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

The Lian Li Uni Fan SL-INF FLex LED Reverse fan 3 pack features three 120mm modular case fans designed to combine high performance cooling with customisable ARGB lighting and a flexible installation system. Featuring a Fluid Dynamic Bearing and optimised aerodynamic design, these fans operate at up to 2200 RPM, delivering up to 65.7 CFM airflow and 2.85 mmH2O static pressure while maintaining a maximum acoustic noise level of 31 dBA. Its dual sided frame incorporates an asymmetrical infinity mirror design with three independently controlled lighting zones across the fan blades, side infinity mirror and frame edge, with 58 LEDs providing detailed illumination. The 120 x 124 x 28mm fan uses PBT and PC construction and supports PWM fan control, motherboard 5V 3-pin ARGB synchronisation and L-Connect 3 software, while the included LED Flex Receiver enables flexible connections and cleaner cable routing. The Flex design allows the fan frame orientation to be changed while maintaining the original connection direction, making it easier to integrate into different case layouts.

Asymmetrical Design, Infinite Depth

The SL-INF FLEX series features a dual-sided frame design, with an angled pattern on one side and a dual-rectangle design on the other. Layered lighting effects create a richer, more dimensional visual experience.

Three Zones, Endless Brilliance

The SL-INF FLEX series features three independently controlled lighting zones, each delivering its own unique visual effect. With dual-sided frame lighting and a central infinity mirror, it creates a full-range RGB showcase from every angle.

• ZONE 1: Fan blades and central hub infinity mirror
• ZONE 2: Outer edges of the dual-side infinity mirrors and side light strips
• ZONE 3: Inner edge of the side infinity mirror

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.

Flexible Control, Your Way

Using the included cables, the FLEX Series supports both L-Connect 3 and motherboard control, giving you the flexibility to choose the control mode that best fits your setup.

Control More, Cable Less

Connect both the 4-Pin PWM and 5V 3-Pin ARGB cables to your motherboard, then pair with the L-Wireless Controller for flexible fan speed and lighting control. 

Note: The L-Wireless Controller is optional for L-Connect 3 software control, but required for Wireless Mode.

Built for Motherboard Sync

Control fan speed and lighting through the motherboard BIOS or motherboard software without a wireless controller. 

Note: The L-Wireless Receiver has a single connection port. Use either the 5V 3-Pin ARGB cable or the USB 2.0 cable.

(MB Software Controls Lighting & Fan Speed).

Longer redesigned cables make routing cleaner and cable management easier.

• FLEX Receiver 5V 3-Pin ARGB Cable - 650mm
• FLEX Receiver USB 2.0 (9-Pin) Cable - 650mm

Engineered for Performance, Built for Cooling

Featuring FDB bearings and an optimised aerodynamic design, the SL-INF FLEX series delivers powerful airflow, high static pressure, and quiet operation, keeping demanding systems cool without compromising acoustics.

One Controller, Complete Control

Driven by 2.4GHz wireless technology, one L-Wireless Controller unifies up to 10 groups of compatible LIAN LI devices through a compact rear I/O USB receiver and dedicated PWM receivers, creating a cleaner, more streamlined wireless ecosystem.

• Wireless Series
• Strimmer Series
• Hydroshift II Series
• Flex Series

Note: Each controller supports up to 10 channels and is compatible with all UNI FAN Wireless Series products, including TL FLEX, SL-INF FLEX, STRIMER WIRELESS, and UNI FAN SL Wireless. Support for additional products will be added in future updates.

Exclusive Software, Complete Customisation

With L-Connect 3, lighting effects and fan curves are fully within your control. Built-in presets and customisable profiles let you fine-tune every detail and create a system that reflects your style.

Custom Device Naming

Customise fan names and drag to rearrange their order, making it easy to build smooth, personalised lighting flows that match your setup.

Visual Identification, Easy Pairing

Pair fans in seconds through L-Connect 3. Quickly locate each fan with Device Finder, or bind all detected devices at once for a faster, smoother setup.
