ARCTIC Liquid Freezer III Pro - 420 A-RGB processor cooler

The Arctic Liquid Freezer III Pro 420 A-RGB is a wide-compatibility CPU cooler with A-RGB lighting. It is compatible with Intel Alder Lake and Raptor Lake LGA1700 processors, the new LGA1851 socket, and AMD AM5 and AM4.


Features:
The Liquid Freezer III Pro A-RGB is compatible with most common Intel and AMD sockets. New P14 Pro A-RGB fans ensure greater performance at any speed. The P14 Pro A-RGB operates more quietly and powerfully at low speeds, and under load, it has a greater performance reserve to provide maximum cooling.

The premium class radiator is 38 mm thick with a high fin density. By increasing the cooling surface, heat dissipation is improved, and the liquid volume is also increased. Water has a much higher thermal capacity than aluminum or copper. This slows down heat accumulation in the liquid cooling system, allowing power and temperature peaks to be effectively managed for longer periods. With increased performance, operation remains quiet. Please note that the Liquid Freezer requires at least 63 mm of clearance for installation.

Intel contact frame: Optimized contact pressure distribution ensures longer CPU lifespan and better heat dissipation.

Two connection cables provide two control options: The entire unit, including the pump, VRM, and fans, can be easily controlled via a single connection with one PWM setting. Alternatively, using a splitter, the pump, VRM, and fans can be controlled independently. This allows, for example, the VRM fan speed to be controlled independently of the CPU and regulated analogously according to the temperature of the voltage converters using PWM.

Intel and AMD CPU cooler offset mounting: Shifts the cooling plate to the hottest spot on the CPU for more efficient heat transfer.

Integrated VRM fan. The PWM-controlled fan reduces the temperature of the voltage regulator and ensures stable operation.

The Liquid Freezer III 420 Pro A-RGB is ready for immediate use, with fan cables integrated into a single braided sleeve, meaning only one cable needs to be connected to the motherboard. Together with the included MX-6 thermal paste, you have everything needed for quick and easy installation.

New ARCTIC A-RGB fans are used in this model, allowing for perfectly synchronized multi-color lighting effects. A-RGB lighting capabilities are more advanced than RGB, enabling more light and color effects simultaneously to create a unique look for your system.


Note: Some motherboards may not be compatible with the Liquid Freezer III due to oversized SSD coolers in the M.2_1 slot. You can check compatibility here: https://support.arctic.de/lf3-compatibility.
