ARCTIC Liquid Freezer III Pro - 420 A-RGB CPU Cooler

Arctic Liquid Freezer III Pro 420 A-RGB is a wide compatibility CPU cooler with A-RGB lighting. Compatible with Intel Alder Lake and Raptor Lake LGA1700 processors and the new LGA1851 socket, as well as 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 higher performance at any speed. The P14 Pro A-RGB operates quieter and more powerfully at low speeds, and under load, it has a larger 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, as is the increased fluid volume. Water has a much higher thermal capacity than aluminum or copper. Therefore, heat accumulation in the liquid cooling system slows down, and power and temperature peaks can be effectively managed for a longer period. 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 connecting cables offer two control options: the entire unit can be controlled via a single connection, meaning the pump, VRM, and fans can be easily managed with one PWM setting. Another option: using a splitter, the pump, VRM, and fans can be controlled independently of each other. This allows, for example, the VRM fan speed to be controlled independently of the CPU and regulated analogously according to the voltage converter temperature using PWM.

Intel and AMD CPU Cooler Offset Mounting: Shifts the cold plate to the hottest spot of the CPU for more efficient heat transfer.

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

The Liquid Freezer III 420 Pro A-RGB is ready for immediate use; fan cables are integrated into the cable sleeving, so only one cable needs to be connected to the motherboard. Along 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 multicolored 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 be incompatible with the Liquid Freezer III due to oversized SSD heatsinks in the M.2_1 slot. You can check compatibility here: https://support.arctic.de/lf3-compatibility.
