## Summary description

The Lian Li UNI FAN SL-INF 140 is a 140 mm ARGB PWM case fan supplied as a 3-fan single pack in white. It features reverse-blade design and PWM speed control for efficient airflow and quieter operation. Sold without a controller, the fans are designed for PC cooling, radiator mounting and customizable ARGB lighting when connected to compatible motherboard or controller.

## Long description

The Lian Li UNI FAN SL-INF 140 ARGB Reverse Blade PWM fan is a 140 mm case fan sold as a three-piece single pack in white and supplied without a controller. Its reverse-blade design and PWM speed control are intended to balance airflow and acoustic performance. The fans include addressable RGB lighting that can be customized when connected to a compatible motherboard or separate ARGB controller. The pack is suitable for system case cooling and radiator mounting in desktop PC builds where coordinated fan aesthetics and variable speed control are required.
Advantages
The reverse-blade profile improves static pressure for use on radiators and tight fin stacks while maintaining effective airflow for general case ventilation. PWM control enables automatic speed adjustment based on motherboard fan headers or fan controllers, which helps reduce noise during light loads and increase cooling performance under heavy load. Addressable RGB lighting provides per-fan illumination options when integrated with compatible ARGB headers or controllers. The three-fan pack format simplifies purchasing multiple matched fans for a consistent look.
Suitable for
Case cooling in ATX, Micro-ATX and Mini-ITX desktop systems
Radiator mounting in liquid cooling setups requiring higher static pressure
Builds that use ARGB lighting synchronized via a compatible motherboard or controller
Users who prefer PWM speed control for automated fan speed management
When it may not be suitable
This product is supplied without an ARGB or fan controller, so buyers who do not have a compatible motherboard header or an external controller will need to obtain one separately to use the lighting and advanced control features. If a solely passive or ultra-low-noise solution is required, active fans—even with PWM—may still produce audible noise at higher speeds.
Key specifications
Fan size: 140 mm
Pack quantity: 3 fans
Blade design: reverse-blade for improved static pressure
Speed control: PWM (pulse-width modulation) compatible
Lighting: addressable RGB (requires compatible header or controller)
Color: white (fan frame and blades)
Intended use: case and radiator cooling
How to use
Install the fans in the desired locations within the PC case or on a radiator using standard fan screws. Connect the PWM power cable to a motherboard fan header or PWM-capable controller for speed management. Connect the ARGB lighting cable to a compatible ARGB header or controller to enable addressable lighting control. Configure fan curves and lighting effects through the motherboard or controller software as available, adjusting PWM profiles to balance cooling performance and noise.
What to consider before purchase
Ensure your motherboard or controller supports ARGB addressable lighting and has available headers.
Confirm your case or radiator supports 140 mm fan mounting positions and has clearance for white fans.
Plan for cable routing and connector compatibility for both PWM and ARGB leads.
Usage recommendations
Use these fans on radiators or as case intake/exhaust with PWM control enabled and set conservative fan curves initially; monitor temperatures and adjust speeds to achieve the desired balance between cooling and noise. For ARGB effects, connect to a compatible controller or motherboard software to synchronize lighting across multiple fans.
