Three Normal-Blade Fans with Wireless Controller

The pack contains three 120 mm normal-blade fans in white and a controller that connects wirelessly or by PWM. Builders who prefer a traditional push direction and want ARGB lighting synced to their motherboard can install them directly in a case. Buyers who need reverse-blade fans for a specific airflow path should choose a different model.

PWM or Wireless Speed Control with 5 V ARGB Sync

Fan speed is managed either through motherboard PWM headers or L-Connect 3 software, while lighting uses a 5 V 3-pin ARGB header for motherboard sync. The dual receiver design keeps wireless LCD functions active even when PWM is selected, reducing cable count inside the chassis. No acoustic or power-draw figures are supplied by the manufacturer.

Multi-Zone Edge Lighting on 120 mm Normal Blades

Each fan features a dual-style edge with multi-zone ARGB zones that create layered lighting depth across the 120 mm frame. The normal-blade orientation pushes air in the standard direction, so the visual effect matches the airflow pattern most builders expect. This specific lighting layout is the feature that distinguishes the SL-INF Flex from other UNI FAN variants.

Questions about this item

How do I connect the three fans and controller to my motherboard for both PWM speed control and 5V 3-pin ARGB lighting?

Daisy-chain the three fans together, then plug the combined PWM lead into a motherboard 4-pin header and the 5V 3-pin ARGB lead into a 5V 3-pin header; the included controller also accepts wireless L-Connect 3 commands if you prefer software control.

What parts will need cleaning or replacement after extended use?

Dust the fan blades and frame every few months with compressed air; the ARGB LEDs and motor are sealed and not user-serviceable, so only the entire fan would be replaced if it fails.

At what point does the 1.8-inch 400 x 400 60 Hz LCD on the receiver become the limiting factor during sustained operation?

The LCD receiver is rated for continuous 60 Hz refresh, so the first practical limit is usually thermal — if case airflow cannot remove heat from the three 120 mm fans, their PWM curves will throttle speeds before the display hits any bottleneck.
