Maximum Airflow
This fan pushes 67 CFM of airflow through its blades, making it a powerful choice for maintaining low temperatures in push/pull configurations. Its PWM functionality allows for dynamic fan speed control, adjusting to your system’s needs for good cooling without waste or noise.

Daisy Chain Design
The interlocking design enables up to four fans to be daisy-chained together with ease, eliminating clutter and simplifying installation. This feature transforms UNI Fans into a game-changer, providing effortless control and unified performance in modern PC builds.

Fans to Motherboard: 
Each fan or daisy-chained group requires a 4-pin PWM cable for power and speed control. A 3-way SATA PWM splitter is included in triple packs so you can expand outwards, either to matching SL-INF sets or maybe other UNI FAN types if you like!

2.4GHz USB 2.0: 
Here’s where the wireless part comes in. The L-Wireless controller manages all lighting and fan control over 2.4GHz, letting your system run clean and cable-free from the outside. Simply plug it into your motherboard’s rear USB Type-A port—or alternatively, use an internal 9-pin USB header if preferred.

Bridging The Ecosystem
The controller supports multiple fan groups, with each group occupying its own channel for stable control. It’s also fully compatible with the Strimer Wireless Series, allowing you to use additional channels for other devices, ensuring a seamless and scalable setup for your PC.

Dual Infinity Design
The UNI FAN SL-INF features three distinct lighting zones per fan: the fan blades, the outer frame, and the signature infinity mirrors on each side - featuring a different pattern depending on which way the fan is facing. Together, they create a layered platform for advanced lighting effects across your build. Every zone is fully customisable through L-Connect 3, allowing for dynamic gradients, alternating color schemes, or clean, uniform visuals

Precision PBT Blades
The thick polybutylene terephthalate (PBT) blades are engineered for rigidity and minimal flex. This design clears lots of room for static pressure while preventing turbulence.

Reinforced Core Stability
Moving inward, a high-strength metal bearing secures the impeller in place. A surrounding rubber ring helps absorb vibrations, keeping noise levels low and holding balance.

Engineered Fan Frame
A reinforced 28mm-thick fan frame completes the structure, built for durability and airflow efficiency. Rubber dampening pads at each corner absorb residual vibrations, staying quiet at all times.

Fluid Dynamic Bearing
At the heart of the fan lies the fluid dynamic bearing (FDB), designed to keep friction to a minimum and max out on lifespan. Supported by a brass nut, stator, and shaft, this system allows for smooth and stable rotation.

Full Customisation in One Place
L-Connect 3 delivers a clean, intuitive interface designed for full control of your UNI FAN setup. The dashboard is split into straightforward sections—fan speed, lighting, grouping—so you can jump into exactly what you need without any digging. Fans are displayed in chains and can be renamed, sorted, and grouped visually, making large or mixed setups easy to manage at a glance.
