ARCTIC Liquid Freezer III 420 is a powerful liquid cooling system designed to provide excellent thermal performance in high-performance computers. Featuring a massive 420mm radiator and three oversized air fans, this liquid cooling system (LCS) is ideal for gaming systems and workstations with Core i9/Ryzen 9 processors and extremely high thermal loads. At the same time, due to its size, it will not fit in every Midi Tower case, so the manufacturer recommends checking the compatibility of the components in advance.
The system pump is equipped with an improved pump, which is characterized by a high level of reliability and low noise level. The special design of the pump block ensures optimal distribution of coolant and efficient heat dissipation. The pump operates quietly thanks to the use of quiet, reliable and efficient hydrodynamic bearings. The same bearings are used in air coolers. An additional feature of this model is an additional cooling fan for the VRM area and near the motherboard socket space, which provides additional system stability and prevents overheating of critical components. The fans support PWM speed control over a wide range from 200 to 1700 rpm. Simplicity and ease of installation provide a solid set of mounts for the most current processor sockets, including Intel LGA 1700 and AMD AM5.

ARCTIC Liquid Freezer III 420 - Multi Compatible All-in-One CPU Water Cooler ACFRE00137A
Multi Compatible All-in-One CPU Water Cooler
Ready Out-of-the-Box - Easy Installation... moreThe Liquid Freezer III is ready for immediate use thanks to its pre-installed radiator fans in push configuration. The fan cables are integrated into the jacket of the hoses so that only one cable needs to be connected to the motherboard. With the MX-6 thermal compound included in delivery you have everything you need for quick and easy installation.
Future-Proof Compatibility
The Liquid Freezer III is multi-compatible with 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. We guarantee full compatibility. All Liquid Freezer III can be used with the new LGA1851 socket from Intel without limitation.
Silent and Powerful VRM Fan
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.
Contact Frame for Intel LGA1700 and LGA1851
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 patent-pending 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.
Optimised In-House Developed Water Pump
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.
Complete Control or Simple Control
Two connection cables - two control options:
- 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

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. All-in-One: 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,
