Arctic Liquid Freezer III – 420 is a wide compatibility CPU cooler Compatible with Intel Alder Lake and Raptor Lake LGA1700 processors and the new socket LGA1851, as well as AMD AM5 and AM4

Features:

Liquid Freezer III is multi-compatible with most common Intel and AMD sockets Intel will release the new Arrow Lake processors on the LGA1851 socket in the future ARCTIC customers don’t need to worry that the new CPUs will also require new coolers The manufacturer guarantees full compatibility: Liquid Freezer III can be used with the new LGA1851 socket from Intel without limitation

LGA1851/LGA1700 contact frame: Intel’s Independent Loading Mechanism (ILM) deforms the CPU by pressing it into the socket at two points with over 40 kg This causes pressure in the PCB, the DIE and the solder layer between the DIE and IHS (Integrated Heat Spreader) With high thermal load, this can lead to long-term problems The mounting frame from ARCTIC does not deform the CPU, reduces the mechanical load on the CPU massively, is quick and easy to install and allows the cooler to be screwed onto the CPU’s backplate As a result, mechanical stress on the mainboard and CPU is minimised, cooling performance remains consistent and installation is quick and uncomplicated

In independent tests, the Liquid Freezer III clearly stands out from the competition in all price categories, particularly due to its outstanding performance In noise normalised tests, the Liquid Freezer III shows its true strength, outperforming many competitors with its quiet yet powerful operation Excellent results of long-term testing allow us to provide a 6-year manufacturer’s warranty

The cooling surface of the 38 mm thick radiator has been extended by 23 % by increasing the fin stack This not only enables improved heat dissipation, but also a larger liquid volume Consequently, the heat build-up in the water cooling system is slowed down and power and temperature peaks can be effectively managed over a longer period of time

The Liquid Freezer III is equipped with a specially developed PWM-controlled water pump, which has been further optimised in terms of both performance and noise Thanks to the improved coldplate with an extended fin surface and optimised water pipes, the Liquid Freezer III increases its performance while maintaining quiet operation

The voltage converters of motherboards often work at their maximum temperature in combination with power-hungry CPUs To compensate the lack of airflow from a tower cooler, the Liquid Freezer III works with a revised VRM fan The 60 mm PWM-controlled fan enables almost silent cooling of the socket area when VRM cooling is insufficient, in cases with poor airflow or especially in overclocking scenarios This enables a continuously higher load and a longer service life for the voltage converters

Two connection cables provide two control options: Like the Liquid Freezer II, this allows the entire unit to be controlled via a single connection, whereby the speed of the radiator fans is output The pump, VRM and radiator fans can therefore be easily controlled via a single PWM setting Separate regulation: By using the splitter cable with three separate connections, the pump, VRM fan and radiator fan can be controlled independently of each other This allows, for example, the speed of the VRM fan to be controlled independently of the CPU and to be adjusted analogue to the temperature of the voltage converters via PWM

Note: Some motherboards are incompatible with the Liquid Freezer III due to oversized SSD coolers in the M2_1 slot You can check compatibility here: https://supportarcticde/lf3-compatibility
