Lian Li UNI Fan SL-Infinity 120 Triple Pack - Infinity Mirror ARGB

Our review of the Lian Li UNI Fan SL-Infinity 120 triple pack finds it best suited for PC builders who prioritize show-stopping lighting and clean cable management without sacrificing quiet operation. The single biggest reason to buy is the multi-layer infinity mirror effect driven by 40 LEDs per fan, which creates a deep, reflective RGB look visible from almost any angle while still offering solid airflow and a start/stop mode for silent idle operation.

Key Features

• Infinity mirror design: The layered reflective surface highlights the 40 LEDs in each fan to produce a pronounced depth effect from multiple viewing angles.
• Daisy-chain interlocking: The interlocking style keeps cables tidy and allows fans to snap together for easier installation and reduced clutter.
• Included controller: The pack includes a controller that supports up to 16 fans and two SM-type devices, making it simple to expand lighting across a build.
• Removable cable module: The reversible cable module and keylock design improve compatibility with tight radiator fittings and allow flexible cable routing.
• Magnetic fluid dynamic bearing: The embedded FDB provides stable operation, durability, and long life while maintaining quiet acoustics.

Who It's For

These fans are ideal for enthusiasts building a showcase PC or a white-themed system who want vivid, customizable ARGB effects and neat cable management without complex wiring. The included controller and daisy-chain design make them attractive to builders who may add more fans later and want consistent lighting across multiple units.

Those who should look elsewhere are users who need extreme static pressure for very dense radiators beyond typical case cooling or who require absolute silence under heavy sustained loads; while these fans reach up to 2100 RPM and offer a stop mode at low temperatures, they are designed as balanced case and AIO fans rather than specialized high-pressure blower fans.

Pros & Cons

Pros

• Striking infinity mirror lighting with strong color customization and 40 LEDs per fan.
• Excellent cable management thanks to the interlocking design and single-cable daisy chaining.
• Quiet and reliable operation with magnetic fluid dynamic bearings and a usable start/stop mode.

Cons

• The fans can reach higher RPMs for increased airflow which may be noticeable under load compared with very low-noise specialty fans.

Frequently Asked Questions

Can these fans be linked together?
Yes, the interlocking daisy-chain design and included controller let you snap and link multiple fans with a single cable path for both power and lighting.

Will they fit radiator mounts?
The removable keylock and reversible cable module improve clearance and compatibility with radiators, but builders should check their radiator spacing for cable routing.

Are they noisy at full speed?
At top speeds up to 2100 RPM they are more audible than idle, but customers report generally quiet operation under normal loads thanks to the FDB design.
