2. ARGB Fan Control

The pre-installed ARGB fans are connected to a fan hub. You can control the lighting effects in two ways:

• Case Button Control: Press the LED/Reset button on the top I/O panel to cycle through various pre-set ARGB lighting modes.
• Motherboard Software Control: If the fan hub is connected to your motherboard's ARGB header, you can synchronize and control the lighting effects using your motherboard's proprietary RGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion).

Maintenance

Dust Filter Cleaning

The BitFenix CETO case is equipped with magnetic dust filters on the top, bottom, and right steel panel. Regularly clean these filters to maintain optimal airflow and prevent dust buildup inside your system. Simply remove the filters, clean them with water or a soft brush, and ensure they are completely dry before reattaching.

General Cleaning

Use a soft, damp cloth to wipe down the exterior of the case. Avoid using harsh chemicals or abrasive materials that could damage the finish or tempered glass panels.

Troubleshooting

• Fans or ARGB lighting not working:
  • Ensure all fan and ARGB cables are securely connected to the fan hub and/or motherboard.
  • Verify the fan hub is receiving power (e.g., via SATA power connector).
  • If using motherboard software control, ensure the hub is correctly connected to the motherboard's ARGB header and the software is properly configured.
  • Try cycling through modes using the case's LED/Reset button to confirm basic functionality.
• Components not fitting:
  • Double-check the maximum supported dimensions for your components against the specifications section (e.g., GPU length, CPU cooler height, PSU length, radiator size).
  • Ensure correct motherboard form factor (ATX, mATX, Mini ITX) is being used and standoffs are correctly aligned.
• Poor Airflow:
  • Ensure all pre-installed fans are spinning correctly.
  • Clean dust filters regularly as described in the Maintenance section.
  • Verify proper fan orientation (intake/exhaust) for optimal airflow.
