Product identity

The ARCTIC Liquid Freezer III 360 A-RGB is an all-in-one liquid CPU cooler designed for desktop systems. It uses a 12 volt PWM-controlled pump and three radiator fans that operate between 200 and 1800 RPM, with a maximum rotational speed of 2500 RPM. The aluminium radiator measures 360 mm and includes integrated cable management that routes fan wires inside the tubing jacket for a single motherboard connection.

Installation experience

Mounting hardware supports LGA1700 and LGA1851 sockets using an Intel contact frame that improves pressure distribution across the CPU heat spreader. A native 5 mm offset mount is provided for Ryzen processors to align the cold plate with chiplet hotspots. The manual warns that oversized coolers may interfere with the M.2_1 slot on some motherboards, so clearance should be verified before installation. A PWM-controlled VRM fan on the pump block adds active cooling for voltage converters around the socket.

Who this suits

This cooler suits builders who want a 360 mm AIO with integrated cable routing, VRM cooling and socket-specific mounting for current Intel and AMD desktop platforms. It is not for systems that lack space for a 360 mm radiator, for motherboards where the M.2_1 slot would be blocked by the pump block, or for users who require mounting hardware for sockets other than LGA1700, LGA1851 or AM5.

Highlights

Questions about this item

How can I confirm the pump is running correctly after installation?

The PWM-controlled pump operates at 12 Volts; verify its speed reading in the BIOS or monitoring software to ensure it is active.

What comes in the box and what must I purchase separately?

The cooler includes the radiator, three fans with integrated cable management, a VRM fan, and the Intel LGA1700/1851 contact frame; no separate mounting hardware is required for supported sockets.

Which version suits a Ryzen multi-die processor best?

The native 5 mm offset mounting is optimised for Ryzen chiplet designs, giving optimal hotspot coverage on AM5 platforms.
