3.3. Pump and Radiator Mounting
Mount the radiator to an available fan mount location in your PC case (typically top or front). Ensure adequate clearance for the radiator and fans. The pump block features an adjustable bracket design to ensure consistent contact pressure with your CPU for optimal thermal transfer. Apply thermal paste to your CPU if not pre-applied on the cooler's cold plate.

3.4. Cable Connections
Connect the pump and fan cables to the appropriate headers on your motherboard. The pump typically requires a dedicated AIO_PUMP or CPU_FAN header, while the fans connect to fan headers or a dedicated fan controller. Ensure all ARGB cables are connected to compatible ARGB headers for lighting control.

4.2. Software Control
Utilize the ASUS software (e.g., Armoury Crate) to gain full control over the cooler's performance and aesthetics. Key software features include:
- Adjusting pump and embedded fan speeds for optimal cooling and noise levels.
- Customizing ARGB lighting effects for the fans and pump block.
- Integrating with AIDA64 for advanced monitoring with special ROG themes.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your liquid cooler.
- Dust Removal: Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush. Accumulated dust can impede airflow and reduce cooling efficiency.
- Fan Inspection: Check fan blades for any obstructions or signs of wear. Ensure fans are securely mounted.
- Tubing and Connections: Inspect the tubing for any kinks, leaks, or damage. Ensure all cable connections are secure.
- Coolant (AIO): As an all-in-one closed-loop system, the cooler does not require coolant refills or maintenance. Do not attempt to open the loop.
6. Troubleshooting
If you encounter issues with your cooler, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| High CPU Temperatures | Insufficient thermal paste, poor contact with CPU, dust buildup on radiator, low pump speed, incorrect fan orientation. | Reapply thermal paste, reseat pump block, clean radiator/fans, increase pump/fan speeds via software, ensure fans are pushing air through radiator correctly. |
| Fans Not Spinning / ARGB Not Working | Loose cable connections, incorrect header connection, software issue. | Check all fan and ARGB cable connections. Ensure fans are connected to appropriate headers. Reinstall or update cooling software. |
| Pump Noise | Air bubbles in the loop, pump running at maximum speed. | Orient radiator higher than pump block to allow air to settle. Adjust pump speed via software to a lower, quieter setting if temperatures allow. |
| LCD Screen Not Displaying | Loose USB connection, software not running, driver issue. | Ensure USB cable from pump to motherboard is securely connected. Verify cooling software is running and updated. Check device manager for driver issues. |
