5. Setup and Installation
Follow these steps to install your Aigo AR12PRO fans and controller:
- Mounting the Fans: Secure the fans to your PC case or radiator using appropriate screws. Ensure the fan's wind direction indicator (arrow on the side) points towards the desired airflow (front is air inlet, back is air outlet).
- Shock Absorption: The fans are equipped with soft material damping pads. Ensure these pads are properly seated to minimize vibration and noise.
- Controller Placement (if applicable): If using the APC1 ARGB controller, choose a suitable location inside your PC case. Use the provided double-sided Velcro to secure the controller.

6. Wiring Diagram
Proper wiring is crucial for the functionality of your fans. Refer to the diagrams below for correct connections.
6.1 Fan to Fan Connection (Series)
The AR12PRO fans can be connected in series. Each fan has a 4-pin PWM male and female connector, and a 5V A-RGB 3-pin male and female connector. Connect the male connector of one fan to the female connector of the next fan in the chain.

6.2 Controller Connection (if applicable)
If you are using the APC1 ARGB controller, connect the fans to the controller's ARGB and PWM ports. The controller requires SATA power from your power supply.

6.3 Motherboard Connection
Connect the 4-pin PWM cable from the last fan in the series (or directly from a single fan) to a 4-pin fan header on your motherboard. For ARGB lighting, connect the 5V 3-pin ARGB cable to a compatible 5V 3-pin ARGB header on your motherboard. Do NOT connect to a 12V 4-pin RGB header, as this will damage the LEDs.

7. Operating Instructions
7.1 Fan Speed Control (PWM)
The AR12PRO fans utilize PWM technology, allowing your motherboard or fan controller to dynamically adjust fan speed based on system temperature. This ensures efficient cooling when needed and quiet operation during lighter loads.
7.2 ARGB Lighting Control
- Motherboard Sync: If connected to a compatible 5V 3-pin ARGB header on your motherboard, you can control the lighting effects using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion).
- Controller & Remote: If using the APC1 ARGB controller, you can control the lighting effects using the included remote control. The remote allows you to change colors, modes, and brightness.
- Reset Button Jumper: The controller may also offer a 'RESET SW' jumper. This allows you to connect your PC case's reset button to the controller to cycle through ARGB modes without needing the remote.

8. Maintenance
To ensure optimal performance and longevity of your Aigo AR12PRO fans, regular maintenance is recommended:
- Cleaning: Periodically clean the fan blades and frame to remove dust buildup. Use a can of compressed air or a soft brush. Ensure the fan is powered off before cleaning.
- Inspection: Check cables for any signs of wear or damage. Ensure all connections are secure.
9. Troubleshooting
- Fans not spinning:
- Check if the 4-pin PWM cable is securely connected to the motherboard or controller.
- Ensure the power supply (SATA connector for controller) is properly connected and receiving power. - RGB lights not working or incorrect colors:
- Verify that the 5V 3-pin ARGB cable is correctly connected to a compatible 5V 3-pin ARGB header on your motherboard or to the controller.
- DO NOT connect to a 12V 4-pin RGB header. This will damage the LEDs.
- If using a controller, ensure it is powered and the remote control has a working battery. - Excessive noise:
- Check for any obstructions preventing the fan blades from spinning freely.
- Ensure the fan is securely mounted and the shock absorption pads are in place.
- If the noise is a grinding sound, the bearing might be faulty.
10. User Tips
- If your motherboard does not have a 5V 3-pin ARGB sync interface, consider purchasing a fan kit that includes a dedicated controller to manage the RGB lighting effects.
- When connecting multiple fans, ensure they are daisy-chained correctly to avoid overloading any single port.
- For optimal cooling, ensure proper airflow direction within your PC case. Fans typically have an arrow indicating airflow direction.
11. Warranty and Support
The warranty period for Aigo fans is typically 1 year. For any issues or support, please contact the seller or manufacturer directly.
