Lian Li SL Infinity LCD Flex 120 Uni Fan ARGB PWM 120mm Black 3 Pack

The Lian Li UNI FAN SL-INF LCD FLEX 120 ARGB Triple Pack is a three fan cooling solution designed to combine effective airflow, customisable LCD displays and distinctive RGB illumination for gaming PCs and enthusiast builds. Each 120mm fan features a 1.8-inch IPS LCD with a 400 x 400 resolution and 60Hz refresh rate, supporting custom videos, GIFs, images and system-monitoring dashboards through L-Connect 3 software. The standard-blade design delivers fan speeds of up to 2000 RPM, airflow of up to 59.2 CFM and static pressure of 2.34 mmH2O, with a maximum noise level of 29.5 dBA per fan. A Fluid Dynamic Bearing supports smooth operation, while the integrated 64 LED ARGB lighting system features three independently controllable zones across the fan blades, infinity mirror sides and frame edges, creating layered lighting effects that complement the sleek black finish. The dual-sided frame features asymmetrical infinity mirror styling, while the LCD FLEX Receiver allows the frame orientation to be adjusted without changing the original connection direction, providing greater installation flexibility and simplifying cable management. PWM fan-speed control, L-Connect 3 software and compatible 5V 3-pin ARGB motherboard synchronisation provide versatile control over cooling performance and lighting. Measuring 120 x 124 x 28mm per fan, this triple pack includes three LCD fans, an LCD FLEX Receiver, a 9-pin USB cable, a 5V 3-pin ARGB cable and a 1-to-3 PWM-to-SATA cable. The L-Wireless Controller is not included and is required separately for wireless control modes. Combining personalised display content, coordinated illumination and flexible installation, the Lian Li UNI FAN SL-INF LCD FLEX 120 ARGB Triple Pack is an excellent choice for creating a refined, high performance PC build.

Important Installation Notice: SL-INF LCD FLEX Receiver

Important: The UNI FAN SL-INF LCD FLEX receiver includes an adaptor that allows the receiver to be installed on either side. Do not install the receiver on one end and the adaptor on the opposite end, as this configuration will result in connection issues. The receiver and adaptor should always be installed together on the same side.

Enhanced Bearing Design

A newly engineered oil retention groove (shown in red) around the fan bearing helps keep lubricant precisely where it’s needed, ensuring consistent lubrication for reduced friction, quieter operation, and long-term bearing reliability.
