Arctic Liquid Freezer III Pro 240 ARGB - White

The Arctic Liquid Freezer III Pro 240 comes with an extensive 6-year warranty.

Yes, the cooler includes a vial of ARCTIC MX-6 thermal paste (0.8g).

Yes, the included splitter cable allows for separate control of the pump, VRM fan, and radiator fans via individual PWM signals. Alternatively, you can use the all-in-one cable for synchronized control.

The 38mm radiator is thicker than conventional 27mm radiators, allowing it to hold more liquid and provide enhanced heat dissipation capabilities, leading to better thermal management, especially under heavy loads.

Yes, the Liquid Freezer III Pro 240 supports Intel LGA1851 and LGA 1700 sockets, as well as AMD Socket AM4 and AM5.

You will need at least 63mm of clearance in your PC case for the radiator and fan assembly.

To maintain optimal performance, periodically clean the radiator fins and fan blades using compressed air to remove dust buildup. Avoid using liquids directly on the components.

The integrated VRM fan provides active cooling for the motherboard's Voltage Regulator Modules (VRMs), helping to maintain stable power delivery to the CPU, especially during overclocking or sustained heavy workloads.

Check the pump's 4-pin PWM connection to the motherboard or controller. Ensure it is seated correctly. Verify the pump speed setting in your BIOS or software is not set to zero or off. Listen for any grinding sounds which may indicate a hardware issue.

Confirm the fan's 4-pin PWM connectors are securely plugged into the appropriate headers on the motherboard or controller. Check fan speed settings in your BIOS or control software; ensure they are not set to zero or disabled. Try connecting the fans to a different header to rule out a faulty port.

Verify that the thermal paste was applied correctly and evenly. Ensure the water block is making firm, even contact with the CPU. Check that the radiator and fans are clean and free of dust. Confirm the pump and fans are operating at adequate speeds via BIOS or control software.

Ensure the 3-pin RGB LED connector is properly plugged into a compatible motherboard header (e.g., JRGB or similar). Check your motherboard's RGB control software to ensure lighting is enabled and configured correctly. If using the ARGB variant, verify the connection to a 5V ARGB header.

Double-check case clearance requirements (minimum 63mm). Re-evaluate the mounting orientation of the radiator and fans. Consider alternative fan placement on the radiator if possible. For motherboard component interference (e.g., tall RAM or large M.2 coolers), review the offset mounting instructions and ensure correct bracket installation.
