Overview

A 140mm PWM ARGB fan featuring second-generation blade design, 40 addressable LEDs with infinity mirror lighting, and a single 7-pin cable for power and lighting. Suitable for radiators and case cooling in custom PC builds.

Second-Generation Cooling Performance

The updated seven-blade design delivers a 10 percent performance increase over the previous SL140 model. Maximum airflow reaches 72.7 CFM with 2.88 mmH2O static pressure while noise stays at 28 dBA. PWM control allows speeds from 200 to 1600 RPM, and L-Connect 3 software supports a start-stop mode that halts the fan below 50°C.

ARGB Lighting and Infinity Mirror

Forty digitally addressable RGB LEDs sit in the frame and central hub behind a layered infinity mirror with 0.5 mm gaps for a 3D effect visible from any angle. Aluminum trim reflects light onto the frame edges and sides. Over 30 effects and 16.8 million colors are configurable per cluster via L-Connect 3 or motherboard software.

Simplified Connectivity and Cable Management

A single 7-pin cable replaces separate power and lighting wires, connecting to the UNI HUB or the included split cable with 4-pin PWM and 3-pin ARGB headers for direct motherboard connection. The daisy-chain key twists off for radiator clearance and reattaches easily. The smaller cable module sits centrally on the frame edge and rotates for routing flexibility.

UNI HUB and Software Control

The UNI HUB supports up to sixteen fans in four clusters plus two dedicated 3-pin ARGB ports for other Lian Li devices. L-Connect 3 assigns fan curves, start-stop behavior, and lighting effects to each cluster independently, enabling synchronized lighting shows across the build.
