ARCTIC Liquid Freezer III Pro - 420 CPU Cooler

The Arctic Liquid Freezer III Pro 420 is a widely compatible CPU cooler. It is 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 is compatible with most common Intel and AMD sockets. New P14 Pro fans ensure higher performance at any speed. The P14 Pro operates more quietly and 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. Increasing the cooling surface improves heat dissipation and also increases the liquid volume. Water has a much higher thermal capacity than aluminum or copper. Therefore, heat accumulation in the water 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 a longer CPU lifespan and better heat dissipation.

Two connection 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. This allows, for example, the VRM fan speed to be controlled independently of the CPU and adjusted analogously 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 temperature of the voltage regulator and ensures stable operation.

The Liquid Freezer III 420 Pro is ready for immediate use; the fan cables are integrated into the cable sheath, so only one cable needs to be connected to the motherboard. Together with the included MX-6 thermal paste, you have everything you need for quick and easy installation.


Note: Some motherboards may be incompatible with the Liquid Freezer III due to oversized M.2_1 slot SSD coolers. You can check compatibility here: https://support.arctic.de/lf3-compatibility.
