Description
The Lian Li UNI FAN SL-INFINITY (SL-INF) represents the pinnacle of PC aesthetic engineering, merging the iconic daisy-chain modularity of the UNI FAN series with a multi-dimensional infinity mirror design. These fans utilize a slide-in interlocking mechanism to reduce cable clutter, requiring only a single cable for a cluster of up to four fans. With 40 addressable LEDs per unit and a fluid dynamic bearing (FDB), the SL-INF series delivers a balance of silent operation and high-static pressure performance.
This product is for:
- PC Enthusiasts seeking a clean, cable-free interior through modular daisy-chaining.
- Aesthetic-focused builders who want the 3D infinity mirror effect on both the center and side frames.
- High-performance users requiring precise PWM control ranging from 0 to 2100 RPM.
- Custom loop water cooling builders needing high static pressure (2.66 mmH2O) for radiator penetration.
- Showpiece builders who prefer reverse blade fans to maintain intake airflow while keeping the decorative side visible.

Installing the SL-INFINITY fans transforms the building process from a cable management nightmare into a streamlined experience. The interlocking key system allows fans to snap together, significantly reducing the number of headers required on the motherboard or controller. In operation, the L-Connect 3 software provides granular control over lighting effects and fan curves. The infinity mirrors on the sides and center create a depth effect that remains visible from multiple angles, making them ideal for tempered glass cases.
Compared to the original SL120, the SL-INFINITY increases the LED count and adds the signature mirror effect on the hub and frame. While the regular SL-INF is optimized for exhaust or radiator pushing, the Reverse Blade variant is specifically engineered for intake positions at the bottom or side of a chassis. This ensures that the infinity mirror hub faces the user even when pulling air into the case, a distinct advantage over traditional fans where the rear motor cage often blocks the view.
Q&A:
- What is the difference between regular and reverse blade fans? Regular fans blow air toward the motor cage (exhaust), while reverse blades pull air through the motor cage (intake), allowing the decorative side to face forward during intake.
- How many fans can be connected to a single cable? Up to four UNI FAN SL-INFINITY units can be daisy-chained together and powered by one cable set.
- Does this fan support 0 RPM mode? Yes, the fans can be configured to stop completely when temperatures are below a certain threshold for silent operation.
- Is a controller included with single-pack fans? No, the single-pack (1-pack) does not include a controller; it is intended as an expansion for the 3-pack or for direct motherboard connection.
- What software is used to control the lighting? Lian Li’s L-Connect 3 software is the primary tool for managing fan speeds and ARGB lighting effects.
