5. Operating Instructions
Once all components are installed and connected, you can power on your system. The M5 case features an integrated ARGB lighting system that can be synchronized with major motherboard technologies. Refer to your motherboard's manual for specific ARGB software and control instructions.
The pre-installed ARGB fans will illuminate upon power-on. Use your motherboard's software or a dedicated ARGB controller (if included or purchased separately) to customize lighting effects and fan speeds.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your PC case.
- Dust Filters: The M5 case includes dust filters to prevent dust buildup. Regularly clean these filters by removing them and gently brushing or washing away accumulated dust. Ensure they are completely dry before reinstallation.
- Tempered Glass Panels: Clean the tempered glass panels with a soft, lint-free cloth and a mild glass cleaner. Avoid abrasive materials that could scratch the surface.
- Internal Cleaning: Periodically use compressed air to clear dust from internal components and fans. Ensure the system is powered off and unplugged before cleaning.
7. Troubleshooting
If you encounter issues with your PC build, consider the following general troubleshooting steps:
- No Power: Ensure the PSU is correctly installed, switched on, and all power cables (24-pin, CPU, GPU) are securely connected to the motherboard and components.
- Fans Not Spinning/ARGB Not Working: Verify that all fan and ARGB cables are properly connected to the motherboard headers or ARGB controller. Check your motherboard's BIOS/UEFI settings or ARGB software for fan control and lighting settings.
- Component Fit Issues: Double-check component dimensions against the case specifications, especially for large GPUs, CPU coolers, and PSUs.
- Overheating: Ensure proper fan orientation for optimal airflow (intake/exhaust). Verify that CPU cooler and GPU fans are functioning correctly.
