General Care
- Cleaning: Periodically clean the radiator fins and fan blades to prevent dust buildup, which can impede airflow and cooling performance. Use compressed air or a soft brush.
- Inspection: Regularly inspect tubing and connections for any signs of leaks or damage.
- Software Updates: Keep the MasterCTRL software updated to ensure optimal performance and access to the latest features.
Customization
Dual Cover Styles
The Atmos II LCD comes with two decorative top covers that attach magnetically, allowing you to easily switch styles to match your build's aesthetic.

Troubleshooting
- No Power/Fans Not Spinning: Ensure all power cables (4-pin PWM for fans, SATA power for pump/LCD) are securely connected to the motherboard and power supply. Check motherboard BIOS settings for fan control.
- High CPU Temperatures: Verify that the pump block is correctly seated on the CPU and that thermal paste was applied properly. Ensure fans are oriented correctly for optimal airflow (pushing or pulling air through the radiator). Check for dust buildup on the radiator.
- LCD Not Displaying/ARGB Not Working: Confirm that the USB cable for the LCD and ARGB cables are correctly connected to the motherboard. Ensure MasterCTRL software is installed and running. Check for driver updates for your motherboard's ARGB controller.
- Unusual Noises: A slight gurgling sound during initial startup is normal as air bubbles settle. If persistent or loud, check for proper mounting and ensure the pump is running at an adequate speed.
