4. Maintenance
4.1 Cleaning the Case
Regular cleaning helps maintain optimal performance and aesthetics:
- Exterior: Wipe the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners.
- Tempered Glass: Use a glass cleaner and a microfiber cloth for the tempered glass panel to prevent streaks.
- Dust Filters: Periodically remove and clean any dust filters (e.g., on the top, front, or bottom) to ensure unrestricted airflow. Use compressed air or rinse with water and allow to dry completely before reinstallation.
- Interior: Use compressed air to remove dust buildup from internal components and fan blades. Ensure the system is powered off and unplugged before cleaning the interior.

- Check Connections: Ensure all fan power cables and ARGB cables are securely connected to the motherboard or fan controller.
- Motherboard Settings: Verify fan control and ARGB settings in your motherboard's BIOS/UEFI or software.
5.2 System Overheating
- Airflow: Confirm that fans are installed with the correct orientation for intake and exhaust.
- Dust Buildup: Clean dust filters and internal components as described in the Maintenance section.
- Component Clearance: Ensure no cables or other obstructions are blocking airflow paths.
5.3 Front Panel Ports Not Functioning
- Internal Connections: Double-check that the front panel USB and audio cables are correctly connected to the corresponding headers on your motherboard.
