PC enthusiast brand LIAN LI has unveiled two new fan models — the UNI FAN SL FLEX and CL FLEX — designed to deliver enhanced cooling performance and streamlined cable management. The new releases mark a significant step forward in modular fan technology, catering to builders who demand both aesthetics and efficiency.

Modular Design Meets Flexibility

The UNI FAN series has long been celebrated for its interlocking, daisy-chainable construction that reduces cable clutter. With the new SL FLEX and CL FLEX variants, LIAN LI doubles down on that philosophy, offering users more flexible mounting options and improved compatibility across a range of chassis.

Both models retain the signature clean, minimal look of the UNI family, but introduce subtle refinements that make installation easier and airflow more directed. Whether you're building a high-airflow rig or a liquid-cooled showpiece, these fans are engineered to fit seamlessly into modern setups.

What's New in the SL FLEX and CL FLEX

  • Enhanced blade geometry for optimized static pressure and airflow
  • Simplified daisy-chain system for faster, cleaner builds
  • Updated RGB lighting with smoother effects and more customization control
  • Improved anti-vibration pads for quieter operation

Built for Builders Who Value Clean Aesthetics

A major selling point for LIAN LI's UNI series has always been the ability to hide messy wiring. The new FLEX models continue that tradition, with a connector system that lets multiple fans link together using a single cable. This reduces the number of cables running across your motherboard tray and improves airflow inside the case.

For those who spend hours perfecting their cable management, the SL FLEX and CL FLEX are a welcome addition. They also come in both black and white colorways, making it easy to match any build theme — from stealthy dark setups to bright, showcase-ready rigs.

Cooling Performance That Keeps Up

While LIAN LI hasn't released full specs for the new fans, the company's track record suggests solid performance. The SL series has historically offered a good balance between noise levels and cooling capacity, and the FLEX variants are expected to maintain that reputation.

Builders using high-TDP processors or dense radiators will appreciate the static pressure optimization, which helps push air through tight fin stacks. The fans are also designed to operate smoothly at both low and high RPMs, giving users flexibility in tuning their cooling curves.

Compatibility and Ease of Installation

LIAN LI designed the UNI FAN SL FLEX and CL FLEX to be as user-friendly as possible. The fans ship with all necessary mounting screws and a controller hub (included in multi-pack versions), allowing for immediate out-of-the-box setup. The daisy-chain connectors are keyed to prevent incorrect insertion, so even first-time builders can install them without frustration.

Both models support motherboard sync via 3-pin ARGB headers, meaning they can be controlled using popular software from major motherboard brands. This makes integration into an existing RGB ecosystem straightforward — a key consideration for many enthusiasts.

Whether you're upgrading an existing rig or planning a fresh build, the new fans offer a compelling mix of style, function, and ease of use. Their release further cements LIAN LI's position as a leader in the PC cooling accessory market.

Key Takeaways

  • LIAN LI has introduced two new fan models: the UNI FAN SL FLEX and CL FLEX.
  • Both retain the modular, daisy-chain design that reduces cable clutter.
  • Enhanced blade design and anti-vibration features aim for better performance and quieter operation.
