ARCTIC Liquid Freezer III 420 – All-in-one Liquid CPU Cooler in Black – 420mm
Outstanding cooling performance through liquid cooling. ARCTIC’s Premium Liquid Freezer range offers impressively high performance at moderate prices without the complexity of conventional CPU water coolers. Completely maintenance-free, the all-in-one cooler with various models for smaller and larger cases covers all the most important current CPU sockets.
Ready Out-of-the-Box – Easy Installation
The 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 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, VRM and radiator fans can therefore be easily controlled via a single PWM setting.
Native AMD Offset Mounting
For several generations, AMD has been using a multi-die chiplet design for its Ryzen desktop processors. Unlike Intel CPUs, the hotspot on these processors is not located centrally under the IHS (Integrated Heat Spreader), but is slightly offset. The AMD mounting solution therefore has a 5 mm offset in order to achieve optimum heat dissipation.
Improved Radiator Design
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.
High Static Pressure
ARCTIC relies on the well-proven P fans, which have already received several awards for their outstanding performance. The P series is particularly suitable for use on heat sinks and radiators with a high fin density. Thanks to their high static pressure, they achieve significantly better results compared to fans designed for high air circulation.
Limited Compatibility with Few Motherboards
Some motherboards are incompatible with the Liquid Freezer III due to oversized SSD coolers in the M.2_1 slot. We provide a suitable M.2 cooler free of charge for affected motherboards.
Wide Range of Variants
The Liquid Freezer III offers outstanding cooling performance in four different sizes and three variants. While the Black version is completely black, the A-RGB versions are available in black or white and have digitally addressable lighting for the pump head and radiator fans. With radiator sizes of 240, 360, 280 and 420, the Liquid Freezer III offers the ideal combination of performance, technology and design for everyone!
