The Lian Li UNI Fan SL140 V2 (UF-SL140V2-1W) takes the legendary aesthetic of the original UNI Fan series and refines it for even better thermal performance and easier installation. Designed for extreme PC builders who want a pristine, wire-free aesthetic, this 140mm white cooling fan utilizes a patented interlocking system to snap together with other SL V2 fans. The result is a seamless, continuous block of ARGB lighting and heavy-duty cooling power without the nightmare of managing dozens of individual fan wires behind your motherboard.
• Key Features
Revolutionary Daisy-Chain Design: Slide-in PIN-to-PIN interlocking mechanism allows you to physically link up to 6 fans in two clusters to a single controller port, drastically simplifying cable management.
Upgraded 28mm Frame: The slight increase to a 28mm thickness (compared to the standard 25mm) provides a 10% increase in airflow and static pressure, creating a perfect balance for both case intake and thick liquid cooling radiators.
Removable Interlocking Keys: The physical locking tabs on the sides of the fan can now be removed, ensuring perfectly flush compatibility with tight radiator fittings or small form factor cases.
Flush Plug-in Cable Module: The power/signal cable module now sits completely flush with the fan frame, avoiding clearance issues and keeping the overall footprint incredibly sleek.
Sophisticated ARGB Edge Lighting: Features 32 addressable RGB LEDs that shine through premium diffusers on the top and bottom edges, ensuring smooth, vibrant lighting effects visible from multiple angles.
L-Connect 3 Control: When paired with a Lian Li UNI HUB (sold separately), unlock total customization over fan curves and intricate lighting sync effects through the intuitive L-Connect 3 software.
• Performance / Technology
Equipped with a high-quality Fluid Dynamic Bearing (FDB), the SL140 V2 is engineered for extreme longevity and silence. The fan operates dynamically between 250 and 1600 RPM using precise PWM control. Even at maximum speed, it generates an impressive 2.09 mmH2O of static pressure and over 77 CFM of airflow, while acoustic noise peaks at a remarkably quiet 29.2 decibels.
• Design & Ergonomics
Finished in a stark, matte white with brushed aluminum side accents, this fan elevates the aesthetic of any modern PC build. Anti-vibration rubber pads are pre-installed on all corners to prevent rattling against the metal chassis. Because this is the 140mm variant, it fills out large ATX and E-ATX cases beautifully, providing deeper, quieter airflow than standard 120mm alternatives.
• Compatibility / Use Cases
The SL140 V2 is universally compatible with standard 140mm fan mounts on PC cases, air coolers, and liquid cooling radiators. It is the definitive choice for hardcore gamers, custom water-cooling enthusiasts, and aesthetic-focused streamers building in premium showcase chassis like the Lian Li O11 Dynamic EVO or O11 Vision.
• Why This Product Stands Out
Standard RGB fans turn the back of your PC into a rat's nest of splitters and cables. The Lian Li SL140 V2 stands out by acting as modular building blocks. The upgraded 28mm thickness ensures it isn't just a "pretty" fan—it is a legitimate high-performance cooling engine that keeps flagship CPUs and GPUs from thermal throttling.
