The LIAN LI UNI FAN SL140 Black (UF-SL140-2B) is the cooling solution that revolutionized the custom PC industry. Before the UNI FAN, installing multiple RGB fans required routing dozens of messy power and lighting splitters behind the motherboard tray. Lian Li solved this by creating a patented, slide-in daisy-chain mechanism. By transmitting both PWM power and ARGB signals through physical contact pins on the fan frame, you can seamlessly link multiple fans together into a single, beautiful block of cooling power.
• Key Features
Revolutionary Daisy-Chain Design: Slide-in interlocking mechanisms allow you to physically link up to 4 fans in a single cluster, utilizing just one cable module to power the entire group.
UNI HUB Controller Included: This starter kit includes the essential L-Connect UNI HUB. It features 4 designated ports, allowing you to connect up to 16 UNI FANs simultaneously and sync them effortlessly.
Premium Edge Lighting: Each fan features 32 addressable RGB LEDs (16 on each side) shining through high-quality diffusers. This creates smooth, vibrant lines of light that remain visible from any angle inside your case.
Sandblasted Aluminum Trim: Unlike cheap plastic fans, the SL140 features beautiful sandblasted aluminum accents on the front and back of the frame, providing a premium, heavy-duty aesthetic that matches flagship PC chassis.
Fluid Dynamic Bearings (FDB): Engineered for silence and extreme durability. The FDB reduces friction, allowing the fan to spin at higher speeds without drawing excessive power or generating annoying motor whine.
L-Connect Software Integration: Control everything from your desktop. Toggle between custom fan curves, intense RGB lighting animations, or simply pass control over to your motherboard’s native RGB software with a single click.
• Performance / Technology
These 140mm fans are designed to move a massive volume of air quietly. Operating between 500 and 1500 RPM, the SL140 delivers up to 70.5 CFM of max airflow and 1.67 mmH2O of static pressure. Even under heavy gaming loads, the acoustic profile peaks at just 30 dB(A), making them the perfect intake or exhaust fans for large mid-tower and full-tower cases.
• Design & Ergonomics
Finished in a stealthy matte black, these fans blend perfectly into dark-themed builds while letting the bright ARGB edge lighting pop. The corners are equipped with thick, vibration-absorbing rubber pads that prevent acoustic resonance from transferring into your metal PC case, ensuring your gaming setup remains whisper-quiet.
• Compatibility / Use Cases
The SL140 fans are universally compatible with any PC case supporting standard 140mm fan mounts. Because this kit includes the UNI HUB controller, it serves as the perfect foundation for first-time PC builders, system integrators, and modders who want to build a fully synchronized, premium cooling ecosystem.
• Why This Product Stands Out
The Lian Li UNI FAN SL140 stands out because it completely respects the builder’s time. It turns a frustrating, one-hour cable management job into a satisfying two-minute snap-together process, yielding a cleaner, more professional-looking PC interior than any traditional wired fan on the market.
