Lian Li SL-Infinity 120-3 UNI Cooler Case Fan is a combination of the original UNI FAN SL and AL with a touch of infinity mirror, the SL-Infinity fans glow clear with multi-layer effects from any visible angle. The circular-shaped infinity mirror at the center of the fan is tuned to have multiple layers spaced 0.5mm apart. Following the iconic angular lighting style of SL fans, the SL-Infinity fans have 2 thin LED strips on both sides of the fan blade. Surrounding aluminum trims are located on both sides of the frame. The geometric shape of the infinity mirror follows the front ARGB lighting strip in a top and bottom pattern that creates a 3D indented look. Inspired by AL fans, there is a bright ARGB rim of light around the LIAN LI logo at the rear. The 2nd generation of UNI FAN SL revisits the interlocking style that can connect up to 4 fans in a cluster and makes cable management simpler and improves compatibility with radiators fittings.
