Product Overview

The Lian Li UNI FAN SL-INF FLEX Standard Blade 120mm 3-Pack Black is built for users who want a combination of strong airflow, premium RGB presentation, and cleaner cable management.

This exact model, 12SLIN1F3B, uses Lian Li’s Standard Blade configuration. Each fan operates from approximately 200 to 2300 RPM and delivers up to 67 CFM airflow with a maximum static pressure of 3.4 mmH₂O. As a result, the standard-blade version offers slightly higher airflow and static pressure than the reverse-blade model.

Furthermore, the SL-INF FLEX features Lian Li’s signature dual Infinity Mirror side lighting, an Infinity Mirror center hub, and three independently controlled ARGB lighting zones. This makes the fan suitable for premium showcase systems where cooling and visual presentation are equally important.

The modular UNI FAN design also helps reduce unnecessary cabling between connected fans. In addition, this 3-pack includes the L-Wireless Controller, LED FLEX Receiver, 5V 3-pin ARGB cable, and 1-to-3 PWM-to-SATA cable.

Finished in Black, this kit is an excellent match for gaming PCs, performance workstations, panoramic cases, and dark-themed custom builds.

Detailed Product Description

The Lian Li UNI FAN SL-INF FLEX Standard Blade 120mm 3-Pack Black (12SLIN1F3B) combines high-performance airflow, strong static pressure, premium ARGB lighting, and Lian Li’s modular fan design in one complete cooling kit.

Designed for performance-focused gaming PCs and premium custom builds, each standard-blade fan operates from approximately 200 to 2300 RPM. At maximum speed, it delivers up to 67 CFM airflow and 3.4 mmH₂O static pressure. Therefore, the Standard Blade version is particularly suitable for configurations where strong airflow and pressure are priorities.

Moreover, Lian Li uses a Fluid Dynamic Bearing (FDB) to provide smooth operation and long-term durability. Maximum rated noise is 29.2 dBA, allowing the fan to maintain a good balance between cooling capability and acoustics.

The SL-INF FLEX also delivers a premium visual experience. Each fan integrates 58 addressable LEDs, three independent lighting zones, illuminated blades, Infinity Mirror side elements, and an Infinity Mirror center hub.

Furthermore, this 3-pack includes the L-Wireless Controller and LED FLEX Receiver. Consequently, users can manage compatible fan and lighting functions through L-Connect 3, while motherboard PWM and 5V 3-pin ARGB control remain available for compatible setups.

Cooling Performance

Up to 2300 RPM

The SL-INF FLEX Standard Blade fan operates between approximately 200 and 2300 RPM.

PWM control allows fan speed to adapt according to system cooling requirements. Therefore, the fans can run slower during lighter workloads while increasing speed during gaming, rendering, or other demanding tasks.

67 CFM Maximum Airflow

Each fan delivers up to 67 CFM airflow.

This makes the SL-INF FLEX suitable for moving substantial volumes of air through gaming PC cases, helping supply cooler air to heat-producing components such as the CPU and graphics card.

3.4 mmH₂O Static Pressure

Maximum static pressure reaches 3.4 mmH₂O.

Higher static pressure helps the fan maintain airflow when air must pass through more restrictive areas, including filtered case panels and other airflow-resistant sections.

29.2 dBA Maximum Noise

The Standard Blade model has a maximum rated acoustic level of 29.2 dBA.

As a result, it combines strong cooling specifications with relatively controlled noise at its rated maximum operating point.

Standard Blade Airflow Design

Unlike the Reverse Blade variant, the Standard Blade SL-INF FLEX uses a conventional airflow orientation.

This configuration is ideal when maximum cooling performance and standard airflow direction are preferred.

It is particularly suitable for:

Rear exhaust positions
Top exhaust configurations
Front intake where the rear side is not visually important
High-airflow gaming PC builds
Multi-fan cooling configurations
Performance-oriented custom PCs

The Standard Blade model also offers slightly stronger official performance specifications than the Reverse Blade version:

Standard Blade:
2300 RPM / 67 CFM / 3.4 mmH₂O

Reverse Blade:
2200 RPM / 65.7 CFM / 2.85 mmH₂O

Therefore, buyers prioritizing maximum airflow and static pressure may prefer the Standard Blade version, while buyers prioritizing visible intake aesthetics may prefer the Reverse Blade version.

Fluid Dynamic Bearing

The Fluid Dynamic Bearing (FDB) supports smooth fan rotation while reducing mechanical friction.

This bearing technology is well suited to gaming PCs and workstations that may operate for extended periods.

Benefits include:

Smooth rotational movement
Reduced mechanical friction
Stable fan operation
Improved long-term reliability
Controlled acoustic performance

Triple-Zone ARGB Lighting

The Lian Li SL-INF FLEX is designed to function as both a cooling component and a major visual element inside a gaming PC.

Each fan features three independently controlled lighting zones, allowing greater customization than conventional single-zone ARGB fans.

Lighting elements include:

Illuminated fan blades
Side frame illumination
Infinity Mirror effects
Edge lighting
Center hub lighting

Furthermore, each fan incorporates 58 LEDs, providing dense illumination and smooth lighting transitions.

Infinity Mirror Design

Lian Li’s signature Infinity Mirror styling creates a layered visual effect that makes the lighting appear deeper than the physical frame.

Infinity Mirror elements are incorporated into the fan’s visual design, including the central hub and side sections.

As a result, the SL-INF FLEX looks especially impressive inside:

Tempered-glass gaming PCs
Panoramic PC cases
Dual-chamber cases
RGB showcase systems
Premium black gaming builds

Modular UNI FAN Design

One of the main advantages of the UNI FAN ecosystem is simplified multi-fan installation.

Compatible fans can connect together rather than requiring completely separate wiring for every fan.

Consequently, builders can achieve:

Reduced cable clutter
Cleaner cable management
Easier multi-fan installation
Cleaner internal presentation
Simplified fan grouping

This is particularly useful for systems using multiple groups of three fans.

L-Wireless Controller

The L-Wireless Controller is included with this 3-pack.

It forms part of Lian Li’s wireless control ecosystem and works with compatible FLEX hardware.

This makes the 3-pack a suitable starting point for users building a new SL-INF FLEX setup because the controller does not need to be purchased separately.

L-Connect 3 Control

The SL-INF FLEX supports Lian Li L-Connect 3 software.

Depending on the connected configuration, L-Connect 3 allows compatible management of:

Fan speed
Fan curves
ARGB lighting
Lighting effects
Lighting synchronization
Fan groups
Device identification
Profiles

Therefore, users can customize both thermal performance and system appearance through a centralized interface.

Motherboard PWM & ARGB Control

Users are not limited to L-Connect 3.

The FLEX platform also supports compatible motherboard integration.

PWM Fan Control

Compatible motherboard PWM headers can be used to manage fan speed.

ARGB Control

A compatible 5V 3-pin ARGB connection allows lighting synchronization with supported motherboard RGB ecosystems.

Therefore, builders have greater flexibility when choosing how the cooling and lighting system is controlled.

Compatibility

Fan Size

120mm class

Physical Dimensions

Control Compatibility

L-Wireless Controller
LED FLEX Receiver
Lian Li L-Connect 3
Compatible motherboard PWM headers
Compatible 5V 3-pin ARGB headers

Recommended Installation Positions

Rear exhaust
Top exhaust
Front intake where supported
Side positions depending on preferred airflow orientation
