6. Maintenance

To ensure optimal performance and longevity of your JONSBO T9 PC case, regular maintenance is recommended:

• Dust Cleaning: Periodically remove the side panels and use compressed air to clean dust from inside the case, especially from fan blades and heatsinks.

• Ventilation: Ensure the case's grille designs are not obstructed to maintain proper airflow and heat dissipation.

7. Troubleshooting

This section addresses common issues that may arise during assembly or operation:

• Components Not Fitting:
  • Verify that your motherboard is Mini ITX.
  • Check GPU length compatibility, especially if a 3.5" HDD is installed (max 202mm with HDD, 310mm without).
  • Ensure CPU cooler height is within the limits for the selected motherboard level (58mm, 68mm, or 78mm).
  • Confirm PSU is SFX type and within 100mm length.
• Poor Airflow/Overheating:
  • Ensure all internal cables are neatly routed to avoid obstructing airflow.
  • Consider installing an optional 120mm top fan for improved exhaust.
  • Clean dust from components and case grilles regularly.
• System Not Powering On:
  • Double-check all power connections to the motherboard, CPU, GPU, and storage drives.
