Ventilador de caja Lian Li UNI FAN SL-INF Wireless ARGB PWM de 140 mm, negro

The Lian Li UNI FAN SL-INF Wireless ARGB PWM 140mm case fan, black, is a 140mm cooling solution for desktop PCs that combines wireless ARGB lighting control with PWM-based speed regulation. Engineered for compatibility with standard 140mm mounts, the fan integrates into gaming rigs, workstations and quiet home systems where adjustable airflow and synchronized lighting are required. The design focuses on simple installation and a compact footprint while offering addressable RGB illumination and fan speed control for temperature management.

Advantages

This fan provides wireless ARGB control for flexible lighting without extensive cabling and supports PWM for accurate fan speed adjustments to balance cooling performance and noise levels. The 140mm form factor delivers a larger airflow volume compared with smaller fans at equal rotational speeds, and the black finish is suitable for a wide range of case interiors. The product is designed to work with standard mounting points and to integrate with multi-fan setups for consistent lighting and airflow behavior.

Suitable for

• Custom gaming PCs requiring adjustable lighting and airflow
• Workstations that need quiet cooling with PWM control
• Home systems where cable reduction and synchronized ARGB are preferred

Key specifications

• Fan size: 140 mm
• Lighting: Addressable RGB (ARGB) with wireless control
• Speed control: PWM (pulse width modulation) for variable fan speed
• Color: Black frame and blades
• Mounting: Standard 140 mm case mounts

How to use

Install the fan in any standard 140 mm mounting position inside the PC case using the provided screws or mounting hardware. Connect the fan to the system power and PWM header or to the provided wireless hub as instructed by the manufacturer to enable speed control and wireless ARGB management. Configure fan curves in the motherboard BIOS or fan control software for optimal thermal performance, and use the wireless ARGB controls to set desired lighting effects and synchronization across compatible fans.

Recommendations

Place the fan where it supports the desired airflow path—intake at front/bottom or exhaust at top/rear—so that case airflow is balanced. Use PWM-based profiles to reduce noise during light workloads and increase speed under heavy loads. When using multiple fans, synchronize ARGB settings via the wireless control method to maintain consistent lighting effects.
