Setup
Follow these steps to properly install your GAMDIAS AEOLUS M2 1203 LITE fans:
1. Physical Installation
- Identify the desired mounting locations in your PC case or on your radiator. Ensure proper airflow direction (intake or exhaust) as per your system's cooling design.
- Align each fan with the screw holes.
- Secure each fan using the provided mounting screws. Do not overtighten.
2. Wiring Connections
The AEOLUS M2 1203 LITE fans require two connections: one for power and one for RGB lighting control.
- Fan Power: Connect the Molex connector from each fan to an available Molex power connector from your power supply unit (PSU).
- RGB Lighting: Connect the 5V-3pin ARGB connector from each fan to an available 5V-3pin Addressable RGB header on your motherboard or a compatible ARGB controller.
Important Note on RGB Connection:
The AEOLUS M2 1203 LITE fans support only 5V-3pin Addressable RGB (digital). Connecting them to a 12V-4pin RGB header will damage the LEDs and void your warranty. Always verify your motherboard's RGB header type before connecting.

Operating Instructions
Once installed and connected, the fans will begin operating when your PC is powered on. The RGB lighting can be controlled via your motherboard's software or a dedicated ARGB controller.

RGB Lighting Control
The AEOLUS M2 1203 LITE fans feature trio RGB rings with up to 30 chromatic lighting effect options, including Rainbow, multicolor, and the ability to turn LEDs off. Control is typically achieved through:
- Motherboard Software: If connected to a compatible 5V-3pin ARGB header, you can use software like ASUS Aura Sync, MSI Mystic Light, or GIGABYTE RGB Fusion to customize lighting effects and synchronize them with other components.
- ARGB Controller: If your motherboard lacks an ARGB header, or if you prefer a dedicated solution, connect the fans to an external ARGB controller (sold separately) to manage lighting effects.
Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your fans.
- Cleaning: Periodically clean the fan blades and housing to remove dust buildup. Use compressed air or a soft brush. Ensure the PC is powered off and unplugged before cleaning.
- Inspection: Check fan cables for any signs of wear or damage. Ensure all connections remain secure.
- Avoid Liquids: Do not use liquid cleaners directly on the fans or their electrical components.
Troubleshooting
If you encounter issues with your GAMDIAS AEOLUS M2 1203 LITE fans, refer to the following common problems and solutions:
- Fans Not Spinning:
- Ensure the Molex power connector is securely plugged into both the fan and the PSU.
- Check if your PSU is providing power.
- RGB Lighting Not Working:
- Verify the 5V-3pin ARGB connector is correctly and securely attached to the motherboard or controller.
- Confirm you are using a 5V-3pin ARGB header, not a 12V-4pin RGB header.
- Check your motherboard's RGB software or ARGB controller settings to ensure lighting is enabled and configured.
- Ensure the RGB cable is not damaged.
- Incorrect RGB Colors/Effects:
- Update your motherboard's RGB software to the latest version.
- Reset RGB settings in your software or controller.
- Ensure all fans are connected to the same ARGB channel if using a controller, or configured correctly in software.
