Single 120 mm ARGB case fan with 1.8-inch LCD

This Lian Li UNI FAN SL-INF LCD Flex is a single white 120 mm case fan that integrates a 1.8-inch LCD display for real-time monitoring and custom visuals. It uses a normal-blade design and ships without a controller, so the buyer must provide one separately. The fan targets builders who want per-fan LCD personalisation inside a standard 120 mm mounting point. ||

LCD visuals and multi-zone lighting via USB 9-pin

When the USB 9-pin cable is connected to the LCD Flex receiver, L-Connect 3 unlocks full LCD functionality including video and photo uploads at 400 x 400 resolution and 60 Hz refresh. Multi-zone ARGB edge lighting adds depth, while PWM and ARGB motherboard sync remain available for basic control without software. ||

Flexible receiver platform for mixed control schemes

The Flex series receiver platform lets the fan operate through USB, L-Wireless or direct motherboard PWM and ARGB headers, fitting builds that prefer software customisation, wireless control or pure header synchronisation. Because no controller is included, buyers who want multi-fan daisy-chaining or centralised hub management must source a compatible Lian Li controller separately. This fan does not suit builders seeking a reverse-blade variant or an all-in-one kit with controller included.

Questions about this item

How do I install the 120 mm fan and what step is often missed?

Mount the fan using the four screw holes, then connect the PWM and ARGB cables to the motherboard headers; the step many miss is plugging the USB 9-pin cable into the LCD Flex receiver so the 1.8-inch 400 x 400 60Hz LCD unlocks full customisation in L-Connect 3.

What maintenance will this fan need later?

Periodically remove dust from the blades and frame with compressed air; the LCD surface can be wiped gently with a microfibre cloth, and no lubrication or bearing service is required.

What limit appears first during sustained use?

The 1.8-inch LCD is rated for 60 Hz refresh, so continuous high-frame-rate video playback may hit the panel's refresh ceiling before the fan's airflow performance becomes a constraint.
