Lian Li UNI FAN SL-INF 120 FLEX Wireless ARGB Case Fan - Black

PC builders chasing both performance and aesthetics will find the Lian Li UNI FAN SL-INF 120 FLEX Wireless a perfect match for high-airflow builds. This 120 mm black fan delivers up to 72.7 CFM airflow and 2.86 mmH2O static pressure, while its reversible blade design lets you flip between intake and exhaust without changing the frame orientation. The infinity mirror effect on both sides, powered by 40 addressable RGB LEDs, creates a stunning visual centerpiece in any tempered-glass chassis.

Key specifications

• Fan size: 120 mm (28 mm thick)
• Speed: 0–2100 RPM (PWM controlled)
• Airflow: up to 72.7 CFM
• Static pressure: up to 2.86 mmH2O
• Noise: max 29.2 dBA
• Bearing: Fluid Dynamic Bearing (FDB)
• Connector: 4-pin PWM (requires Lian Li controller for full functionality)
• Lighting: Addressable RGB (ARGB), 40 LEDs (20 per side), DC 5V
• Fan rated voltage: DC 12V
• Material: PBT / PC / Aluminum
• Daisy-chain interlocking system for clean cable management

Why choose it

The reversible blade design solves a common build dilemma: you can maintain the same visual orientation while switching airflow direction, keeping your RGB effects uninterrupted. The daisy-chain interlocking system reduces cable clutter, and the FDB bearing ensures quiet, long-lasting operation. With L-Connect 3 software, you can synchronize lighting effects across multiple fans and other Lian Li devices.

Ideal use cases

• High-airflow gaming PCs with tempered glass panels
• Custom water-cooling loops needing strong static pressure
• Showcase builds where the infinity mirror effect is a highlight
• Quiet workstations that still demand efficient cooling

Good to know

The fan requires a Lian Li controller (sold separately) for full PWM and ARGB functionality. The package includes the fan only; mounting screws are not listed, so check your case or radiator hardware. The 28 mm thickness is slightly more than standard 25 mm fans, so verify clearance in tight spaces.
