How to use
Install the AX140 PWM in your case or on a radiator using the appropriate mounting screws. Connect the fan power cable to a PWM-capable 4-pin fan header on the motherboard for automatic speed control, and connect the 5V 3-pin RGB header to a compatible motherboard RGB connector to control lighting through software. Ensure airflow direction aligns with your case cooling plan and secure anti-vibration pads contact surfaces to reduce resonance.
Usage recommendations
For optimal balance between cooling and noise, use PWM control to allow the motherboard to adjust fan speed according to temperature. When using the lighting, confirm your motherboard supports 5V 3-pin RGB and configure profiles in the manufacturer's RGB software. Periodically clean the fan blades to maintain airflow and prolong bearing life.
