INFINITY MIRROR FAN
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.
CENTERED INFINITY MIRROR ARGB
The circular-shaped infinity mirror at the center of the fan is tuned to have multiple layers spaced 0.5mm apart.
SIDE FRAME ARGB
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.
ALUMINUM TRIM SURROUNDED INFINITY MIRROR
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.

REAR RIM OF LED AROUND THE ALUMINUM LOGO
Inspired by AL fans, there is a bright ARGB rim of light around the LIAN LI logo at the rear.
UNPRECEDENTED MODULARITY
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.

DAISY CHAIN FANA pin-to-pad contact point passes the signal and power through the fan cluster. |

REMOVABLE KEYLOCKThe interlocking key on each fan is now removable to improve compatibility with radiators fittings. |
REVERSIBLE CABLE MODULE
The cable module is now placed at the center of the fan and can switch orientation to reduce clearance issues with the radiator inlet and outlet.

IMPROVED PERFORMANCE
The SL-Infinity 120 features a 10% performance optimization compared to the SL120 which results in better airflow (61.3 CFM), higher static pressure (2.66 mmH2O), and a larger range of fan speed (0, 200 ~ 2100RPM) at lower noise levels (29 dB(A)).

L-CONNECT 3 SOFTWARE TO CONTROL SL-INF FANS
Control and preview with precision the lighting effect of the SL-Infinity fans with the new L-Connect interface.

1 Select lighting effect of blades / fan frame / both LED
2 Set personalized color / brightness / speed / direction
ENDLESS LIGHTING EFFECTS
Similar to the AL fans, L-Connect 3 can set the lighting effects of the SL-Infinity fans for both the fan blades and the fan frame inner edges separately, or go with pre-set combined lighting effects.
Option 1. Set the fan blade and inner fan frame lighting modes individually to achieve a custom look.

INTELLIGENT START/ STOP FAN
Unique to the SL-Infinity fans, L-Connect 3 features a Start/ Stop mode to completely stop the fan when the CPU or GPU is running below your set temperature (the maximum 50°C), achieving minimal acoustic levels when the system is at low temperature.

SYNC FAN SPEED TO MOTHERBOARD
L-Connect 3 now offers an option to sync fan speed to the motherboard, also known as the PWM mode in the earlier L-Connect version.
