4. Operating Instructions
4.1. Powering On
Once all components are installed and cables are connected, close the side panel. Connect your monitor, keyboard, mouse, and power cable to the PSU. Press the power button on the front I/O panel to start your system.
4.2. ARGB Lighting Control
The included ARGB fans are typically controlled via your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion). Connect the ARGB cables from the fans to the appropriate headers on your motherboard. Refer to your motherboard manual for specific software instructions.
4.3. Fan Speed Control (PWM)
The PWM fans automatically adjust their speed based on system temperature, controlled by your motherboard's fan headers. You can fine-tune fan curves through your motherboard's BIOS/UEFI settings or dedicated software.
5. Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your PC components.
5.1. Dust Filter Cleaning
The Arian Frame A400 includes removable dust filters. Periodically remove and clean these filters to prevent dust buildup inside the case, which can hinder airflow and cooling efficiency.
- Gently slide out the filters.
- Clean them with a soft brush or rinse with water (ensure they are completely dry before reinstallation).
5.2. Tempered Glass Panel Cleaning
Use a microfiber cloth and a non-abrasive glass cleaner to clean the tempered glass panel. Avoid harsh chemicals that could damage the glass or coatings.
5.3. Internal Dust Removal
Every few months, open the case and use compressed air to gently remove dust from internal components, especially fan blades, heatsinks, and radiator fins.
6. Troubleshooting
If you encounter issues, consider the following common troubleshooting steps:
- No Power: Ensure the PSU is switched on, the power cable is securely connected, and all internal power cables (24-pin ATX, 8-pin CPU, GPU power) are properly seated.
- Fans Not Spinning/ARGB Not Working: Check fan and ARGB cable connections to the motherboard or controller. Verify that ARGB software is correctly configured.
- Overheating: Ensure all fans are spinning correctly and dust filters are clean. Verify proper installation of CPU cooler and thermal paste.
- Front Panel I/O Issues: Double-check the small front panel header connections to the motherboard (power switch, reset switch, USB, audio).
For persistent issues, consult your component manuals or contact Abysm Gaming support.
