ARCTIC Liquid Freezer III Pro - 420 processor cooler

Arctic Liquid Freezer III Pro 420 is a CPU cooler with broad compatibility. 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 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 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. Therefore, heat accumulation in the water cooling system slows down, and power and temperature peaks can be effectively managed for a longer period. Despite 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 provide 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 temperature of the voltage converters using PWM.

Intel and AMD CPU Cooler Offset Mounting: This moves 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 is ready for immediate use. Fan cables are integrated into the wiring sheath, 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.


Note: Some motherboards may be incompatible 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.
