The UNI FAN SL FLEX and CL FLEX have been upgraded with the new FLEX Receiver for more flexible connectivity and control. The compact receiver handles power delivery, RPM signal reporting, and supports either L-Connect 3 wireless control, or motherboard ARGB and PWM synchronization through a 5V 3-pin ARGB connection and PWM connection. Backward compatibility with existing SL Wireless and CL Wireless fans also makes the FLEX series easier to integrate across different builds.
