4. Operating Considerations
Once your system is assembled, ensure proper operation by considering the following:
- Airflow: The mesh front panel is crucial for optimal air intake. Ensure no obstructions block the front panel or any fan vents.
- Fan Control: Utilize the included PWM ARGB control hub and your motherboard's fan control software to manage fan speeds and RGB lighting for balanced cooling and acoustics.
- Environmental Factors: Operate your PC in a well-ventilated area, away from direct sunlight or heat sources, to maintain stable temperatures.
5. Maintenance
Regular maintenance helps preserve your system's performance and extends component lifespan.
- Dust Filter Cleaning: The D502A features magnetic dust filters on the top and side, and a removable filter on the bottom. Regularly remove and clean these filters to prevent dust buildup inside the case.
- Internal Cleaning: Periodically use compressed air to clear dust from internal components, such as CPU coolers, GPU heatsinks, and fan blades. Ensure the system is powered off and unplugged before cleaning.
- Exterior Cleaning: Wipe the exterior of the case with a soft, damp cloth. Avoid abrasive cleaners.

- Verify all power cables (24-pin ATX, CPU, GPU, drives) are securely connected.
- Check front panel header connections (power button, reset button) to the motherboard.
- No Display:
- Confirm the monitor cable is connected to the graphics card (not the motherboard, unless using integrated graphics).
- Reseat the graphics card and RAM modules.
- Overheating:
- Ensure all case fans are spinning and oriented correctly for optimal airflow.
- Clean dust filters and internal components.
- Verify CPU cooler is properly seated and making good contact with the CPU.
- Fan/RGB Issues:
- Check connections to the fan hub and motherboard.
- Ensure fan control software or BIOS settings are configured correctly.
For more complex issues, consult your component manuals or seek professional assistance.
