This article covers LIANLI 連結型ケースファン UNI FAN SL140 V2 WT Single Pack ホワイト 流体軸受 「L-CONNECT 3」対応 日本正規代理店品.

Overview

Lian Li's UNI FAN SL140 V2 WT is a 140mm case fan designed for clean, daisy-chained builds. Up to six fans can be linked through a single cable module, drastically reducing cable clutter. The fluid dynamic bearing ensures quiet operation and long-term reliability. With the dedicated L-CONNECT 3 software, you can control RGB lighting and fan speeds in one interface. This single-pack white variant suits users who want a uniform color scheme and a sleek interior. In the market, it sits at the mid-range tier, balancing aesthetics, quietness, and ease of installation.

Compatibility Guide

This fan fits any case with a 140mm mounting point. To use the daisy-chain feature fully, you need a controller (included with the 3-pack) or an L-CONNECT 3 compatible controller. It uses a 3-pin connector, so speed control is via voltage (DC) on the motherboard; PWM control is not supported. An 18cm extension cable allows bridging two clusters of up to 3+3 fans. Ensure your motherboard has an ARGB header for independent lighting control when using a single pack without a controller.

Product Info

The UNI FAN SL140 V2 launched in late 2022 and is widely available through retailers like . Warranty typically covers 2 years. The fluid dynamic bearing provides a rated noise level of 29 dBA and airflow of 77.6 CFM, making it a quiet but capable performer. As a mid-range product, it emphasizes cable management and customizable RGB lighting, appealing to builders who prioritize aesthetics without sacrificing core cooling.

Best Use Cases

Cable-management focused builds: The daisy-chain system drastically reduces wiring, ideal for compact cases or showcase PCs where neatness matters. Quiet computing setups: Fluid dynamic bearing combined with low vibration makes this fan near-silent at low speeds, suitable for HTPCs or recording studios. * RGB lighting enthusiasts: L-CONNECT 3 offers per-fan LED control, allowing complex lighting effects that can be synced with other Lian Li products for a cohesive look. ## Alternatives
Corsair LL140 RGB ($35) offers more dramatic RGB rings but lacks daisy-chaining, leading to more cables. Noctua NF-A14 PWM ($25) delivers superior airflow and silence but has no RGB. The UNI FAN SL140 V2 sits between them, providing good quiet performance with excellent cable management and addressable RGB, making it the best all-rounder for aesthetic-driven builds.

Things to Consider

The 3-pin connector means precise PWM speed control is not possible; you must rely on motherboard DC control. If you need strict fan curves, consider a PWM model. The single pack does not include a controller, so daisy-chaining more than two fans may require purchasing the 3-pack or a separate controller kit. Airflow at 77.6 CFM is modest compared to some high-performance fans (e.g., Noctua NF-A14 at 140 CFM), so it may not be ideal for extreme overclocking or high-heat systems. But for general use and quiet operation, it’s a solid choice.
