Lian Li UNI FAN SL-INF 140 ARGB Reverse Blade 3x black (no controller)


3-piece bundle of 140 mm PWM fans from Lian Li, unique plug-in system for less cable clutter, with addressable RGB LEDs, infinity mirror effect on the side and front, max. 1,600 rpm, max. 123.5 m³/h airflow, max. 2.88 mmH2O static pressure
The Lian Li UNI FAN SL-INF 140 is aimed at PC enthusiasts who want to combine powerful cooling performance with stylish lighting. Thanks to its innovative plug-in system and ARGB design, this 140 mm fan not only delivers strong performance but also offers a clean setup without unnecessary cables.
- Innovative plug-in system: Connect multiple fans wirelessly into a cluster – for easier cable management
- Powerful cooling: High static pressure and airflow volume for radiators or airflow optimization
- RGB with depth effect: 40 ARGB LEDs with infinity mirrors create impressive effects
- Software control: L-Connect 3 enables precise control of fan speed and lighting
- Quiet & vibration-damped: Up to 1,600 RPM at only 28 dB(A) thanks to rubber decouplers
Easy integration through modular plug-in system
The Lian Li UNI FAN SL-INF 140 uses a clever plug-in system with pin contacts to transmit power, PWM, and ARGB signals. This allows you to operate multiple fans in a single chain – without a separate cable connection for each unit. This not only saves space but also makes installation much easier. This is a real advantage, especially in modern cases focused on cable management.
Optimized compatibility & redesigned layout
The system has been further developed compared to its predecessors: the connector is now detachable to avoid collisions with radiators. The central connection for the 7-pin cable module is compactly positioned in the middle of the frame. This allows you to install the fan more flexibly in tight builds. An included adapter splits the signal for direct connection to the motherboard – perfect for users who don’t want to buy additional accessories.
Efficient cooling for demanding builds
With a hydrodynamic bearing, the SL-INF 140 reaches speeds from 200 to 1,600 RPM while operating quietly. The maximum noise level is only 28 dB(A), making it ideal for silent builds. At the same time, it moves up to 123.5 m³/h of air at 2.88 mmH2O static pressure – a strong combination for use on radiators, air coolers, or as a case fan.
ARGB lighting with a wow factor
The integrated 40 digitally addressable RGB LEDs are precisely distributed: in the rotor hub, along two aluminum strips in the frame, and in multiple infinity mirrors. These create a special visual depth and make the fan a real eye-catcher – whether in white or black builds. Via L-Connect 3, you can customize or synchronize light effects, colors, and speed.
Software & compatibility
Using the included adapter, you can connect the fan directly to your motherboard or pair it with a compatible controller (e.g. LULI-039 or LULI-040). The free L-Connect 3 software lets you control both ARGB lighting and fan speed exactly as you wish. The software automatically detects connected fans and offers comprehensive configuration options.
Compatibility note:
The fans of the SL-INF series are not compatible with SL or AL models. Please ensure you only use controllers from LULI-039 or LULI-040.
