6. Operating Instructions
6.1. Powering On Your System
Once all components are installed and cables are connected, replace the side panels and connect the power cable to your PSU and a wall outlet. Press the power button on the top I/O panel to start your system.
6.2. ARGB Fan Control
The pre-installed darkFlash Air12X ARGB PWM fans offer brilliant lighting effects and precise speed control. Connect the ARGB and PWM cables from the fans to your motherboard's compatible headers. Use your motherboard's software or BIOS settings to customize fan speed and RGB lighting effects.
7. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your PC components.
7.1. Dust Filter Cleaning
The TH285 includes removable dust filters for practical maintenance. Periodically remove and clean these filters to prevent dust buildup, which can restrict airflow and increase component temperatures.
- Locate the dust filters (typically on the top, front, or bottom of the case).
- Gently remove the filters.
- Clean them using compressed air or by rinsing with water (ensure they are completely dry before reinstallation).
- Reinstall the dust filters.
7.2. General Cleaning
- Use a soft, dry cloth to wipe down the exterior of the case, including the tempered glass panels.
- For stubborn smudges on glass, use a glass cleaner applied to a cloth, not directly to the panel.
- Use compressed air to clear dust from internal components and fan blades.
8. Troubleshooting
If you encounter issues during or after assembly, consider the following common troubleshooting steps:
- System not powering on: Ensure all power cables (24-pin ATX, 8-pin CPU, GPU power) are securely connected. Verify the PSU switch is in the 'ON' position. Check front panel power button connections to the motherboard.
- No display output: Confirm the graphics card is fully seated in its PCIe slot and power cables are connected. Ensure the monitor cable is connected to the graphics card, not the motherboard's integrated graphics port (unless using integrated graphics).
- Fans not spinning or RGB not working: Check fan PWM and ARGB headers are correctly connected to the motherboard. Verify fan control software or BIOS settings.
- Overheating: Ensure all fans are oriented correctly for optimal airflow. Clean dust filters and internal components. Verify CPU cooler installation.
- Loose components: Double-check all screws and connections for components like the motherboard, GPU, and storage drives.
