Product Overview

LIAN LI UNI FAN SL-INF LCD FLEX 120mm ARGB PWM Fan

The LIAN LI UNI FAN SL-INF LCD FLEX 120mm ARGB PWM Fan combines exceptional cooling performance with immersive multi-zone lighting, delivering powerful airflow alongside a fully programmable 1.8-inch LCD display. Designed for enthusiasts looking to maximise thermal performance without compromising visual impact, it pairs high-performance cooling with a distinctive dual-sided frame design, allowing users to personalise their system with custom graphics, animated content, system monitoring information, and unique visual themes while retaining the signature SL-INF infinity mirror aesthetic.

Built with durable PBT fan blades, a robust PC housing, and precision Fluid Dynamic Bearing technology, the SL-INF LCD FLEX is engineered to deliver dependable cooling and long-term reliability. Flexible motherboard and L-Connect 3 control options, wireless ecosystem support, independently controlled ARGB lighting zones, and an upgraded LCD display make it an ideal choice for builders seeking premium aesthetics, powerful airflow, and extensive system customisation.


Personalised LCD Displays with Exceptional Clarity

At the centre of the SL-INF LCD FLEX is a newly designed 1.8-inch LCD display featuring a crisp 400 x 400 resolution, a smooth 60Hz refresh rate, and a refined narrow-bezel design that maximises the visible display area. Through L-Connect 3, users can personalise the display with custom MP4 videos, GIFs, JPG and PNG images, live system monitoring dashboards, animated overlays, or one of 29 built-in wireless display themes, creating a truly unique centrepiece for any PC build.


Three-Zone ARGB Lighting with Infinite Depth

The SL-INF LCD FLEX features an advanced three-zone ARGB lighting system that creates a rich, multidimensional lighting experience from every angle. Illuminated fan blades and the central infinity mirror are complemented by dual-sided frame lighting and layered infinity mirror effects, allowing each lighting zone to be independently controlled for highly personalised lighting effects that enhance the appearance of any modern RGB build while perfectly complementing the integrated LCD display.


Engineered for Performance, Built for Cooling

Featuring precision Fluid Dynamic Bearings and an optimised aerodynamic blade design, the SL-INF LCD FLEX is built to deliver powerful airflow, high static pressure, and quiet operation. Operating at speeds of up to 2000 RPM, it produces up to 59.2 CFM of airflow and 2.34 mmH2O of static pressure, providing excellent cooling performance for PC cases and radiators while maintaining a low maximum noise level of just 29.5 dBA.


Flexible Control with L-Connect 3 and Motherboard Synchronisation

The SL-INF LCD FLEX provides multiple control options to suit different build preferences. Using the included cables, users can control fan speed, lighting, and LCD functionality through L-Connect 3 or directly through compatible motherboard software and BIOS. LCD themes can be configured through USB mode before switching to motherboard ARGB synchronisation, while the optional L-Wireless Controller enables Wireless Mode with access to built-in LCD themes and streamlined device management.


Smarter Connectivity with the LIAN LI Wireless Ecosystem

Designed as part of the UNI FAN Wireless ecosystem, the SL-INF LCD FLEX supports centralised management through a single optional L-Wireless Controller capable of controlling up to ten groups of compatible LIAN LI devices. Custom device naming, simplified pairing, visual device identification, and flexible lighting profiles allow builders to create coordinated cooling and lighting effects while reducing cable clutter through redesigned, longer cables that simplify routing.


Premium Engineering for Long-Term Reliability

Constructed using durable PBT fan blades, a robust PC frame, and precision Fluid Dynamic Bearings, the SL-INF LCD FLEX is engineered to deliver dependable cooling performance and long-term stability. Its premium materials and refined construction help minimise vibration while ensuring consistent airflow and reliable operation throughout extended periods of use.

The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Watercooling for the PC has been around for years in some form or another, for at least as long as Scan have been in business, with basic physics defining why you want to use it. That means for air cooling, to cope with increasing temperature in the heatsink you need to move the air across it faster. That is why thermostatically controlled fans in your PC will turn faster the hotter something gets.
