4. Operating the Cooler and LCD Display

The NZXT Kraken Z73 RGB's full functionality is managed through the NZXT CAM software.

1. Install NZXT CAM Software: Download and install the latest version of NZXT CAM from the official NZXT website (www.nzxt.com/cam).
2. Connect to CAM: Ensure the cooler's USB cable is connected to an internal USB 2.0 header on your motherboard. Launch the CAM software. The Kraken Z73 RGB should be automatically detected.
3. Monitor Performance: Use CAM to monitor CPU and liquid temperatures, pump speed, and fan speeds.
4. Customize LCD Display: Navigate to the 'Cooling' or 'Lighting' section within CAM to customize the LCD display. You can choose from various presets, upload custom images (JPG, PNG) or animated GIFs, and display real-time system information like CPU temperature, GPU temperature, or pump speed.

5. Adjust Fan and Pump Curves: Create custom fan and pump profiles to optimize cooling performance and noise levels based on your preferences and system load.
6. Control RGB Lighting: Adjust the RGB lighting effects and colors of the Aer RGB 2 fans through the CAM software.

5. Maintenance

Regular maintenance helps ensure optimal performance and longevity of your liquid cooler.

• Dust Cleaning: Periodically clean dust from the radiator fins and fan blades using compressed air. Ensure fans are not spinning during cleaning to prevent damage.
• Check Connections: Occasionally verify that all cables (power, USB, fan) are securely connected to prevent intermittent issues.
• Inspect Tubing: Check the liquid tubing for any signs of kinks, leaks, or damage.
• Software Updates: Keep your NZXT CAM software updated to benefit from performance improvements, new features, and bug fixes.

6. Troubleshooting

If you encounter issues with your Kraken Z73 RGB, consider the following common troubleshooting steps:

• Cooler Not Detected by CAM: Ensure the USB cable from the pump is securely connected to an internal USB 2.0 header on your motherboard. Try a different USB header if available. Reinstall NZXT CAM software.
• High CPU Temperatures: Verify that the pump is properly seated and making good contact with the CPU. Check that the pump and fans are receiving power and spinning. Ensure thermal paste application was adequate. Check fan orientation for proper airflow.
• Fans Not Spinning/RGB Not Working: Check all fan and RGB cable connections to the fan/RGB controller and motherboard. Ensure the fan/RGB controller is receiving power. Verify settings in NZXT CAM software.
• Unusual Noises: A slight gurgling sound upon initial startup is normal as air bubbles settle. If persistent, ensure the pump is mounted lower than the highest point of the radiator to prevent air from accumulating in the pump.
• LCD Display Issues: Ensure the USB connection is stable. Restart NZXT CAM. Update graphics drivers.
