Be Quiet! Light Wings LX 140mm PWM High-Speed ARGB Fan

The Light Wings LX 140mm PWM high-speed combines performance-focused engineering with addressable RGB lighting. Designed for system builders requiring both effective cooling and customizable aesthetics, this 140mm fan delivers 75.3 CFM airflow at 1800 RPM while maintaining 30.5 dB(A) noise levels.

Performance Features

Equipped with 9 optimized fan blades engineered at precise angles, the Light Wings LX generates 2.45 mm H2O static pressure for effective airflow through restrictive components like radiators and heatsinks. The innovative closed-loop motor maintains consistent RPM regardless of resistance, ensuring stable performance across varying system configurations. The rifle bearing design provides an operational lifetime of up to 60,000 hours at 25°C.

ARGB Lighting System

The illuminated hub and frosted fan blades create distinct lighting effects through 16 individually addressable LEDs. The 5V ARGB connector includes daisy chain capability for synchronized multi-fan setups. Multiple color modes and patterns allow customization to match your system's aesthetic through compatible motherboard software or ARGB controllers.
