be quiet! Light Wings LX PWM ARGB Fan, Rifle Bearing, 140mm, Black

This 140 mm high-speed cooling fan is engineered for efficient thermal management in computer systems, providing a maximum rotational speed of 1800 RPM. It achieves an airflow rate of 75.3 CFM and generates a static pressure of 2.45 mmH2O, making it suitable for both general case ventilation and demanding radiator installations. The design incorporates nine optimized fan blades to manage the high performance output while maintaining specified operational acoustics.

Acoustic performance peaks at 30.5 dB under maximum load, facilitated by the durable Rifle bearing technology, which contributes to a Mean Time To Failure (MTTF) rating of 60,000 hours. Integration into modern systems is streamlined via 4-pin PWM control, allowing the motherboard to precisely adjust speed based on temperature input. The fan integrates ARGB illumination via 16 LEDs, utilizing a 5V 3-pin connector that supports daisy-chain functionality for lighting synchronization.

The unit measures 140 mm in width and depth with a 25 mm thickness, conforming to standard chassis and heatsink specifications. It operates within a voltage range of 5 V to 13.2 V and draws a rated current of 0.18 A for the fan motor. Mounting hardware and screws are included, ensuring installation compatibility across various cooling configurations.
