Arctic Liquid Freezer II 420 CPU Liquid Cooler :
Overview :
COMPATIBILITY WITH LGA1700
Arctic Liquid Freezer II 420 With the LGA 1700 mounting kit, the entire Liquid Freezer II Series is compatible with Intel’s new Alder Lake processors. Even if the socket and heat-spreader are larger compared to the predecessor, the CPU surface has been reduced and remains centered. The Arctic Liquid Freezer II 420 completely covers this area. ARCTIC will provide the required mounting kit free of charge to customers who submit proof of purchase of a processor with an LGA 1700 socket.
All Liquid Freezer II models ordered from the webshop already include the LGA1700 mounting kit.
«SECOND GENERATION PRICE-PERFORMANCE-CHAMP»
(ALLROUND-PC.COM)
The Arctic Liquid Freezer II 420 has been tested numerous times by independent reviewers and has been awarded for its performance, price and quiet operation. It exceeds all expectations and has set new standards in the field of compact water cooling. The Liquid Freezer II was also awarded the “European Hardware Award 2020” for the best liquid cooler in the 240 variant.
OUTSTANDING PERFORMANCE
Arctic Liquid Freezer II 420 all-in-one cooling handles the entire cooling requirements – even of the most powerful processors from Intel® and AMD®. It performs effortlessly with over 200 W of heat to be dissipated, which is why your CPU can be kept cool even in extreme overclocking. When it comes to competitive products from leading cooler manufacturers, the Liquid Freezer II leaves them behind in terms of both performance and noise level.
EFFICIENT, IN-HOUSE DEVELOPED PUMP
Unlike many of our competitors, we went to great lengths to develop the water pump. The result is greatly reduced humming and higher efficiency. Like the other components, the pump is also PWM controlled. This leads to a significantly lower noise level at low and typical loads, but also to much lower power consumption, with a maximum of of 0.8 W at no load, 2.3 W under typical load and a maximum of 4.3 W under full load for the entire AiO.
PREMIUM CLASS RADIATOR
Unlike most other all-in-one liquid cooling manufacturers, we rely on 38 mm thick radiators with a high fin density. This means that a larger amount of water can be used in the circuit, and the cooling surface can be significantly increased.
Water has a much higher heat capacity than aluminum or copper. This leads to a slower and up to 5 ° C lower temperature increase in the temporary turbo mode of modern CPUs.
SMOOTH VRM FAN
Small fans have a reputation for being particularly loud and not very durable. However, we have developed a quiet and durable diagonal fan especially for the Liquid Freezer II and are 100% convinced that this 40 mm fan is just as durable as our other case fans. In the unlikely event that it should fail, our customer service team will send you a replacement free of charge and easily, without a need to replace the entire unit.
The fan is PWM-controlled and can cool your voltage transformers and the base area almost inaudibly by up to 15 ° C. This is especially effective in overclocking scenarios, inadequate VRM cooling or in housings with poor airflow, thus permitting continuously high loads. If sufficient VRM cooling is available, it can be switched off at will.
HIGH QUALITY HOSES WITH INTEGRATED CABLE MANAGEMENT
The fiber-reinforced, long EPDM tubing of the Liquid Freezer II enables installation even in large cases and effectively prevents the cooling liquid from evaporating, so that you do not have to worry about refilling the compact water cooling system.
It also hides the cables of your radiator fans thanks to sophisticated cable management. So you only have to connect a plug to the mainboard, saving valuable time during installation. In the end, you won’t need to hide any more cables and your view is reduced to just the essentials.
FAN OPTIMIZED ON STATIC PRESSURE
The popular P-fans are already installed on the compact water cooling from the factory, lending the following advantages:
| • High static pressure for improved cooling performance | 2,2 mm H2O |
| • Extended speed range | 200 – 1800 RPM |
| • Lower power consumption | 0,08A |
| • Less vibration | reduced by 95% |
| • Improved lifespan | 10 year guarantee |
| • High quality fluid dynamic bearing | |
| • PWM for synchronous pump/fan control |
THE RIGHT CONFIGURATION FOR EVERYONE
Thanks to its long hoses, availability in 5 different sizes and different lignting options the Liquid Freezer II Series is versatile. It is highly compatible and can be used effectively, from small form factor PCs (be aware of the radiator thickness!) to big towers.
