Product Overview

The Lian Li UNI FAN SL-INF FLEX Standard Blade 120mm 3-Pack White is designed for PC builders who want a strong balance of cooling performance, advanced ARGB lighting, and clean modular installation.

This exact model, 12SLIN1F3W, belongs to the standard LED SL-INF FLEX range and does not include LCD screens. Lian Li sells the LCD-equipped fans separately under the SL-INF LCD FLEX line.

Each Standard Blade fan operates from approximately 200 to 2300 RPM, delivering up to 67 CFM airflow and 3.4 mmH₂O static pressure. Therefore, it is suitable for performance-focused gaming PCs, custom desktops, and multi-fan airflow configurations. The official 3-pack specification also confirms the L-Wireless Controller is included.

Furthermore, the SL-INF FLEX uses Lian Li’s signature dual Infinity Mirror side lighting, Infinity Mirror hub, and three-zone ARGB control. Consequently, users can create a premium RGB presentation without needing the LCD hardware found on the separate LCD model.

The modular UNI FAN design also helps reduce cable clutter between connected fans. Finished in White, this kit is especially suitable for coordinated white gaming PCs, panoramic cases, creator systems, and premium showcase builds.

Detailed Product Description

The Lian Li UNI FAN SL-INF FLEX Standard Blade 120mm 3-Pack White (12SLIN1F3W) is built for users who want strong cooling performance, premium ARGB aesthetics, and cleaner multi-fan installation in a white gaming PC or custom desktop.

This exact model is the LED / non-LCD Standard Blade version. Each fan runs at approximately 200–2300 RPM, delivers up to 67 CFM airflow, and reaches 3.4 mmH₂O static pressure. Furthermore, Lian Li rates maximum acoustic noise at 29.2 dBA and uses a Fluid Dynamic Bearing (FDB) for smooth, reliable operation.

The SL-INF FLEX also features three independently controlled ARGB lighting zones, dual-sided Infinity Mirror styling, and a central Infinity Mirror hub. In addition, each fan integrates 58 LEDs, giving the lighting more depth and visual detail than a basic ARGB case fan.

Because this is a 3-pack, Lian Li includes the L-Wireless Controller, LED FLEX Receiver, 5V 3-pin ARGB cable, and 1-to-3 PWM-to-SATA cable. Consequently, it works well as the starting point for a new SL-INF FLEX setup.

Cooling Performance

Up to 2300 RPM

The Standard Blade version operates at approximately 200–2300 RPM.

PWM control allows the fan speed to increase under heavier thermal loads and reduce during lighter use. Therefore, the cooling system can balance performance and acoustics depending on system demand.

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 compatible gaming PC cases, helping support cooling around the graphics card, processor, VRMs, and other heat-producing components.

3.4 mmH₂O Static Pressure

Maximum static pressure reaches 3.4 mmH₂O.

Higher static pressure helps maintain airflow through restrictive case panels, filters, and other areas where airflow resistance is greater.

29.2 dBA Acoustic Rating

The Standard Blade model is rated at up to 29.2 dBA.

As a result, it provides strong airflow and static-pressure performance while maintaining a controlled acoustic profile at its rated maximum.

Fluid Dynamic Bearing

The Fluid Dynamic Bearing (FDB) is designed to provide smooth fan rotation and dependable long-term operation.

Lian Li also highlights an enhanced oil-retention design around the bearing to help keep lubricant where it is needed. Consequently, the bearing design aims to reduce friction and maintain consistent performance over time.

Benefits

• Smooth fan operation
• Reduced mechanical friction
• Stable performance across the RPM range
• Better long-term bearing reliability
• Controlled acoustic characteristics

Triple-Zone ARGB Lighting

The SL-INF FLEX uses three independently controlled lighting zones.

These zones cover:

• Fan blade illumination
• Side Infinity Mirror lighting
• Edge lighting effects

Moreover, the fan features dual-sided frame lighting and a central Infinity Mirror for a more dimensional RGB presentation.

Each LED version fan contains 58 LEDs, providing dense and smooth illumination throughout the fan assembly.

Infinity Mirror Design

Lian Li uses an asymmetrical dual-sided frame design on the SL-INF FLEX.

One side features an angled pattern, while the opposite side uses a dual-rectangle design. Therefore, the fan can provide a different visual character depending on the viewing angle and installation orientation.

This makes it particularly suitable for:

• Panoramic cases
• Dual-chamber cases
• Tempered-glass gaming PCs
• White showcase builds
• Premium RGB systems

Modular UNI FAN Design

The UNI FAN architecture is designed to reduce cable clutter in multi-fan installations.

Compatible fans can connect together as a group instead of requiring completely separate wiring for every fan. As a result, builders can achieve:

• Cleaner cable management
• Easier installation
• Fewer visible cables
• Simpler fan grouping
• Cleaner showcase presentation

Furthermore, the FLEX Receiver adds more installation flexibility by allowing the frame orientation to be changed while maintaining the intended connection direction.

L-Wireless Controller & FLEX Receiver

This exact 12SLIN1F3W 3-pack includes the L-Wireless Controller.

The package also includes an LED FLEX Receiver, allowing the fan group to integrate with Lian Li’s control ecosystem.

The L-Wireless platform uses 2.4GHz wireless technology, and Lian Li states that one controller can manage up to 10 groups of compatible devices.

L-Connect 3 Control

The SL-INF FLEX supports Lian Li L-Connect 3 for compatible fan and lighting management.

Depending on the setup, users can control:

• Fan speed
• Fan curves
• ARGB effects
• Lighting zones
• Lighting synchronization
• Device groups

In addition, the fan can work with motherboard control when preferred.

Motherboard PWM & ARGB Control

The FLEX Series supports both L-Connect 3 and motherboard-based control.

PWM Fan Control

Connect the fan setup to a compatible 4-pin PWM header to manage fan speed through the motherboard BIOS or supported software.

ARGB Lighting Control

Use the included 5V 3-pin ARGB cable to synchronize lighting with a compatible motherboard RGB ecosystem.

Therefore, users are not locked into a single control method.

Compatibility

Fan Size

120mm class

Physical Dimensions

120 × 124 × 28 mm

Because the frame is slightly larger and thicker than a conventional 120 × 120 × 25mm case fan, verify case clearance before installation.

Supported Control Methods

• L-Wireless Controller
• LED FLEX Receiver
• Lian Li L-Connect 3
• Compatible 4-pin PWM motherboard control
• Compatible 5V 3-pin ARGB motherboard synchronization

Recommended Installation Positions

• Rear exhaust
• Top exhaust
• Front intake where supported
• Side positions depending on airflow orientation
• Multi-fan case mounts

Suitable Case Types

• ATX gaming cases
• Panoramic PC cases
• Dual-chamber cases
• Tempered-glass cases
• High-airflow cases
• Premium white custom PC enclosures

Always verify the specific PC case fan mounting locations and clearance before installation.

Standard Blade vs Reverse Blade

The Standard Blade version offers slightly stronger official cooling specifications than the Reverse Blade version.

The Standard Blade model is ideal for conventional airflow layouts and users prioritizing maximum official airflow and pressure. Meanwhile, the Reverse Blade model is better suited to visible intake positions where maintaining the clean illuminated side is the priority.
