Lian Li UNI FAN SL-INF LCD Flex 120 mm Black

120 mm LCD Case Fan

The Lian Li UNI FAN SL-INF LCD Flex is a 120 mm case fan with an integrated 1.8-inch 400 x 400 60 Hz LCD screen. It targets builders who want real-time system monitoring or custom visuals directly on the fan frame. The single-fan pack ships without a controller, relying on motherboard PWM or L-Connect 3 software for operation. Its normal-blade design pushes air in the standard direction for typical case intake or exhaust roles.

Upgrade from basic RGB fans

This model replaces standard ARGB fans that lack a display, adding a 1.8-inch screen for temperatures, usage graphs or personal images. The jump is worth it when the builder values at-a-glance hardware data or unique aesthetics over simpler lighting. Buyers who only need airflow and basic colour sync will not benefit from the extra cost and software setup. The fan also lacks a reverse-blade variant, so it cannot serve as a push-pull pair without a matching normal-blade unit.

Build integration and requirements

The fan connects via a 4-pin PWM header and a 3-pin ARGB header on the motherboard, or through L-Connect 3 using a compatible Lian Li wireless receiver. No dedicated controller is bundled, so an existing UNI FAN ecosystem or motherboard control is required. The LCD panel draws power through the same cables, keeping cable count low. Builders needing a starter kit with a hub and multiple fans should look elsewhere, as this is a single expansion unit.
