Operating Instructions

Once all components are installed and connected, ensure all cables are properly routed and secured. Power on your system using the power button on the front I/O panel.

Thermal Design and Airflow

The Q300L V2 features an open thermal design with perforated front, top, and bottom panels. This design promotes excellent heat dissipation and optimal thermal airflow throughout the system. Ensure that fan orientations are set to create an effective airflow path (e.g., front intake, rear/top exhaust) for best performance.

Maintenance

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

Dust Filter Cleaning

The Q300L V2 is equipped with redesigned magnetic patterned dust filters on the front, top, and bottom panels. These filters are easily removable for cleaning. Periodically remove and clean them with compressed air or by rinsing with water (ensure they are completely dry before reinstallation) to prevent dust buildup and maintain airflow.

General Cleaning

Wipe the exterior of the case with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish or tempered glass. For the interior, use compressed air to remove dust from components.

Troubleshooting

If you encounter issues with your PC build, consider the following common troubleshooting steps:

• System Not Powering On:
  • Ensure the power supply is switched on and properly connected to the wall outlet and motherboard.
  • Verify all front panel connectors (power switch, reset switch) are correctly attached to the motherboard headers.
  • Check that the CPU power and main ATX power cables are securely connected.
• No Display Output:
  • Confirm the monitor cable is connected to the graphics card (not the motherboard integrated graphics, unless no dedicated GPU is present).
  • Reseat the graphics card in its PCIe slot.
  • Check that the graphics card has sufficient power from the PSU.
• Overheating Issues:
  • Ensure all case fans and CPU/GPU coolers are spinning correctly.
  • Verify fan orientations for optimal airflow (intake/exhaust).
  • Clean dust filters and internal components to remove any obstructions.
  • Check thermal paste application on the CPU cooler.
• USB Ports Not Functioning:
  • Ensure the USB headers from the front I/O panel are correctly connected to the motherboard.
  • Check motherboard drivers for USB controllers.

For more detailed troubleshooting, refer to the manuals for your specific motherboard, CPU, and graphics card.
