The delivery of the Arctic Liquid Freezer II 420 AIO …

In the usual Arctic Design in blue/white we accept the new Liquid Freezer II 420. On the front side we see an image of the water cooling system and on the left side a reference to the two-year warranty and a QR code that leads to the online product page.

The backside is printed with some pictures to illustrate the most important features of the water cooling system. This includes the integrated fan for cooling the motherboard voltage regulators. There is also a link to the support page of the watercooling, which provides the installation manual in 8 languages. The comparison chart with the Liquid Freezer II 240 should give you a foretaste of the increased cooling performance.

On the bottom side we can see beside the product codes also that this model is already the third revision of the Liquid Freezer II series.

If you open the lid, the solidly packed CPU cooler in cardboard and plastic foil appears. There is no need to worry about transport damage.

Here we have the big 420mm radiator with the three pre-assembled 140mm fans and the already known CPU cooler.

The following accessories are included.
– the holding brackets for the cooling block
– the new AMD mounting kit
– the backplate for Intel systems
– Screws and washers for final assembly
