This article covers Lian Li UNI FAN SL-INFINITY リバーシブル 120W.

Overview

The Lian Li UNI FAN SL-INFINITY Reverse Blade 120W is a specialized variant of the popular SL-INFINITY series, featuring reversed blade rotation to deliver intake airflow while keeping the infinity mirror illumination visible from the interior of the case. Standard fans hide the mirror effect on the intake side, but this reverse model solves that problem, making it ideal for front or bottom intake positions where aesthetics matter. Key specifications include a standard 120mm x 25mm form factor, maximum airflow of 61.3 CFM, and noise levels up to 32 dBA. It uses a 4-pin PWM connector for speed control and a 3-pin 5V ARGB header for lighting. The fan can be daisy-chained with other UNI FAN SL-INFINITY units using the modular interlocking mechanism, drastically reducing cable clutter. Positioned as a premium case fan, it targets enthusiasts building high-end gaming PCs or workstations where both cooling performance and visual appeal are priorities. The ability to control up to four fans via a single cable through the UNI HUB and L-Connect 3 software sets it apart from conventional RGB fans.

Compatibility Guide

This fan fits any standard 120mm mounting hole pattern, compatible with the vast majority of PC cases. However, because it is a reverse-blade model, it is intended for intake use only (front or bottom). For exhaust, you should use the standard SL-INFINITY fan. Power is supplied via a 4-pin PWM header, and ARGB control uses a 3-pin 5V addressable RGB header. For daisy-chaining, the UNI HUB (sold separately or included in multi-packs) is required to connect up to four fans with a single cable and manage them via L-Connect 3. Without the hub, each fan must be connected individually to the motherboard. When planning your build, ensure your case has enough clearance for the interlocking mechanism, especially in tight spaces. Also verify that your motherboard has sufficient 4-pin fan headers and 5V ARGB headers if you choose not to use the hub.

Product Info

Released in late 2023, the Lian Li UNI FAN SL-INFINITY Reverse Blade 120W is priced around ¥3,300 per unit ( Japan reference). It is available as a single pack or in multi-packs that include the UNI HUB. The warranty is 2 years for official Japanese distributor products. This fan sits in the high-end segment of the case fan market. Its unique reverse-blade design, infinity mirror lighting, and daisy-chain capability justify the premium price for users who value both performance and aesthetics.

Best Use Cases

Aesthetic-focused gaming builds: Perfect for users who want to showcase infinity mirror lighting on intake fans. Combine with standard SL-INFINITY fans for exhaust to create a cohesive, stunning look. Cable management enthusiasts: The daisy-chain system reduces the number of cables from multiple fans to just one, making for a cleaner interior and better airflow. * L-Connect 3 ecosystem users: If you already use Lian Li products like AIO coolers or Strimer cables, this fan integrates seamlessly into the same software control environment.

Things to Consider

This fan is strictly for intake use; do not use it for exhaust. You will need to purchase standard SL-INFINITY fans separately for exhaust positions. Additionally, to fully benefit from the daisy-chain feature, the UNI HUB is required—without it, you lose the cable reduction advantage. The price per fan is higher than entry-level RGB fans. If budget is a primary concern, consider more affordable alternatives. Also, if you plan to use multiple fans without the hub, ensure your motherboard has enough 5V ARGB headers to avoid the need for splitters.
