Arctic Liquid Freezer III Pro 420 ARGB AIO Liquid Cooler - White

It supports Intel LGA 1700 and LGA 1851 sockets, and AMD Socket AM4 and AM5.

You will need at least 63 mm of clearance. The radiator itself is 38 mm thick, and the fans add additional depth.

Yes, you can use the included splitter cable to control the pump, VRM fan, and radiator fans separately. Alternatively, you can synchronize them using a single PWM signal via the all-in-one cable.

Yes, the cooler comes with pre-applied MX-6 Thermal Paste for straightforward installation.

The VRM fan actively cools the voltage regulator modules on your motherboard, which helps to improve overall system stability, especially under heavy loads or during overclocking.

Arctic provides a compatible M.2 cooler free of charge for affected motherboards. Contact Arctic support for assistance.

Use compressed air or a soft brush to remove dust from the radiator fins and fan blades periodically. This ensures optimal airflow and cooling performance.

Ensure the pump power cable is securely connected to the motherboard or controller. Check the pump speed setting in your BIOS or software; it should not be set to zero. Verify the pump is not obstructed.

Confirm fan cables are correctly connected to the motherboard headers or the provided splitter/all-in-one cable. Check fan speed settings in the BIOS/software; they might be set to 0 RPM in idle modes. Ensure no physical obstruction is preventing fan rotation.

Verify that the cold plate is making even contact with the CPU and that the mounting pressure is correct. Ensure thermal paste was applied properly. Check that the radiator and fans are clean and unobstructed. Confirm the pump and fans are running at sufficient speeds.

Ensure the RGB cables are properly connected to the motherboard's RGB header or a compatible controller. Check if the RGB software on your system is running and configured correctly. Try connecting the RGB cable to a different header or controller to test.

This often indicates inadequate cooling. Re-check all installation steps, thermal paste application, fan and pump connections, and ensure sufficient case airflow. Monitor temperatures using monitoring software.
