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

This 140 mm cooling fan is designed for efficient chassis cooling applications, utilizing focused airflow and reliable static pressure performance. The fan operates across a controlled rotational range, adjusting from 200 RPM up to a maximum of 1600 RPM, governed by integrated PWM support. At peak operational speed, the unit delivers 72.7 CFM of airflow while generating a static pressure rating of 2.88 mmH2O. Operational stability and reduced friction noise are achieved through the implementation of a Fluid Dynamic Bearing (FDB) mechanism.

Physical specifications include dimensions of 140 mm by 142 mm with a 25 mm depth. The fan integrates an Infinity RGB illumination system, featuring 40 LEDs for visual customization. Connectivity is streamlined through a combined cable system that utilizes a 4-PIN PWM connector for speed control and a separate 3-PIN ARGB connector for lighting power and synchronization. The unit requires 12V DC for the fan motor and 5V DC for the lighting circuit, with the total fan power consumption measured at 4.56 W.
