Lian Li Uni Fan SL140 PWM ARGB Fan, Fluid Dynamic Bearing, 140mm, White

This 140mm cooling fan is engineered to provide focused airflow and efficient thermal dissipation within a computer chassis. The unit features a rotational speed range of 500 RPM minimum to 1500 RPM maximum, controlled via a 4-pin PWM connection. At peak operation, the fan moves 70.5 CFM of air, generating a static pressure rating of 1.67 mmH2O. Operational noise is contained at a maximum level of 30 dB, supporting system requirements for performance and low acoustic output.

The fan utilizes a Fluid Dynamic Bearing (FDB) system, contributing to increased stability and extended service life under continuous operation. A distinguishing characteristic of this model is its interlocking frame design, which allows multiple units to be connected directly, simplifying cable management and routing requirements. Illumination is provided by 32 addressable RGB LEDs, manageable through external control systems via a 3-pin ARGB signal connector. The overall structure and fins incorporate aluminum materials.
