3. Setup and Installation
Before beginning, ensure your system is powered off and disconnected from the power source. Refer to your motherboard manual for specific CPU socket information.
3.1. Prepare the CPU Socket
- Identify your CPU socket type (Intel LGA or AMD AM).
- For Intel sockets, install the appropriate backplate behind the motherboard. For AMD sockets, use the existing AMD backplate.
- Attach the correct standoffs to the motherboard according to your CPU socket.

3.2. Install the Radiator and Fans
The fans are pre-installed on the radiator for convenience. Choose a suitable mounting location in your PC case (top, front, or side) that supports a 360mm radiator.
- Secure the radiator to your chosen mounting location using the provided long screws. Ensure proper airflow direction (intake or exhaust) based on your case's cooling design.
- Connect the fan cables. The MAG CoreLiquid I360 features an 'EZ Connect' design for simplified fan wiring.

3.3. Mount the Pump Block
The pump block comes with pre-applied thermal paste. If you are reapplying thermal paste, ensure the CPU surface is clean and free of old paste.
- Carefully place the pump block onto the CPU, aligning the mounting holes with the standoffs.
- Secure the pump block with the appropriate thumb screws or nuts, tightening them in a diagonal pattern until snug. Do not overtighten.
- Connect the pump's 3-pin or 4-pin power cable to the designated CPU_FAN or AIO_PUMP header on your motherboard.
- Connect the ARGB cable from the pump block to an available 5V ARGB header on your motherboard or an ARGB controller.

4. Operating Instructions
Once installed, the MSI MAG CoreLiquid I360 operates automatically. The pump and fans will adjust their speeds based on CPU temperature, managed by your motherboard's BIOS/UEFI settings or dedicated software.
4.1. ARGB Lighting Control
The Addressable RGB (ARGB) lighting on the pump block and fans can be customized using MSI Mystic Light software or compatible motherboard RGB software. Ensure the ARGB cable is correctly connected to a 5V ARGB header.
- Download and install MSI Mystic Light from the official MSI website.
- Use the software interface to select desired lighting effects, colors, and synchronization options.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance 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.
- Tubing Inspection: Inspect the tubing for any signs of kinks, leaks, or damage. The evaporation-proof tubing is designed for durability, but regular checks are recommended.
- Fan Operation: Listen for any unusual noises from the fans or pump. If abnormal sounds occur, refer to the troubleshooting section.

6. Troubleshooting
If you encounter issues with your MSI MAG CoreLiquid I360, refer to the following common problems and solutions.
- High CPU Temperatures:
- Ensure the pump power cable is securely connected to the motherboard and receiving power.
- Verify that the pump block is properly seated on the CPU and tightened evenly.
- Check if fans are spinning and oriented correctly for optimal airflow.
- Clean any dust buildup on the radiator fins.
- Fans Not Spinning or ARGB Not Working:
- Check all fan and ARGB cable connections to the motherboard or controller.
- Ensure the 5V ARGB header is enabled in your motherboard's BIOS/UEFI.
- Verify that MSI Mystic Light or other RGB software is installed and configured correctly.
- Unusual Noise from Pump or Fans:
- Ensure no cables are obstructing fan blades.
- Check for air bubbles in the loop (this usually resolves itself over time).
- If pump noise is excessive, ensure it is running at an appropriate speed (check BIOS/UEFI settings).
