5. Maintenance

5.1. Cleaning the Case

Regularly clean the exterior of the case with a soft, damp cloth. Avoid abrasive cleaners. For internal cleaning, power off and unplug the system. Use compressed air to remove dust from fans, heatsinks, and internal components. Pay special attention to the perforated front bezel and fan filters to maintain optimal airflow.

5.2. Fan Maintenance

Periodically check fan blades for dust buildup. If a fan becomes excessively noisy or stops spinning, it may require cleaning or replacement. Ensure fan cables are not obstructing fan rotation.

6. Troubleshooting

6.1. System Not Powering On

• Ensure the power cable is securely connected to both the PSU and the wall outlet.
• Verify the PSU's power switch is in the 'ON' position.
• Check that the front panel power button cable is correctly connected to the motherboard's header.
• Confirm all internal power connections (24-pin ATX, CPU, GPU) are secure.

6.2. Excessive Fan Noise

• Check for dust buildup on fan blades and clean them.
• Ensure no cables are interfering with fan rotation.
• Adjust fan speeds using the 3-speed switches to a lower setting if noise is a concern and temperatures allow.

6.3. Overheating Issues

• Ensure all case fans are spinning correctly and are oriented for proper airflow (intake/exhaust).
• Clean any dust from fan filters and heatsinks.
• Verify that fan speed switches are set to a higher cooling performance setting.
