Product Overview

The Lian Li UNI FAN SL-INF FLEX 120 Reverse Blade Black 3-Pack (12RSLIN1F3B) is a premium modular cooling solution designed for gaming PCs, panoramic cases and high-end RGB showcase builds. This reverse-blade version delivers intake airflow while allowing the visually attractive side of the fan to remain facing into the case, making it especially useful for side and bottom intake configurations.

Each 120mm fan operates at up to 2200 RPM and delivers up to 65.7 CFM airflow with 2.85 mmH₂O static pressure. In addition, Fluid Dynamic Bearings help provide smooth and reliable operation.

The SL-INF FLEX series goes beyond cooling with LIAN LI’s signature Infinity Mirror styling and three-zone ARGB illumination. Moreover, the included L-Wireless Controller provides flexible lighting and fan management, while L-Connect 3 and motherboard synchronization provide additional control options.

Key Features

Reverse Blade for Cleaner Intake Builds

The reverse-blade configuration changes the airflow direction while preserving the attractive illuminated side of the fan inside the case.

As a result, builders can create side or bottom intake configurations without exposing the conventional rear support structure of a standard fan.

This is particularly useful in panoramic and dual-chamber gaming cases where the fans form an important part of the finished build.

Signature Infinity Mirror Design

The SL-INF FLEX combines its illuminated fan blades with Infinity Mirror effects at the hub and sides. LIAN LI also uses an asymmetrical dual-sided frame design to add more visual depth to the lighting system.

Three-Zone ARGB Lighting

Three individually styled lighting areas create a layered RGB appearance across the:

Fan blades • Side Infinity Mirror • Edge lighting

The non-LCD SL-INF FLEX uses 58 LEDs per fan, providing extensive illumination for showcase PC builds.

Up to 2200 RPM

The reverse-blade SL-INF FLEX operates across a 0 / 200–2200 RPM speed range.

Therefore, users can balance airflow, cooling performance and acoustics according to their PC configuration.

65.7 CFM Airflow

Each reverse-blade fan can deliver up to 65.7 CFM, making the SL-INF FLEX suitable for airflow-focused gaming and enthusiast systems while maintaining its showcase-oriented design.

2.85 mmH₂O Static Pressure

With static pressure rated up to 2.85 mmH₂O, the reverse-blade model provides useful pressure performance for modern cooling configurations.

Fluid Dynamic Bearing

LIAN LI equips the SL-INF FLEX with a Fluid Dynamic Bearing (FDB).

The bearing design supports smooth fan operation and long-term reliability while helping the fan maintain consistent performance.

Modular Multi-Fan Design

UNI FAN’s modular architecture allows multiple fans to form a cleaner fan cluster, helping reduce the number of individual cables required compared with installing completely independent conventional fans.

Consequently, cable management becomes easier, especially in systems using several RGB fans.

L-Wireless Controller Included

The 12RSLIN1F3B 3-pack includes an L-Wireless Controller, providing access to LIAN LI’s flexible wireless control ecosystem.

The package also includes the required FLEX receiver and connection accessories.

L-Connect 3 Support

Users can manage compatible fan and lighting functions through LIAN LI L-Connect 3.

Alternatively, the FLEX platform supports motherboard ARGB synchronization and PWM fan control for builders who prefer motherboard-based management.

Why Choose the Lian Li UNI FAN SL-INF FLEX Reverse Blade?

The SL-INF FLEX Reverse Blade is designed for builders who want premium cooling without compromising the visual presentation of intake fans.

Traditional intake installations often expose the rear frame of the fan. In contrast, the reverse-blade design allows the attractive Infinity Mirror and RGB side to remain visible while the fan draws fresh air into the chassis.

Furthermore, the three-pack combines three premium ARGB fans, modular connectivity and an included L-Wireless Controller, making it particularly suitable for modern panoramic gaming cases and high-end custom PCs.
