Three-Fan Kit with Controller

The Lian Li UNI FAN SL-INF Flex 120 mm Reverse Blade ARGB 3-Pack Controller Black delivers three 120 mm case fans and a dedicated controller in a single package. It is built for PC builders who want coordinated airflow and lighting without sourcing parts separately. The reverse-blade design directs air in the opposite direction to standard fans for specialised cooling layouts.

Multi-Zone ARGB and Wireless Control

The bundled controller enables 5 V 3-pin ARGB management through motherboard software while fan speed runs via PWM or the L-Connect 3 wireless link. Updated LCD FLEX and LED FLEX receivers keep LCD functions active over the same wireless connection. This reduces cable clutter and lets builders choose between motherboard sync or software customisation for both lighting zones and fan curves.

Reverse Blade Airflow Direction

The defining specification is the reverse-blade orientation, which pushes air opposite to conventional 120 mm fans. Buyers who need standard airflow direction for typical intake or exhaust positions should select a different model. The three-fan count and included controller only suit builds planned around this reversed flow pattern.

商品問答

Will the ARGB lighting on these fans need the controller replaced if the motherboard header fails?

The included controller manages ARGB independently, so lighting stays functional even if the motherboard 5 V 3-pin header is unavailable.

What thermal limit appears first when the three fans run continuously at high PWM duty?

The 120 mm reverse-blade design moves air through the heatsink fins; sustained load will hit the case’s exhaust capacity before the fans reach their own thermal ceiling.

How much noise and heat does the wireless receiver add during all-day operation?

The receiver draws minimal power and produces no audible noise, so system acoustics and temperatures are dictated by the fans themselves, not the control link.
