This article covers Lian Li ケースファン UNI FAN SL INFINITY 140 ブラック Single Pack デイジーチェーン接続 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 日本正規代理店品.

Overview

The Lian Li UNI FAN SL INFINITY 140 is a 140mm PWM case fan that combines strong airflow, quiet operation, and stunning RGB lighting. With a maximum speed of 1600 RPM, it moves 72.7 CFM of air while keeping noise at just 28 dBA. The standout feature is its daisy-chain design: you can connect up to four fans without individual cables, drastically reducing cable clutter. The infinity mirror effect on the center hub and side edge adds a multi-layered lighting look that’s fully customizable via L-Connect 3 software. This 140mm variant joins the SL-INFINITY family, offering larger airflow than the 120mm version—ideal for front or top intake in mid-to-full tower cases. It’s available in black and white; this review covers the black single pack.

Compatibility Guide

Case support: Standard 140mm fan mounting holes; ensure your case has 140mm positions (most ATX/mATX cases do). Connector: 4-pin PWM for fan speed, plus a proprietary daisy-chain cable for power and ARGB. The single pack does not include a controller; you can connect directly to a motherboard ARGB header (5V 3-pin) or purchase the UNI FAN controller separately. * Software: L-Connect 3 (recommended for full control) or motherboard RGB utilities.

Product Info

Released in late 2022, the single pack sells for around ¥3,900 (as of June 2026). Warranty is 2 years. The fan occupies a mid-to-high-end position in Lian Li’s lineup, targeting builders who value clean aesthetics and simplified wiring. Power draw is a low 5.16W, so even four daisy-chained fans won’t stress your PSU.

Best Use Cases

Cable-management obsessives: The daisy-chain system turns a tangle of fan wires into a single neat run – a game-changer for showcase builds. RGB enthusiasts: The infinity mirror creates a deep, endless-light effect that stands out even in tempered-glass cases. Each fan’s hub and rim LEDs can be controlled independently. * Quiet PC builders: At max speed the fan is hardly audible (28 dBA), and at lower RPM it’s near-silent. Perfect for HTPCs or quiet workstations. ## Alternatives
Noctua NF-A14 PWM – superior raw cooling and silence, but no RGB and separate cables. Corsair ML140 – higher static pressure, great for radiators, but requires Corsair iCUE ecosystem for lighting sync. * If you want lighting without messy wiring, the UNI FAN SL INFINITY 140 is the best balance.

Things to Consider

Single pack contains no controller. To use daisy-chain with L-Connect 3, buy the 3-pack or a separate UNI FAN controller. If connecting directly to a motherboard ARGB header, you lose some software features (e.g., per-fan effects). Confirm your case supports 140mm fans – many compact/mATX cases only accept 120mm. Maximum daisy-chain is 4 fans; ensure your fan header can supply enough current (each fan draws ~0.43A at full speed).
