- Intel: LGA 1700, LGA 1851
- AMD: AM5, AM4
2.3 Installation Steps (Intel LGA 1700/1851 Example)
- Prepare Motherboard: Ensure your motherboard is ready for cooler installation.
- Install Backplate: Attach the appropriate Intel backplate to the rear of your motherboard.
- Apply Thermal Paste: Apply a small amount of thermal paste to the center of your CPU.
- Remove Protective Film: Carefully peel off the protective film from the cold plate of the pump.
- Mount Pump/Blockhead: Align the pump/blockhead with the mounting holes on the motherboard and secure it using the provided screws. Tighten screws in a diagonal pattern to ensure even pressure.
- Mount Radiator: Install the 360mm radiator to an available mounting location in your PC case (e.g., top, front).
- Connect Cables: Connect the pump and fan cables to the appropriate headers on your motherboard (CPU_FAN, AIO_PUMP, ARGB headers).

3. Operating Instructions
3.1 ARGB Lighting Control (MSI Mystic Light)
The ARGB fans and pump head are compatible with MSI Mystic Light software. Download and install Mystic Light from the official MSI website to customize lighting effects, colors, and synchronization with other compatible components.

3.2 Fan and Pump Speed Control
Fan and pump speeds are typically controlled via your motherboard's BIOS/UEFI settings or through motherboard-specific software utilities. Adjust settings to balance cooling performance and noise levels according to your preference.
4. Maintenance
The MSI MAG Coreliquid A12 360 is designed for low maintenance. The evaporation-proof tubing minimizes coolant loss over time. Regular maintenance includes:
- Dust Removal: Periodically clean dust from the radiator fins and fan blades using compressed air to maintain optimal airflow and cooling efficiency.
- Inspect Tubing: Occasionally check the tubing for any signs of wear, kinks, or leaks.

5. Troubleshooting
If you encounter issues with your liquid cooler, consider the following common troubleshooting steps:
- No Power/Fans Not Spinning: Check all power connections to the pump and fans. Ensure they are securely plugged into the correct motherboard headers.
- High CPU Temperatures: Verify that the pump is running (you might feel a slight vibration or hear a faint hum). Ensure the cold plate has good contact with the CPU and that thermal paste was applied correctly. Check for dust buildup on the radiator.
- Unusual Noises: Listen for abnormal pump noises (e.g., grinding, gurgling). This could indicate air bubbles in the loop or a faulty pump. Ensure the radiator is mounted securely to prevent vibration noise.
- ARGB Not Working: Confirm ARGB cables are connected to the correct 3-pin 5V ARGB headers (not 4-pin 12V RGB headers). Use MSI Mystic Light software to troubleshoot and configure lighting.
