- Connect to Fan Hub: Connect the 4-pin PWM cable from each fan to an available 4-pin fan header on the included ARGB Fan Hub.
- Connect ARGB Cables: Connect the 3-pin ARGB cable from each fan to an available 3-pin ARGB header on the fan hub. Ensure correct orientation to avoid damage.
- Connect Fan Hub to Motherboard:
- Connect the 4-pin PWM cable from the fan hub to a 4-pin PWM fan header on your motherboard (e.g., CPU_FAN, SYS_FAN). This allows for fan speed control.
- Connect the 3-pin ARGB cable from the fan hub to a 3-pin 5V ARGB header on your motherboard. This enables software control of the fan lighting. No connecteu a un connector RGB de 12V de 4 pins, ja que això danyarà els LED.
- Connect Fan Hub Power: Connect the SATA power connector from your power supply unit (PSU) to the ARGB Fan Hub. This provides power to both the fans and the ARGB lighting.
- Gestió de cables: Route all cables neatly to ensure proper airflow within the case and a clean aesthetic.

4. Instruccions de funcionament
4.1. PWM Fan Speed Control
The AX120 PRO fans utilize Pulse Width Modulation (PWM) technology, allowing your motherboard to dynamically adjust fan speeds based on system temperature. This provides an optimal balance between cooling performance and noise levels. Fan speeds can range from 600 to 1600 RPM.
- Control automàtic: Once connected to a 4-pin PWM header on your motherboard, the fan speed will be automatically regulated by your motherboard's BIOS/UEFI settings or operating system software.
- Ajust manual: Normalment podeu ajustar les corbes del ventilador i definir un pro de velocitat personalitzat.files through your motherboard's BIOS/UEFI or dedicated fan control software provided by your motherboard manufacturer.

4.2. Control d'il·luminació ARGB
The AX120 PRO fans feature Addressable RGB (ARGB) lighting, allowing for customizable lighting effects. The lighting is controlled via your motherboard's ARGB software.
- Software Synchronization: Connect the fan hub's ARGB cable to a compatible 3-pin 5V ARGB header on your motherboard. Use your motherboard's RGB control software (e.g., ASUS Aura Sync, GIGABYTE RGB Fusion 2.0, MSI Mystic Light Sync, ASRock Polychrome Sync) to customize lighting patterns, colors, and effects.
- Control independent: If your motherboard does not have an ARGB header, or if you prefer, a separate ARGB controller (not included) can be used to manage the lighting.
