Lian Li UNI Fan SL-InFINITY Wireless 120 Triple Pack - ARGB Control

Our review of the Lian Li UNI Fan SL-INFINITY Wireless 120 triple pack finds it best suited for PC builders who prioritize striking lighting and simplified wiring. The single biggest reason to consider these fans is the double infinity mirror ARGB design with three independently controlled light zones that create immersive visuals without the usual cable clutter, since the updated wireless receiver powers both blades and LEDs. Noise and airflow are solid for a high-performance 120mm fan, and the included controller plus L-Connect 3 software make customization straightforward.

Key Features

• Three light zones: Each fan has three independently controlled zones, enabling layered ARGB effects for a standout case presentation.
• Wireless receiver: The redesigned 2.4 GHz receiver powers both the blades and LEDs, reducing cable runs and simplifying installation.
• 12V PWM compatibility: The updated 4-pin cable is compatible with 12V PWM motherboards, letting the fans integrate with standard fan controls.
• Low-noise bearings: Fluid Dynamic Bearings deliver quiet operation up to 2300 RPM while maintaining strong airflow for effective cooling.
• Modular daisy-chain design: Fans can be chained together for cleaner cable management and easier fan placement inside the chassis.
• L-Connect 3 support: Use L-Connect 3 software to tune fan speed, RGB presets, and individual light zones from a single app.

Who It's For

These fans are ideal for gamers, PC enthusiasts, and content creators who want eye-catching ARGB lighting and a cleaner internal layout without running separate LED cables. Builders who value software control will appreciate L-Connect 3 for refining both illumination and fan curves.

Those who need ultra-quiet or low-RPM focused fans might look elsewhere, since these fans aim to balance strong airflow with moderate noise at higher speeds. Also, users without a spare internal USB header or who cannot use the 2.4 GHz receiver may need a different solution.

Pros & Cons

Pros

• Striking double infinity mirror ARGB with three zones produces vivid and customizable lighting.
• Wireless 2.4 GHz receiver reduces cable clutter while powering blades and LEDs together.
• Fluid Dynamic Bearings and modular design offer reliable, relatively quiet performance and tidy cable routing.

Cons

• Noise level can be noticeable at higher RPMs according to some users, so silence-focused builds may prefer slower fans.
