- Exterior Cleaning: Wipe the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents.
5. Troubleshooting
This section addresses common issues you might encounter with your PC case.
5.1 Power Issues
- System not powering on:
- Ensure all power cables (24-pin ATX, 8-pin CPU, GPU power) are securely connected to the motherboard and components.
- Verify the PSU switch is in the 'ON' position.
- Check that the front panel power switch cable is correctly connected to the motherboard's F_PANEL header.
5.2 D-RGB Lighting Issues
- D-RGB not lighting up or incorrect colors:
- Ensure the D-RGB cables from the fans and LED strips are correctly connected to the integrated D-RGB controller.
- If using motherboard synchronization, ensure the D-RGB controller is connected to the motherboard's D-RGB header and that the motherboard's lighting software is configured correctly.
- Verify the D-RGB controller is receiving power (e.g., via SATA power connector).
- Try cycling through modes and colors using the front I/O buttons to rule out software issues.
5.3 Fan Noise or Malfunction
- Excessive fan noise:
- Check for dust buildup on fan blades and clean if necessary.
- Ensure fans are securely mounted and not vibrating against the chassis.
- Verify fan speeds are controlled appropriately by the motherboard or fan controller.
- Fan not spinning:
- Check fan power connections to the motherboard or fan hub.
- Ensure fan headers are enabled in the BIOS/UEFI settings.
