## Summary description

Pack of Lian Li UNI FAN SL-INF 140 ARGB reverse-blade PWM case fans (model GABU-732) comprising three 140mm white fans plus one additional 140mm fan. Each fan features PWM speed control for adjustable airflow, reverse blade geometry for airflow optimization and ARGB lighting for customizable illumination. Suited for PC cooling, radiators and case ventilation in desktop builds.

## Long description

The Lian Li UNI FAN SL-INF 140 ARGB Reverse Blade PWM fan pack is a set of four 140mm case fans in white designed for desktop PC cooling. The bundle includes three fans configured as a linked pack plus one additional identical 140mm fan, all featuring reverse blade geometry to optimize airflow and reduce turbulence. Each fan supports PWM speed control for precise RPM management and includes integrated ARGB lighting for customizable illumination when connected to compatible headers or controllers.
Advantages
These 140mm fans combine reverse-curved blades and PWM control to deliver stable airflow with reduced noise at typical operating speeds. The integrated ARGB lighting is built to work with standard 3-pin addressable RGB ecosystems, providing synchronized lighting effects when connected to compatible motherboards or controllers. The modular design used by this fan series simplifies installation and cable management in cases with limited space.
Suitable for
 Case ventilation in mid-tower and full-tower desktop builds
 Mounting on 140mm-compatible radiators for liquid cooling loops
 Replacing existing 140mm intake or exhaust fans to improve airflow
 Systems where ARGB lighting synchronization is desired
When it may not be suitable
This fan pack is sized for 140mm mounting locations and may not fit cases or radiators that only support 120mm fans. If a build requires ultra-low-noise passive cooling at very low RPMs, alternative low-speed or larger-diameter fans could be more appropriate. The lighting features require an addressable RGB header or compatible controller to access full ARGB functionality.
Key specifications
 Fan size: 140 mm
 Quantity: 4 fans (3-pack linked + 1 additional fan)
 Blade design: reverse blade geometry for airflow optimization
 Speed control: PWM (pulse width modulation) for variable RPM
 Lighting: addressable RGB (ARGB) lighting
 Color: white frame and blades
 Mounting: standard 140mm screw pattern
How to use
Install the fans into 140mm-compatible mounting positions in your case or on a compatible radiator using the supplied screws. Connect each fan to the system using the PWM power connector for speed control and the ARGB connector to a compatible 3-pin addressable RGB header or controller for lighting. Configure fan curves and ARGB effects in motherboard software or via a separate controller to balance cooling performance and noise. Ensure airflow orientation matches your intended intake or exhaust layout.
What to consider before purchase
 Confirm your case or radiator supports 140mm fan mounting locations
 Verify your motherboard or controller has a 3-pin addressable RGB header for ARGB control
 Check available PWM fan headers or fan hub compatibility for controlling multiple fans
 Assess whether white fan color matches your build’s aesthetic
Usage recommendations
For typical desktop cooling, configure two fans as intake at the front and one or two as exhaust at the rear/top to establish positive or neutral case pressure. Use PWM fan curves to limit maximum RPM under light loads and increase speed when temperatures rise. When mounting to radiators, ensure there is sufficient clearance for the fan thickness and confirm push or pull orientation based on your liquid cooling setup.
