Cooling fan lian li UNI FAN TL Wireless 140mm ARGB PWM Black, model 14TL1W1B

The lian li UNI FAN TL Wireless 140mm ARGB PWM Black is a 140mm cooling fan engineered for PC cases and radiators, combining adjustable airflow with addressable RGB lighting and PWM speed control. Its wireless UNI FAN design allows multiple fans to connect and synchronize lighting effects without separate wired lighting hubs, while PWM control provides automatic fan speed regulation according to motherboard or controller signals. The matte black frame and blade design focus on steady airflow and reduced noise for system cooling and radiator use.

Advantages

The fan integrates ARGB lighting with a standardized 140mm form factor and PWM compatibility, enabling synchronized illumination and automatic speed control when connected to compatible motherboard headers or lian li controllers. The UNI wireless connectivity simplifies cable management by reducing lighting cables, and aerodynamic blade geometry aims to balance static pressure and airflow for case ventilation or radiator performance. The black finish offers a neutral appearance that matches most builds.

Suitable for

• Case intake or exhaust for mid-tower and full-tower systems
• Radiator fans for liquid cooling setups
• Multi-fan arrays where synchronized ARGB lighting is desired
• Systems requiring PWM-controlled fan speed for temperature-dependent cooling

Key specifications

• Frame size: 140mm
• ARGB lighting: addressable RGB LEDs for per-fan lighting effects
• Fan control: PWM for automatic speed adjustment
• Mounting: standard 140mm screw pattern for cases and radiators
• Color: black frame and blades

How to use

Install the fan in a 140mm mounting position inside the PC case or on a compatible radiator using the supplied screws. Connect the PWM power cable to a motherboard fan header or PWM fan controller to enable automatic speed control. For ARGB lighting and wireless synchronization, pair the fan with a compatible lian li UNI controller or connect to a supported motherboard ARGB header according to the manufacturers instructions. Ensure airflow direction aligns with your case cooling strategy and that cables are routed to avoid obstructing blades.

Recommendations

Position fans in matched intake and exhaust pairs to create balanced airflow, use PWM control to reduce noise during low loads, and verify compatibility with your motherboard or lian li UNI controller for full ARGB synchronization. Regularly inspect and clean the fan blades to maintain optimal performance.
