This article covers LIANLI ケースファン 「UNI FAN」シリーズ UNI FAN SL-INFINITY 140 REVERSE BLADE ブラック ブレード反転モデル デイジーチェーン リバーシブルケーブルモジュール インフィニティーミラー搭載 UF-RS-SLIN140-1B 日本正規代理店品 (× 3).

Overview

Lian Li's UNI FAN SL-INFINITY 140 REVERSE BLADE is a 140mm case fan with a reverse blade design, offered in a 3-pack. Unlike traditional fans that show the frame side on intake, this fan's reverse rotation allows the visually striking infinity mirror and LED-lit hub to face inward, perfect for showcasing in a tempered glass case. The fan features Lian Li's patented daisy-chain connection, simplifying cable management. It supports both motherboard ARGB control and L-Connect 3 software via the optional UNI HUB. This product targets PC builders who value aesthetics, clean wiring, and integrated lighting control without sacrificing airflow.

Compatibility Guide

The fan uses standard 140mm mounting holes (125mm pitch) and fits most mid-tower and full-tower cases that support 140mm fans. It is not compatible with 120mm mounts. The default thickness is 25mm, so clearance for CPU cooler and GPU is generally not an issue, but check that your case has enough depth for a 140mm fan at the desired position. The daisy-chain allows connecting up to 4 fans via a single PWM and ARGB cable, greatly reducing clutter. Power is provided via standard 4-pin PWM and 3-pin ARGB headers. If you wish to use L-Connect 3 for unified control, you will need the separately sold UNI HUB (controller).

Product Info

Released in early 2024, the UNI FAN SL-INFINITY 140 REVERSE BLADE 3-pack retails around ¥11,700 on . It sits in the premium segment of case fans, justified by its unique infinity mirror lighting and convenient daisy-chain design. The fan uses a fluid dynamic bearing (FDB) for longevity and quiet operation. While exact RPM, airflow, and noise levels are not officially listed, based on the standard SL-INF 140mm, it likely operates up to 1500 RPM with decent static pressure suitable for radiator use.

Best Use Cases

Aesthetic-focused PC builds: The reverse blade ensures the "good side" faces the interior, ideal for intake configuration. The infinity mirror effect is mesmerizing, especially in dark environments. Cable management enthusiasts: The daisy-chain drastically reduces fan cables. For a build with 6 fans, you only need 2 daisy-chain cables for the 3 fan groups (if using two packs). * Gamers wanting synchronized RGB: If you already own other UNI FAN SL-INFINITY fans (120mm), you can mix sizes as long as they are on separate channels or hubs. The L-Connect 3 software offers intuitive control. Not ideal for: Budget builds or noise-sensitive silence seekers who prefer cheaper non-LED fans. ## Alternatives
Direct competitors include Corsair iCUE QL140 RGB and NZXT F140 RGB Duo. Corsair's ecosystem is robust but requires its own controller and more cables. The Lian Li fan wins on cable simplicity and the unique infinity mirror aesthetic. If you prefer software integration with motherboard RGB sync, the Lian Li offers flexible control without a proprietary hub (for simple ARGB). For pure performance and lower cost, consider Arctic P14 PWM PST.

Things to Consider

The UNI HUB is not included in the 3-pack; budget an additional ¥2,000 if you want L-Connect 3. The reverse blade is designed for intake; do not use it as an exhaust fan where the frame would face outward. Also, these fans are 140mm only — verify your case supports 140mm at the intended mounting points. If you plan to use them on a radiator, the static pressure may be lower than dedicated radiator fans; the SL-INF 120mm is a better choice for AIO. ## FAQ Q: Does the fan come with the UNI HUB? A: No, the 3-pack does not include the hub. The hub must be purchased separately for L-Connect 3 control. Q: Can I use this fan without ARGB? A: Yes, you can simply not connect the ARGB cable. The fan will still spin and be controlled via PWM. Q: Is the daisy-chain compatible with other UNI FAN series? A: Yes, the daisy-chain connectors are the same across UNI FAN SL-INF and AL120/140 series, but mixing different generations may lead to different lighting or behavior. Lian Li recommends using fans of the same series on the same chain.
