Lian Li UNI FAN SL-INF FLEX Reverse Blade Case Fan with L-Wireless Controller, 120mm ARGB PWM, 2200 RPM, 65.7 CFM, Fluid Dynamic Bearing, PBT/PC, 3-Pack, White | 12RSLIN1F3W

Product Overview

The Lian Li UNI FAN SL-INF FLEX Reverse Blade 120mm White 3-Pack is designed for PC builders who want strong cooling performance without compromising the appearance of a premium tempered-glass system.

This exact model, 12RSLIN1F3W, combines three 120mm reverse-blade fans with Lian Li’s modular UNI FAN design. The reverse blade configuration is especially useful for side and bottom intake positions because it allows the visually attractive side of the fan to face the interior while still drawing fresh air into the case.

Each fan operates at approximately 200–2200 RPM and delivers up to 65.7 CFM airflow with 2.85 mmH₂O static pressure. Therefore, the fan kit provides a strong balance between airflow, pressure, and visual presentation. Lian Li also uses a Fluid Dynamic Bearing, helping provide smooth operation and long-term reliability.

Furthermore, the SL-INF FLEX features Lian Li’s signature Infinity Mirror aesthetic with three lighting zones across the fan blade, side mirror, and edge lighting. The included L-Wireless Controller works with Lian Li’s FLEX ecosystem and L-Connect 3 for compatible lighting and fan-control functions.

Key Features

Reverse Blade Intake Design

The reverse-blade configuration allows the attractive illuminated side of the fan to remain visible when installed as an intake fan. As a result, it is ideal for premium panoramic and dual-chamber PC cases.

Detailed Product Description

The Lian Li UNI FAN SL-INF FLEX Reverse Blade 120mm 3-Pack White (12RSLIN1F3W) is designed for premium gaming PCs, panoramic cases, and custom systems where both airflow and appearance matter.

Unlike a standard intake fan, the reverse-blade design allows the visually attractive illuminated side to remain visible while the fan draws fresh air into the case. Therefore, it is especially useful for bottom and side intake positions in tempered-glass PC builds.

Each fan operates from approximately 200 to 2200 RPM and delivers up to 65.7 CFM airflow with a maximum static pressure of 2.85 mmH₂O. Furthermore, Lian Li uses a Fluid Dynamic Bearing (FDB) to support smooth rotation, reduced friction, and reliable long-term operation.

The SL-INF FLEX also focuses heavily on presentation. It combines Lian Li’s signature dual Infinity Mirror side lighting with an Infinity Mirror center hub and triple-zone ARGB control. As a result, builders can create a more sophisticated lighting setup than with conventional single-zone RGB case fans.

In addition, this three-pack includes the L-Wireless Controller, LED FLEX Receiver, 5V 3-pin ARGB cable, and PWM-to-SATA cable. Consequently, the kit can serve as the foundation for a clean and flexible SL-INF FLEX cooling setup.

Reverse Blade Cooling Performance

The reverse-blade version is engineered primarily for intake-oriented configurations.

Fan Speed

200–2200 RPM

The wide PWM speed range allows the fans to operate at lower speeds during light workloads and increase airflow when additional cooling is required.

Maximum Airflow

65.7 CFM per fan

This airflow rating makes the SL-INF FLEX suitable for supplying fresh air to high-performance gaming PCs, graphics cards, processors, and other heat-producing components.

Maximum Static Pressure

2.85 mmH₂O

The available static pressure helps the fan maintain airflow through restrictive intake panels and filtered case ventilation areas.

Acoustic Noise

Up to 31 dBA

Lian Li officially rates the reverse-blade SL-INF FLEX at up to 31 dBA. Therefore, the fan is designed to balance high-speed cooling with controlled acoustics.

Fluid Dynamic Bearing Design

Each SL-INF FLEX Reverse Blade fan uses a Fluid Dynamic Bearing (FDB).

The bearing system is designed to support smooth rotational movement and reliable long-term operation. In addition, reduced mechanical friction can help maintain stable fan behavior across different RPM levels.

For gaming PCs that operate for long periods, this bearing design makes the SL-INF FLEX more suitable than basic entry-level sleeve-bearing fans.

Triple-Zone ARGB Lighting

The SL-INF FLEX combines cooling performance with advanced RGB presentation.

Lian Li integrates:

• Illuminated fan blades
• Infinity Mirror center hub
• Dual Infinity Mirror side lighting
• Triple-zone ARGB control
• 58 LEDs per fan

The three lighting zones can be controlled independently through supported Lian Li software. Therefore, users can create layered lighting effects instead of applying one identical RGB effect across the entire fan.

Infinity Mirror Design

The SL-INF FLEX continues the signature visual identity of Lian Li’s SL-Infinity series.

Both sides of the fan frame incorporate Infinity Mirror lighting elements, while the center hub also uses an Infinity Mirror effect. Furthermore, the two side mirror designs are intentionally different, adding more visual variety depending on the viewing angle.

This makes the fan particularly suitable for:

• Panoramic PC cases
• Dual-chamber cases
• Glass-sided gaming PCs
• White showcase builds
• Custom RGB systems

FLEX Receiver & L-Wireless Control

The new FLEX Receiver gives users several ways to control the fan.

L-Wireless Control

When used with the included L-Wireless Controller, the FLEX Receiver supports compatible wireless control through L-Connect 3.

Motherboard PWM Control

Fan speed can also be controlled directly through a compatible motherboard PWM header.

Motherboard ARGB Control

The included 5V 3-pin ARGB cable allows lighting synchronization through compatible motherboard RGB software.

Therefore, users can choose between:

• Lian Li L-Wireless control
• L-Connect 3
• Motherboard PWM control
• Motherboard ARGB lighting control

This flexibility is one of the biggest differences between the FLEX generation and older UNI FAN implementations.

Modular UNI FAN Installation

Lian Li’s UNI FAN architecture is designed to reduce unnecessary cabling inside the PC.

Multiple compatible fans can connect together as a group, reducing the need for separate power and lighting cables for every fan.

As a result, builders benefit from:

• Cleaner cable management
• Easier multi-fan installation
• Less visible wiring
• Cleaner showcase builds
• Easier fan-group management

This is especially useful in systems using six, nine, or more case fans.

Compatibility

The Lian Li UNI FAN SL-INF FLEX Reverse Blade uses a 120mm-class mounting format.

Fan Dimensions

120 × 124 × 28 mm

Because the frame is slightly larger and thicker than a basic 120 × 120 × 25mm case fan, always check available case clearance before installation.
