be quiet! Light Wings LX 120mm PWM Reverse White (BL133)

The be quiet! Light Wings LX 120mm PWM Reverse White (BL133) is a high-performance ARGB case fan engineered with reversed blade design for optimal side or bottom intake configurations. This 120mm fan delivers 58.9 CFM airflow at up to 1,700 RPM while maintaining quiet operation at 31 dB(A) maximum noise level.

Reversed Blade Design for Intake Optimization

The unique reversed blade configuration makes this fan ideal for bottom or side intake mounting positions. This design ensures efficient airflow direction into your case while maintaining clean visual aesthetics. The white fan shroud complements modern PC builds, particularly in white-themed or RGB-focused systems.

ARGB Lighting and Customization

Equipped with 16 individually addressable RGB LEDs, the Light Wings LX offers vivid and customizable lighting effects through your motherboard's 3-pin 5V ARGB header. Daisy-chaining support simplifies cable management when using multiple fans, allowing synchronized lighting effects across your entire cooling setup.

Performance Specifications

This 120 x 120 x 25 mm fan utilizes rifle bearing technology for extended lifespan up to 60,000 hours. The 4-pin PWM connector enables dynamic speed regulation from 0 to 1,700 RPM through motherboard software, allowing you to balance cooling performance and acoustic levels based on system demands. With 2.31 mm H2O static pressure and 2.4W power consumption at 12V rated voltage, it provides efficient cooling without excessive power draw.

Quiet Operation Technology

The advanced rifle bearing combined with aerodynamic fan blade design ensures low noise levels even at maximum RPM. Operating within a voltage range of 5V to 13.2V with 0.20A input current, the fan maintains consistent performance while keeping noise output to a minimum.
