5. Setup and Installation

Proper installation is crucial for optimal performance. Please refer to the detailed installation guide provided in your package for step-by-step instructions specific to your CPU socket. A general overview of the installation process includes:

1. Prepare Your System: Power down your computer and disconnect all cables. Remove your existing CPU cooler.
2. Install Backplate (if required): Attach the appropriate backplate to the rear of your motherboard, aligning it with the CPU socket holes.
3. Mount Radiator and Fans: Secure the radiator and pre-attached fans to an available mounting location in your PC case (e.g., top, front, or side). Ensure proper airflow direction.
4. Apply Thermal Paste: If not pre-applied, apply a small amount of thermal paste to the center of your CPU's integrated heat spreader (IHS).
5. Install Pump/Cold Plate: Carefully place the pump/cold plate assembly onto the CPU, aligning the mounting holes. Secure it with the appropriate screws and brackets for your CPU socket.
6. Connect Cables: Connect the pump's PWM cable to the CPU_FAN header on your motherboard. Connect the fan cables and RGB cables to the included controller, and then connect the controller to your motherboard's USB header and a SATA power connector. Ensure all connections are secure.
7. Software Installation: Download and install the Lian-Li L-Connect software from the official Lian-Li website to control the LCD display, fan speeds, and RGB lighting.

For detailed visual instructions, always consult the comprehensive installation manual included with your product.

6. Operating the Cooler and LCD Display

Once installed and powered on, the Lian-Li Galahad II LCD cooler will begin cooling your CPU. The integrated 2.88" IPS LCD screen on the pump block offers extensive customization options via the L-Connect software:

• System Monitoring: Display real-time CPU temperature, GPU temperature, fan speeds, and other system statistics.
• Custom Images & GIFs: Upload and display your favorite images or animated GIFs to personalize your system's aesthetic.
• Custom Text: Showcase custom text messages or system information.
• Lighting Effects: Synchronize the LCD's lighting with the SL-Infinity fans' ARGB effects.

Use the L-Connect software to configure these settings to your preference.

7. Maintenance

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

• Dust Removal: Periodically clean the radiator fins and fan blades using compressed air to remove dust buildup. Dust can impede airflow and reduce cooling efficiency.
• Inspect Tubing: Check the tubing for any signs of kinks, leaks, or damage. Ensure the connections to the pump and radiator are secure.
• Fan Inspection: Ensure all fans are spinning freely and quietly. Replace any fans that exhibit excessive noise or reduced performance.
• Software Updates: Keep the L-Connect software and firmware updated to benefit from performance improvements and new features.

Do not attempt to open the pump or radiator, as this will void the warranty and may cause damage.

8. Troubleshooting

If you encounter issues with your Lian-Li Galahad II LCD cooler, consider the following troubleshooting steps:

• No Power/No RGB:
  • Check all power connections, especially the SATA power to the controller.
  • Ensure the USB cable from the controller is securely connected to a motherboard USB header.
  • Verify that the L-Connect software is installed and running.
• High CPU Temperatures:
  • Confirm the pump is running (you may feel a slight vibration or hear a faint hum).
  • Ensure the cold plate is making proper contact with the CPU. Re-seat the cooler if necessary, and re-apply thermal paste.
  • Check fan orientation and ensure they are pushing air through the radiator effectively.
  • Clean any dust buildup on the radiator fins.
• LCD Screen Not Displaying:
  • Verify the USB connection from the pump to the controller and from the controller to the motherboard.
  • Ensure the L-Connect software is installed and updated.
  • Check for any error messages within the L-Connect software.
• Excessive Noise:
  • Identify if the noise is coming from the fans or the pump.
  • Adjust fan curves in the L-Connect software or BIOS to reduce fan speed.
  • If pump noise is excessive, ensure the pump is running at its recommended speed and that there are no air bubbles trapped in the loop (tilting the case gently may help dislodge them).

If issues persist after following these steps, please contact Lian-Li customer support.
