Lian Li UNI FAN SL-INF Wireless ARGB PWM Reverse Blade 140mm -tuuletin, valkoinen

Lian Li UNI FAN SL-INF Wireless ARGB PWM Reverse Blade 140mm fan, white is a 140mm cooling fan designed for PC cases, radiators and general system ventilation. The fan combines a reverse blade geometry with PWM speed control and addressable RGB lighting to balance airflow performance and acoustic comfort. Wireless control enables simplified connection between multiple fans for synchronized speed and lighting management, and the white finish suits light-coloured builds.

Advantages

The reverse blade design improves airflow efficiency while reducing turbulence compared with conventional blade shapes. PWM control provides automatic speed adjustment based on system temperature, helping to maintain target thermal levels with lower noise at idle. Addressable RGB lighting allows customizable illumination effects that can be synchronized with other ARGB components. The wireless connection reduces cable clutter and simplifies installation when linking several fans in a single loop.

Suitable for

• Case ventilation in mid-tower and full-tower PCs
• Push or pull configurations on 140mm-compatible radiators
• Quiet system fan for white or light-colour builds
• ARGB lighting setups requiring synchronized effects

Key specifications

• Fan size: 140 mm
• Blade design: reverse blade for optimized airflow
• Speed control: PWM (pulse-width modulation) compatible
• Lighting: addressable RGB (ARGB) per-fan lighting support
• Colour: white frame and blades
• Connection: wireless link for integrated fan speed and lighting control
• Mounting: fits standard 140mm fan mounts

How to use

Install the fan into any standard 140mm mount using the included screws, orienting the airflow according to your case or radiator configuration. Connect the fan to the system’s PWM header or to the manufacturer’s wireless controller as instructed to enable automatic speed regulation. Use the ARGB control interface compatible with the wireless link to set lighting effects and synchronization with other ARGB devices. Ensure clear airflow paths and avoid obstructing the blades during operation.

Recommendations

For balanced cooling and low noise, use PWM control linked to motherboard temperature sensors and position the fan to complement case airflow (intake/front or exhaust/rear). When mounting on radiators, verify push or pull orientation for your cooling setup and maintain regular cleaning to preserve airflow and lighting appearance.
