resistance, such as when filtering dust or working across radiator fins. At 100% PWM on 12 V, the fan spins up to 1600 RPM, delivering 49.9 CFM (84.8 m³/h) of airflow and 1.45 mm H₂O of static pressure while maintaining a noise level of 25.5 dB(A). Inside, it employs a rifle bearing and 4-pole motor, ensuring stable operation across a wide speed range and reliability for extended use in demanding systems. Electrical specifications include a rated voltage of 12 V DC, operating range of 5–13.2 V, current draw of 0.10 A, and power consumption of 2.4 W. The fan comes with a 460 mm cable and 4 mounting screws. be quiet! Pure Wings 3 120 PWM (BL105) is ideal both for quiet case airflow and for builds requiring an optimal balance of low noise and sufficient static pressure for radiators or dense grilles.
