Setup and Installation

Before beginning installation, ensure your system is powered off and disconnected from the power source. Refer to your motherboard's manual for specific CPU socket mounting instructions if needed.

CPU Socket Compatibility:

• Intel: LGA 1200, 1150, 1151, 1152, 1155, 1156, 1366
• AMD: AM4

Installation Steps:

1. Prepare the CPU: Ensure your CPU is clean and free of old thermal paste. The cooler comes with pre-applied thermal paste.
2. Install Mounting Brackets: Attach the appropriate mounting brackets for your CPU socket to the pump unit.
3. Mount Radiator and Fan: Secure the 120mm radiator and fan to an available fan mount in your PC case. Ensure proper airflow direction (typically exhausting air out of the case).
4. Secure Pump to CPU: Carefully place the pump unit onto the CPU, aligning it with the mounting holes. Tighten the screws in a criss-cross pattern until snug.
5. Connect Cables: Connect the pump power cable to the AIO_PUMP header on your motherboard. Connect the fan cable to the CPU_FAN or CHA_FAN header. Connect the RGB cable to a compatible 4-pin RGB header on your motherboard for lighting control.

Operating Instructions

Once installed, the ASUS TUF Gaming LC 120 RGB cooler operates automatically to maintain optimal CPU temperatures.

• Fan Control: The radiator fan speed is typically controlled by your motherboard's BIOS/UEFI settings or through ASUS software (e.g., Armoury Crate) if available. Ensure fan curves are set to provide adequate cooling under load.
• RGB Lighting: The RGB lighting on the pump and fan can be customized using ASUS Aura Sync software. Connect the RGB cable to a compatible 4-pin RGB header on your motherboard to enable synchronization and control.
• Noise Level: The cooler is designed for efficient operation with a typical noise level of 29 Decibels.

Maintenance

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

• Dust Removal: Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush. Excessive dust can impede airflow and reduce cooling efficiency.
• Tubing Inspection: Inspect the reinforced, sleeved tubing for any signs of wear, kinks, or leaks. While designed for durability, regular checks are recommended.
• Pump Unit: Ensure the pump unit remains securely mounted to the CPU. No user-serviceable parts are inside the pump unit.

Troubleshooting

• High CPU Temperatures:
  • Verify that the pump is running and connected correctly to the AIO_PUMP header.
  • Ensure the fan is spinning and connected to the CPU_FAN or CHA_FAN header.
  • Check that the pump unit is securely mounted to the CPU and making good contact.
  • Confirm that the thermal paste application is adequate (the cooler comes with pre-applied paste, but reapplication might be necessary if re-seating).
  • Ensure proper airflow within your PC case, with the radiator fan correctly oriented.
  • Note that a 120mm AIO cooler may not be sufficient for heavily overclocked high-end CPUs. Consider your CPU's thermal design power (TDP) and cooling requirements.
• RGB Lighting Not Working:
  • Check that the RGB cable is securely connected to a compatible 4-pin RGB header on your motherboard.
  • Ensure ASUS Aura Sync software is installed and configured correctly.
• Missing Parts:
  • Carefully check all packaging materials for small components. If parts are genuinely missing, contact ASUS customer support.
