1.8″ LCD Display

Expanded LCD, Enhanced Visuals

A newly designed 1.8″ LCD with a refined narrow-bezel design, 400 × 400 resolution and a 60Hz refresh rate. Full blade coverage delivers crisper visuals and greater creative freedom for personalised displays.

Supports MP4, GIF, JPG and PNG content.

Dual-Sided Frame

Asymmetrical Design, Infinite Depth

The SL-INF FLEX series features a dual-sided frame design — an angled pattern on one side, a dual-rectangle design on the other. Layered lighting effects create a richer, more dimensional visual experience from any viewing angle.

Three independently controlled lighting zones: fan blade, side infinity mirror and edge lighting.

Reverse Blade · FLEX Receiver

Reverse Blade. Flexible Installation.

This reverse-blade model is built for intake-oriented airflow while keeping the infinity-mirror face visible. The included FLEX receiver adapter lets you change frame orientation while keeping the original connection direction.

LCD FLEX Receiver ×1
USB + ARGB Cables

Important: The receiver and adapter must always be installed together on the same side. Do not install the receiver on one end and the adapter on the opposite end — this will cause connection issues.

Control Insight

Three Control Modes

Control the FLEX series with L-Connect 3 via USB, sync lighting through your motherboard 5V 3-Pin ARGB, or go fully wireless with the optional L-Wireless Controller. LCD Triple Packs do not include an L-Wireless Controller — the single pack requires it separately for Wireless Mode.

FDB Bearing · Enhanced Design

Engineered for Performance, Built for Cooling

An engineered oil retention groove around the fan bearing keeps lubricant precisely where it’s needed — reducing friction, lowering noise and extending long-term bearing reliability.

Frequently Asked Questions

What does the “Reverse Blade” version mean?

Reverse-blade fans are designed so that the infinity-mirror face remains visible when the fan is used in an intake orientation. This lets you achieve a consistent visual look on both sides of a case without compromising airflow direction.

Do I need the L-Wireless Controller for the LCD screen?

No. The single-pack LCD FLEX fan includes a 9-Pin USB cable for L-Connect 3 control. The L-Wireless Controller is optional for L-Connect 3 software control, but required for Wireless Mode. LCD Triple Packs do not include an L-Wireless Controller.

Can I sync this fan with my motherboard’s ARGB?

Yes. Connect the included 5V 3-Pin ARGB cable to unify fan lighting with your motherboard RGB ecosystem. For LCD fans, first connect via USB to L-Connect 3 to set the default offline theme — once saved, the content remains active so you can switch to the ARGB cable for independent lighting control.

How should the FLEX Receiver and adapter be installed?

The receiver and adapter must always be installed together on the same side. Do not install the receiver on one end and the adapter on the opposite end — this configuration will result in connection issues.

Can I expand this with existing UNI FAN SL-INF Wireless fans?

Yes. Existing UNI FAN SL-INF Wireless fans can be used with the SL-INF FLEX Receiver, allowing you to expand or upgrade your setup without purchasing additional fans or another L-Wireless Receiver.

What LCD content formats are supported?

The 1.8″ LCD supports MP4, GIF, JPG and PNG content at 400 × 400 resolution with a 60Hz refresh rate. Wireless Mode offers 29 built-in LCD preset themes, including clock displays and real-time system monitoring layouts.
