Lian Li UNI FAN SL V2 SL140 - Flush Cable Case Fan

In this review of the Lian Li UNI FAN SL V2 SL140, the bottom line is simple: build-focused PC enthusiasts who need tidy cable routing and minimal clearance fuss will appreciate this fan. The standout is the cable module that plugs in and sits flush with the fan frame, which reduces interference with radiator accessories and keeps tight builds neater. The reviewer found the design thoughtful for compact radiators and dense front-panel setups, delivering the practical benefit of cleaner installation without requiring extra space behind the fan frame.

Key Features

• Flush cable module: The cable module plugs in and sits flush with the fan frame so it does not add depth or complicate clearance with radiator fittings.
• Space-saving layout: The reduced projection from the fan means easier stacking against radiators and less chance of hitting tubing or screw heads when mounting.
• Installation-friendly: The design simplifies cable routing behind the fan frame, making cleaner builds faster to assemble.
• Case compatibility: The fan is aimed at modern cases and cooling arrays where limited behind-frame space is common, helping avoid fitment surprises.
• Brand engineering: The unit continues Lian Li's focus on practical hardware touches that prioritize usable space inside the chassis.

Who It's For

The Lian Li UNI FAN SL V2 SL140 is best for PC builders who run radiators in tight front or top mounts and need every millimeter of clearance. Enthusiasts who value clean cable routing and a compact footprint around fan frames will find this fan a practical upgrade over standard designs that rely on bulky cable modules.

It is less relevant for users who do not face clearance constraints or who prefer fans optimized primarily for maximum airflow or RGB showmanship over compact cable integration. If you only mount fans where space is abundant, a simpler, lower-cost fan could be a better choice.

Pros & Cons

Pros

• Flush cable module minimizes added depth and eases installation next to radiators.
• Cleaner cable routing behind the fan frame simplifies tidy builds and cable management.
• Designed to reduce clearance issues with radiator accessories in tight mounts.

Cons

• Not primarily positioned as a high-performance airflow or acoustics flagship, so those priorities may warrant other choices.
