Lian Li UNI FAN SL FLEX Wireless ARGB Reverse Blade 120mm PWM Case Fan - Black

Most case fans push air from the front, hiding their best side. The Lian Li UNI FAN SL FLEX Wireless ARGB Reverse Blade flips the script: its reverse-oriented blades pull air through the fan while keeping the visually striking rotor facing the interior of your build. That means a clean, unobstructed view of the interlocking fan frame and vibrant ARGB lighting without sacrificing airflow performance. Combined with Lian Li's signature daisy-chain interlocking system and wireless control via the L-Connect 3 ecosystem, this fan is built for builders who demand both aesthetics and cable-free simplicity.

Highlights

• Reverse blade design: ideal for bottom or side intake positions where you want the fan's lit side visible inside the case.
• Wireless ARGB lighting and PWM speed control via the Lian Li UNI FAN wireless controller (sold separately) and L-Connect 3 software.
• Fluid Dynamic Bearing (FDB) for quiet operation, long lifespan, and stable performance at any orientation.
• Interlocking UNI FAN design: connect multiple fans together with a single cable for power and lighting, reducing clutter.
• Premium construction with PBT, PC, and aluminum frame components for rigidity and a premium feel.

In daily use

This 120mm fan delivers up to 61.3 CFM of airflow and 2.83 mmH2O of static pressure, making it suitable for both unrestricted airflow and radiator or mesh-filter intake scenarios. The PWM control allows the fan to spin anywhere from 0 to 1800 RPM, so it can stay silent at idle and ramp up under load. The reverse blade orientation ensures that the illuminated side faces your tempered glass panel, showcasing the interlocking frame and ARGB effects without any visible support struts blocking the view.
