Lian Li UNI FAN SL-INF Reverse Blade, 140mm, PWM, Fluid Dynamic Bearing, ARGB Fan, Black

This 140mm reverse blade case fan is engineered for system configurations where air intake is necessary without sacrificing the desired aesthetic facing the viewer. The fan operates across a controllable speed range, capable of reaching a maximum rotational speed of 1600 RPM while maintaining thermal efficiency. It delivers a maximum airflow of 72.7 CFM coupled with a static pressure output of 2.95 mmH2O, suitable for general case ventilation and specific application on denser cooling apparatuses like radiators. The unit utilizes a 4-pin connector that supports Pulse Width Modulation (PWM), enabling dynamic speed adjustments based on real-time system temperature feedback.

Stability and operational longevity are addressed through the implementation of a Fluid Dynamic Bearing (FDB) system, contributing to a high Mean Time To Failure (MTTF) rating of 70,000 hours. The construction combines plastic and aluminum elements, designed for durability within standard PC case environments. At its maximum speed, the fan unit generates a recorded noise output of 28 dB. Illumination is provided by integrated Addressable RGB (ARGB) lighting, which requires connectivity to a separate 5-volt power source for full functionality.
