## Summary description

Lian Li UNI FAN SL-INF 120 is a 120mm ARGB reverse-blade PWM case fan sold as a pack of three single fans without a controller.

Suitable for intake, exhaust or radiator use in gaming and workstation systems.

## Long description

The Lian Li UNI FAN SL-INF 120 ARGB Reverse Blade PWM Fan — 3× Single Pack (no controller), black is a set of three 120mm case fans engineered for PC cooling with addressable RGB lighting and PWM speed control. Each fan uses a reverse-blade design intended to influence airflow characteristics, while ARGB LEDs provide customizable lighting effects when connected to a compatible header or controller. Sold as three individual fans without a controller, this pack is intended for builders who already have or plan to use a motherboard or external controller to manage lighting and fan speed.
Advantages
These 120mm fans combine PWM control for precise speed and noise management with addressable RGB lighting for per-fan illumination. The reverse-blade geometry aims to modify airflow and acoustic profile compared with conventional blade shapes. The fans are designed for easy installation into standard 120mm mounting points and can be chained or connected to compatible hubs or headers for synchronized lighting. Supplied as single fans in a three-piece pack, they offer flexibility for partial or complete cooling upgrades.
Suitable for
PC case cooling — intake and exhaust in mid-tower and full-tower systems
Radiator or AIO liquid cooler mounting where 120mm fans are supported
Builds that use motherboard ARGB headers or third-party controllers for lighting synchronization
Users replacing or upgrading stock fans with a focus on adjustable speed and lighting
When it may not be suitable
This pack does not include a dedicated controller, so it is not suitable for users who lack a motherboard or external controller with addressable RGB support unless they plan to purchase a compatible controller separately. The reverse-blade design may produce airflow and sound characteristics different from conventional fan blades; users seeking a specific acoustic signature should compare performance data before purchase.
Key specifications
Size: 120 mm frame compatible with standard 120 mm mounts
Control type: PWM speed control for automatic fan speed adjustment via motherboard or controller
Lighting: Addressable RGB (ARGB) LEDs per fan for customizable lighting effects
Mounting: Four-point screw mounting for case or radiator installation
Design: Reverse-blade impeller geometry
Pack contents: Three individual 120 mm fans supplied without a controller
How to use
Install each fan into a 120 mm mounting location in your case or on a compatible radiator using the provided screws. Connect the PWM power connector to a motherboard fan header or PWM-capable fan controller to enable automatic speed regulation. Connect the ARGB cable to a compatible addressable RGB header or controller to enable lighting control; follow the motherboard or controller manual for pin orientation and software setup. Arrange fan airflow directions consistently for intake or exhaust according to your case layout and testing for optimal thermal performance.
What to consider before purchase
Whether your motherboard or existing controller supports addressable RGB headers and PWM fan control
Compatibility of fan dimensions and mounting with your case or radiator
Acoustic preferences, since reverse-blade geometry may affect noise and airflow characteristics
Requirement to purchase an external ARGB controller if your system lacks a compatible header
Usage recommendations
For balanced cooling and quiet operation, configure PWM curves in BIOS or fan-control software to match typical system loads, and place fans in a consistent intake/exhaust arrangement. When using ARGB lighting, verify header pinouts before connection to avoid damage, and chain fans only according to the controller’s supported power limits.
