3. Setup and Installation

Before starting, ensure you have all necessary components and tools. Handle all parts with care, especially the glass panel. Do not remove the curved-glass explosion-proof film.

3.1 Motherboard Installation

1. Carefully remove the side panels to access the interior of the case.
2. Install the necessary motherboard standoffs for your ATX, Micro-ATX, or ITX motherboard.
3. Align your motherboard with the standoffs and I/O shield, then secure it with screws. For BTF motherboards, ensure all back-plug connections are accessible and properly aligned.

3.2 Cooling System Installation (Fans & AIO)

The TK-3 supports extensive cooling configurations.

• Fan Positions:
  • Top: 3x 120mm or 2x 140mm fans
  • Bottom: 3x 120mm fans
  • Motherboard Side: 3x 120mm fans
  • Rear: 1x 120mm fan
• AIO Support:
  • Top: 360mm or 280mm AIO
  • Bottom: 360mm AIO

Install fans or AIO radiators in the desired positions, ensuring proper airflow direction. The case is designed for vertical upward airflow to prevent heat accumulation.

4. Operation

Once all components are installed and secured, connect your peripherals and power cable. Press the power button on the front panel to start your system.

4.1 Airflow Management

The JONSBO TK-3 is designed with a vertical upward airflow path to minimize heat accumulation. Ensure your installed fans are oriented correctly to facilitate this airflow. Bottom intake fans and top/rear exhaust fans are generally recommended for optimal cooling performance.

5. Maintenance

Regular maintenance helps ensure the longevity and performance of your PC components.

• Dust Cleaning: Periodically clean dust filters (if present) and internal components using compressed air. Ensure the system is powered off and unplugged before cleaning.
• Glass Panel Care: Clean the curved glass panel with a soft, lint-free cloth and a mild glass cleaner. Avoid abrasive materials that could scratch the surface.
• Cable Management: Periodically check cable routing to ensure no cables are obstructing airflow or fan operation.

6. Troubleshooting

This section addresses common issues you might encounter during assembly or operation.

• Component Fit Issues: If a component (e.g., large GPU, CPU cooler) does not fit, double-check the maximum supported dimensions listed in the specifications. Ensure all cables are routed efficiently to avoid obstruction.
• Poor Airflow/High Temperatures: Verify that all fans are installed in the correct orientation (intake/exhaust) and that dust filters are clean. Ensure no cables are blocking airflow paths.
• Front Panel I/O Not Working: Check all front panel header connections to the motherboard. Ensure they are securely seated and connected to the correct pins as per your motherboard manual.
• Loose Screws/Panels: Ensure all screws, especially for the glass panels, are tightened gently but firmly. Avoid over-tightening to prevent stripping.

If you encounter persistent issues, refer to your individual component manuals or contact JONSBO customer support.
