ARGB Fan Control
The pre-installed ARGB fans can be synchronized with your motherboard's ARGB software for customizable lighting effects. Refer to your motherboard's manual for specific instructions on ARGB control software.
Maintenance
Regular maintenance ensures optimal performance and longevity of your computer case.
Dust Filters
The Elite 681 features full-size mesh openings on the top and bottom panels, which act as dust filters. Periodically remove and clean these filters to prevent dust buildup and maintain efficient airflow. Use compressed air or a soft brush to remove accumulated dust.
Tempered Glass Panels
Clean the tempered glass panels with a soft, lint-free cloth and a mild glass cleaner. Avoid abrasive materials or harsh chemicals that could scratch or damage the glass.
Troubleshooting
If you encounter issues during or after installation, consider the following common troubleshooting steps:
- No Power: Ensure all power supply cables are securely connected to the motherboard, graphics card, and other components. Check the power switch on the PSU and the case's power button connection to the motherboard.
- Fans Not Spinning/ARGB Not Working: Verify that all fan power cables and ARGB cables are correctly connected to the motherboard or a dedicated ARGB controller. Ensure motherboard ARGB software is installed and configured.
- Component Fit Issues: Double-check component dimensions against the case specifications. Ensure all standoffs are correctly installed for the motherboard size.
- Shipping Damage: Inspect the case for any physical damage that may have occurred during shipping, such as bent panels or broken support pieces, which could affect stability or component installation.
