Lian Li UNI Fan SL-Infinity 140mm Reverse Blade ARGB PWM Fan Black – G99.14RSLIN1B.00

Uncompromised Aesthetics with Reverse Blade Innovation

Showcase the breathtaking beauty of your custom gaming PC without sacrificing intake cooling efficiency. The Lian Li UNI Fan SL-INF 140 Reverse Blade completely reimagines how you set up intake ventilation. In traditional builds, utilizing standard fans for intake exposes the less attractive rear motor struts, disrupting the visual harmony of modern glass-panel chassis. The reverse blade architecture brilliantly solves this dilemma. It allows the fan to pull cool room air into your system while proudly displaying its pristine front face and mesmerizing infinity mirrors. Engineered specifically for intake efficiency—whether mounted at the bottom of the case or pulling air through a top radiator—this design significantly lowers wind noise compared to standard blades while maintaining a consistent, premium appearance across your entire build.

Endless Depth: The All-Around Infinity Mirror Experience

Immerse your desktop in a corridor of endless light. The SL-Infinity series masterfully combines the iconic angular lighting of the original SL series with the breathtaking depth of an infinity mirror. By densely packing 40 high-luminance Addressable RGB LEDs into the fan, Lian Li ensures brilliant, uniform color saturation. The centerpiece is a circular infinity mirror precisely tuned with multiple reflective layers spaced just 0.5mm apart, creating a striking 3D indented illusion. This aesthetic is further elevated by premium aluminum trims on the frame and dual thin LED strips running along both sides of the fan blades, ensuring that the SL-INF looks dazzling from absolutely any viewing angle.

Unprecedented Modularity and Cable Management

Say goodbye to the nightmare of tangled wires and frustrating cable routing. The UNI Fan SL-INF utilizes Lian Li’s industry-leading 2nd generation interlocking daisy-chain technology. Through an intuitive pin-to-pad contact system, you can seamlessly connect up to four fans together in a single continuous cluster, powering them all through one unified cable connection. To provide unparalleled compatibility with custom water-cooling loops and bulky radiator fittings, Lian Li has engineered the interlocking keylocks to be completely removable. Furthermore, the cable module is intelligently placed at the center of the fan and is fully reversible, effectively eliminating clearance issues with radiator inlets and outlets.

Intelligent Performance and L-Connect 3 Control

Beneath the sophisticated exterior lies a true performance powerhouse. The UNI Fan SL-INF 140 Reverse Blade scales up to an impressive 2100 RPM, delivering 63.6 CFM of airflow and 2.02 mmH2O of static pressure. This smooth and stable operation is driven by an embedded magnetic Fluid Dynamic Bearing (FDB), which drastically reduces mechanical friction to ensure longevity and keep acoustic noise at a highly manageable 32 dB(A). When paired with the Lian Li UNI HUB (sold separately), you gain total mastery over your system via the L-Connect 3 software. Not only can you separately customize the lighting effects of the fan blades and inner frame, but you can also utilize the intelligent Start/Stop fan mode. This feature completely halts the fan when your CPU or GPU drops below a set temperature, guaranteeing absolute silence during light workloads.
