5.2 Fan Speed Control (PWM)

The fans utilize Pulse Width Modulation (PWM) technology, allowing your motherboard to precisely control fan speed based on system temperature. This ensures optimal cooling performance while minimizing noise levels.

• Connect the 4-pin PWM connector to a compatible header on your motherboard.
• Configure fan curves in your motherboard's BIOS/UEFI settings or through dedicated software to balance cooling and acoustics.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your AsiaHorse Dawn Pro fans.

• Cleaning: Periodically clean dust from the fan blades and frame using compressed air or a soft, dry cloth. Ensure the PC is powered off and unplugged before cleaning.
• Inspection: Check for any loose connections or obstructions that might impede fan rotation.

7. Troubleshooting

If you encounter issues with your Dawn Pro fans, consider the following common solutions:

7.1 Fans Not Spinning or Lighting Up

• Check Connections: Ensure all modular daisy chain connections are secure and the combo cable is firmly plugged into the last fan. Verify the PWM and ARGB cables are correctly connected to your motherboard or controller.
• Power Supply: Confirm your power supply is providing adequate power to the fan controller or motherboard headers.
• Motherboard Settings: Check your motherboard's BIOS/UEFI settings to ensure fan headers are enabled and configured correctly.
• Software Issues: If ARGB lighting is not working, ensure your motherboard's RGB software is installed, up-to-date, and correctly detecting the fans.

Improper connections are a common cause of issues. The following video highlights the importance of secure connections:

7.2 Excessive Noise

• Dust Buildup: Clean the fan blades and motor housing to remove any dust or debris.
• Loose Mounting: Ensure the fan is securely mounted and screws are tightened to prevent vibrations.
• Obstructions: Check for any cables or components touching the fan blades.
• Fan Speed: Adjust fan speed settings in your motherboard's BIOS/UEFI or software to a lower RPM if noise is a concern and temperatures allow.
