120mm Lian Li UNI FAN SL-INF 120 ARGB Reverse Blade PWM Fan Kit, 6-Pack with Controller, Black

The 120mm Lian Li UNI FAN SL-INF 120 ARGB Reverse Blade PWM Fan Kit is a six-pack of reverse-blade case fans designed for coordinated airflow and lighting in PC builds. Each fan includes addressable RGB (ARGB) lighting and PWM speed control, and the kit is supplied with a controller to manage fan speed and lighting effects. The black finish and standardized 120mm mounting make the kit suitable for typical chassis and radiator installations where synchronized performance and illumination are needed.

Advantages

The kit combines six matched 120mm fans with integrated ARGB lighting and PWM control under a single controller, enabling synchronized fan curves and lighting effects across multiple positions. Reverse-blade geometry is intended to influence airflow characteristics and noise profile, while PWM support allows automatic speed adjustment based on system temperature. The included controller reduces the need for multiple motherboard headers and simplifies cable management in multi-fan configurations.

Suitable for

• Chassis cooling with multiple intake and exhaust fan positions
• Radiator or AIO mounting that accepts 120mm fans
• PC builds that require synchronized ARGB lighting across several fans
• Systems where centralized PWM control is preferred over many individual motherboard headers

When it may not be suitable

This 6-pack is sized for standard 120mm mounting and may be excessive for very small cases that only accept one or two fans. If a build requires different fan sizes (for example, 140mm) or a single-fan replacement, this multi-fan kit may not be the most practical choice. Additionally, exact noise and airflow performance will depend on case layout and fan placement, so results can vary between systems.

Key specifications

• Fan size: 120 mm standard mounting
• Quantity: 6 fans plus a dedicated controller
• Lighting: Addressable RGB (ARGB) per fan for individual lighting control
• Speed control: PWM support for automatic fan speed modulation
• Color/finish: Black frame and blades

How to use

Install each fan into the chassis or radiator using the standard 120mm mounting points. Connect the fans to the supplied controller following the manufacturer's wiring layout, then connect the controller to the system power and any desired ARGB or PWM headers if supported. Use motherboard software or the controller's interface to configure PWM curves and ARGB lighting effects; if no motherboard headers are available, the controller can centralize power and lighting control. Verify airflow direction after installation and adjust fan orientation for optimal intake or exhaust as required.

What to consider before purchase

• Confirm your case or radiator supports 120mm fans and has space for up to six units if you plan full-kit use
• Check motherboard or controller compatibility for ARGB and PWM connections
• Consider overall cooling needs and whether reverse-blade fans match your desired airflow and noise profile
• Ensure you have available internal power connectors or plan to use the included controller for centralized connections

Usage recommendations

For balanced cooling and noise, configure a combination of intake and exhaust positions rather than running all six fans in one direction. Use PWM profiles tied to CPU or GPU temperature to ensure the fans increase speed only when needed, and synchronize ARGB lighting through the controller or motherboard software for consistent illumination across the build.
