3. Setup and Installation
Before You Begin:
- Ensure your motherboard and PC case are compatible with a 360mm radiator.
- Turn off your computer and disconnect all power cables.
- Discharge any static electricity by touching a grounded metal object.
Component Overview:

Installation Steps:
- Prepare the Radiator and Fans: Attach the three 120mm ARGB fans to the radiator using the provided long screws. Ensure the fan airflow direction is appropriate for your case (intake or exhaust).
- Install Radiator: Mount the assembled radiator and fans into your PC case. Common mounting locations include the top or front of the case. Secure with screws.
- Prepare CPU Socket: Select the appropriate mounting brackets for your CPU socket (Intel LGA1700/1200 or AMD AM5/AM4). Follow the instructions in the included manual for specific bracket attachment to the pump and motherboard backplate installation.
- Apply Thermal Paste: If the CryoFuze thermal paste is not pre-applied to the coldplate, apply a small pea-sized amount to the center of your CPU's integrated heat spreader (IHS).
- Mount Pump/Coldplate: Carefully place the pump/coldplate assembly onto the CPU, aligning the mounting holes. Secure the pump to the motherboard using the appropriate screws and backplate. Ensure even pressure.
- Connect Cables:
- Connect the pump's 3-pin power cable to a dedicated AIO_PUMP or CPU_FAN header on your motherboard.
- Connect the fan PWM cables to the CPU_FAN header or a dedicated fan header on your motherboard, using the included splitter cable if necessary.
- Connect the ARGB cables from the fans and pump to a 3-pin 5V ARGB header on your motherboard or an external ARGB controller.

4. Operating Instructions
ARGB Lighting Control:
The ARGB lighting on the pump and fans can be controlled via your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome RGB) or a compatible external ARGB controller. Refer to your motherboard's manual for specific software instructions.

Fan Speed Control:
The 120mm PWM fans feature an adjustable speed range from 650 to 1,750 RPM (±10%). Fan speeds are typically controlled automatically by your motherboard based on CPU temperature, or manually adjusted through your motherboard's BIOS/UEFI settings or fan control software.

5. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your AIO liquid cooler:
- Dust Removal: Periodically clean dust from the radiator fins and fan blades using compressed air. Ensure the fans are not spinning during cleaning.
- Inspect Tubing: Check the tubing for any kinks, leaks, or signs of wear.
- Pump Noise: Listen for any unusual noises from the pump, which could indicate an issue.
- Thermal Paste: While CryoFuze thermal paste is designed for long-term stability, consider reapplying it if you notice a significant increase in CPU temperatures over time, especially after dismounting the cooler.
6. Troubleshooting
Common Issues and Solutions:
- No ARGB Lighting:
- Check if ARGB cables are securely connected to the motherboard header or controller.
- Ensure the ARGB header is 3-pin 5V (not 4-pin 12V RGB).
- Verify ARGB software settings on your motherboard.
- Fans Not Spinning or Spinning Slowly:
- Check fan PWM cable connections to the motherboard.
- Verify fan speed settings in BIOS/UEFI or fan control software.
- Ensure sufficient power delivery from the motherboard headers.
- High CPU Temperatures:
- Ensure the pump is running (check for vibrations or a faint hum).
- Verify the pump's power cable is connected to a constant power source (AIO_PUMP header).
- Check if the coldplate is making proper contact with the CPU. Re-seat the cooler if necessary, and reapply thermal paste.
- Ensure radiator fans are oriented correctly for optimal airflow (e.g., pulling air through the radiator).
- Clean any dust buildup on the radiator fins.
- Unusual Noise from Pump or Fans:
- For pump noise, ensure the pump is mounted correctly and not vibrating against other components.
- For fan noise, check for cable interference or loose fan screws. If a fan is excessively noisy, it may need replacement.
