Cooling fan Lian Li UNI FAN TL LCD Wireless 140mm ARGB PWM Reverse Blade

The Lian Li UNI FAN TL LCD Wireless 140mm ARGB PWM Reverse Blade is a case cooling fan designed for PC builders who need adjustable airflow, customizable lighting and quiet operation. This 140mm fan uses a reverse blade geometry to improve static pressure and airflow distribution inside the chassis. Integrated wireless control and an LCD module enable on-fan visual customization without requiring additional control wiring, while PWM speed control allows the system to regulate fan rpm according to temperature or motherboard settings.

Advantages

The reverse blade design enhances airflow efficiency and static pressure compared with conventional blade shapes, promoting better cooling of radiators and case interiors. ARGB lighting supports multiple color effects and sync options, while the built-in LCD provides an additional display surface for system visuals or information. Wireless control simplifies installation and reduces cable clutter, and PWM compatibility ensures precise speed regulation and quieter operation at low loads.

Suitable for

• PC cases requiring 140mm intake or exhaust fans
• Cooling radiators where improved static pressure is beneficial
• Custom builds seeking ARGB lighting and an integrated LCD element
• Systems that use PWM fan headers for automatic speed control

Key specifications

• Fan size: 140 mm
• Blade type: reverse blade geometry for enhanced static pressure
• Lighting: addressable RGB (ARGB) support
• Control: wireless control functionality and on-fan LCD module
• Speed control interface: PWM for motherboard or controller-based rpm regulation
• Mounting: standard 140 mm fan mounting footprint
• Intended use: case airflow and radiator cooling

How to use

Install the fan into a compatible 140mm mounting location in your PC case using the supplied screws or standard fan screws. Connect the power and PWM control cable to an available PWM-capable fan header on the motherboard or to a PWM controller to allow automatic speed regulation. Use the provided wireless interface to pair the fan with its controller or hub and configure ARGB effects and the LCD display content through the vendor app or compatible control hardware. Position the fan to match your intended airflow direction—intake or exhaust—and verify clearances to adjacent components.

Recommendations

For quiet operation, allow the motherboard or PWM controller to manage fan speeds and avoid running at maximum rpm continuously. When mounting on radiators, ensure an even push/pull configuration if using multiple fans to optimize static pressure and cooling performance. Keep the wireless receiver in a clear line of sight from the fan’s wireless transmitter for stable control and check firmware or app updates for expanded LCD and ARGB features.
