Lian Li UNI FAN SL FLEX Reverse Blade Fan: Cooling with a visible front
Lian Li UNI FAN SL FLEX Reverse Blade 120 mm
With an airflow of up to 110.5 m³/h and a static pressure of 2.13 mmH₂O, the Lian Li UNI FAN SL FLEX Wireless Reverse Blade is suitable for various cooling tasks. The reverse blade design reverses the direction of the airflow. This means the visible fan side remains facing inward even when installed as an intake fan.

Connect multiple fans directly to each other
Connection of the UNI FAN SL FLEX Reverse Blade
Integrated contacts in the fan frame allow multiple UNI FAN SL FLEX fans to be connected directly to each other. Power and control signals are passed along within the fan group. This reduces the number of individual cables needed and makes installing multiple fans easier.

Each fan comes with a FLEX receiver. Fan speed and lighting can be controlled via the 4-pin PWM connector and the integrated 2.4 GHz wireless connection. Alternatively, you can use the included 3-pin ARGB cable and manage the fan through your motherboard’s headers.

Control with L-Connect 3
In combination with L-Connect 3, you can manage fan speed and ARGB lighting. You can create custom fan curves and adjust the colors and effects of the side lighting to match your system.

- ARGB lighting with side infinity mirrors
- Infinity mirrors on both sides
- Side light strips with diffusers
- Various colors and effects possible
- Reverse blade for a clear view of the front side

There is an infinity mirror on both sides of the fan frame. Additional light strips with diffusers frame the mirrored surfaces. The mirrors and light strips can be illuminated in different colors and with various effects.

For gaming PCs and custom builds
The Lian Li UNI FAN SL FLEX Wireless Reverse Blade 120 mm combines cooling, flexible control and side ARGB lighting. The reverse blade design is especially suitable for intake fans whose visible front side should face into the interior. The daisy-chain system simultaneously reduces the number of individual cables.

About Us

Founded in 2004, WatercoolingUK began at a time when custom watercooling was still niche, experimental, and driven by passionate PC enthusiasts. Back then, liquid cooling was all about pushing boundaries - achieving lower temperatures, near silent operation, and builds that simply looked incredible.

From day one, we've supported both grassroots innovators and globally recognised manufacturers. We were early adopters and champions of brands that have since become industry leaders, including XSPC, EKWB, and Hardware Labs. Over the years, we've helped shape the UK watercooling scene into the thriving market it is today.

What started as a small eBay store quickly grew into a full-scale eCommerce operation, and with over 20 years of trading experience, we've continued to evolve alongside the industry. Today, as the UK's largest dedicated watercooling supplier, we offer the widest range of components, expert knowledge, and outstanding value - serving gamers, enthusiasts, professionals, and showcase builders alike.
