4. Operation

4.1 RGB Fan Control

The three pre-installed 120mm RGB fans can be controlled via your motherboard's RGB software if it has a compatible 4-pin 12V RGB header. A 1-to-3 splitter cable is included to connect all front fans to a single header. If your motherboard lacks an RGB header, an optional Cooler Master RGB controller (sold separately) may be required for full customization.

5. Maintenance

5.1 Dust Management

• The case includes a dust filter for the power supply. Regularly clean this filter to maintain optimal airflow and prevent dust buildup inside the system.

5.2 Tempered Glass Panel

• Clean the tempered glass side panel with a soft, lint-free cloth and a non-abrasive glass cleaner. Avoid harsh chemicals or abrasive materials that could scratch the glass.

5.3 General Cleaning

• Use compressed air to remove dust from internal components and fan blades. Ensure the system is powered off and unplugged before cleaning.

6. Troubleshooting

• No Power: Verify all power cables are securely connected to the power supply, motherboard, and components. Check the power switch on the PSU.
• Fans Not Spinning/RGB Not Lighting: Ensure fan power cables and RGB cables are correctly connected to the motherboard or controller. Check motherboard BIOS/UEFI settings for fan control.
• No Display: Confirm the graphics card is properly seated and connected to the power supply. Ensure the monitor cable is connected to the graphics card, not the motherboard's integrated graphics ports (unless using integrated graphics).
• Overheating: Ensure all fans are operating correctly and installed with proper airflow direction. Verify CPU cooler installation and thermal paste application. Check for obstructions to airflow.
