Troubleshooting
This section addresses common issues you might encounter.
System Not Powering On
- Check Power Connections: Ensure the power supply is connected to the wall and switched on. Verify all power cables from the power supply are correctly connected to the motherboard and components.
- Front Panel Connectors: Confirm that the power switch cable from the front I/O panel is correctly connected to the motherboard's front panel header. Refer to your motherboard manual for the correct pinout.
Poor Airflow or Overheating
- Dust Filters: Clean all dust filters as described in the Maintenance section. Clogged filters restrict airflow.
- Fan Operation: Ensure all case fans (front, rear, and any additional fans) are spinning correctly. Check their power connections.
- Cable Management: Poor cable management can obstruct airflow. Reorganize cables to allow for unobstructed air movement.
RGB Lighting Issues
- Controller Connection: Verify the RGB controller is properly connected to both the fans and the motherboard's RGB header.
- Software: Ensure your motherboard's RGB control software is installed and up-to-date.
