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

The Lian Li UNI FAN SL-INF FLEX LCD 120 3 pack features three 120mm reverse blade case fans that combines high performance airflow, customisable LCD visuals and detailed ARGB lighting in a flexible modular design. The integrated 1.6 inch IPS LCD features a 400 x 400 resolution, 500-nit brightness and 24-bit colour depth, supporting custom images, GIFs and system information through L-Connect 3. The fan uses a Fluid Dynamic Bearing and operates at up to 1950 RPM, producing up to 56.89 CFM airflow and 2.28 mmH2O static pressure with a maximum noise level of 31 dBA. Its dual-sided lighting design incorporates 64 LEDs across three independently controllable zones, including the fan blades, side infinity mirror and frame edge, while the 120 x 124 x 28mm frame provides a distinctive infinity-mirror appearance from either side. The FLEX mechanism allows the fan frame to be reconfigured while retaining the same connection direction, helping simplify installation in different orientations and case layouts, while the reverse-blade design is suited to configurations where the visible side of the fan is used as the intake. PWM control, 5V 3-pin ARGB synchronisation and L-Connect 3 software support provide flexible control over fan performance, lighting and LCD content, making the UNI FAN SL-INF FLEX LCD 120 an adaptable choice for showcase gaming PCs and custom builds.

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.
