Plastic wrapping is a common way to keep products safe during shipment. This helps prevent any unwanted substances from damaging the item.

You will see that the radiator and pump are layered with a cardboard box. With that, it protects the product from unnecessary movements.

Within the package, you will notice a small white box. It holds all the important mounting pieces needed for the cold plate. There are adhesive washers too to help mount the item.

There have been cases where the product won’t fit the case you have. Therefore, you can contact Arctic to check if the cooler will fit the case and processor you have.

Arctic Liquid Freezer II 420 AIO Cooler Review – Design and Functionality

Let’s now discuss the design and functions in our Arctic Liquid Freezer II 420 AIO Cooler review. The Arctic Liquid Freezer II 420 AIO Cooler is made up of many intricate parts.

The radiator scores a black colour with its fans already attached. Its job is to manage the circulation of the airflow and keep the operation cool. As a result, it allows your PC to run at a higher performance rate.

With the radiator connected to the different parts of the cooler, it maintains the liquid’s temperature within the system.

Going over the tubes, they are black and braided neatly which are attached to both the radiator and pump. With the fittings connected, it provides easier maneuvering around the case.

Additionally, with the tube design, it prevents leakage of any kind as well as evaporation. With this type of cable, it grants better cable management.

For Arctic, it is always important to consider the cable management of the user. With this into consideration, Arctic opted for a better way to efficiently manage the cables, and we see that here.

On to the next step, we’ll talk about an unlikely duo. Arctic has redesigned its pump and cold plate to better function in a more simple way. By combining both and putting them in the same component, this makes it more efficient.

When understanding our product, we realise that these two play key roles in maintaining a proper, orderly operation. How does this happen?

Our pump acts as the distributor that moves the cooled liquid around the device, and our cold plate uses this to cool down the processor. These two work together to get the job done.

Not only the cold plate and the pump need to work together but also the VRM Fan which is attached to both.

The goal, which the VRM Fan has to do, is to guide the air currents to a single point. Another one is to focus the cooling on one target, which is the processor.

With the VRM Fan installed, this helps manage the heat levels within the processor and the liquid. It is the medium for the pump and the cold plate.

All things considered, our Arctic Liquid Freezer II 420 AIO Cooler is a next generational product designed to fit the millennial gamers of this age and the next.

Key Features of the Arctic Liquid Freezer II 420 AIO Cooler

Other than its architecture, we move on to the features this product has in our Arctic Liquid Freezer II 420 AIO Cooler review.

Efficient and Reliable

Power is good, but being efficient and reliable can be more challenging. Efficiency and reliability come hand in hand, and we see that here in the Arctic Liquid Freezer II 420 AIO Cooler.

Arctic has taken this challenge directly and faced the problem with their combined units. Having both the pump and cold plate in the same area allows more room for cooling and distribution.

Designing a pump and cold plate that work together well can bring favourable outcomes. As the two work together, this makes the device more consistent and versatile.

With this, the outcome greatly increases temperature management and as an addition, reduces noise levels. Only proving the point that Arctic has developed efficient and reliable products.

Performance Rates

With the Arctic Liquid Freezer II 420 AIO Cooler being efficient and reliable, this, in turn, leads to better performance rates. The product offers better operations for systems that use demanding applications.

Due to how it was made, our Arctic Liquid Freezer II 420 AIO Cooler can take on heavy applications while being consistent and silent.

Bigger Better

Our Arctic Liquid Freezer II 420 AIO Cooler is the largest in the series. With three 140 millimetre fans, it expands the cooling region all around the system.

The more cooled liquid can be stored and distributed around the system during operations with a bigger and thicker radiator. As a result, it boosts cooling performances.

As one can see, Arctic and their line of Liquid Freezers, are one of the best coolers in the market to date. With ever-changing sizes to fit any PC system, you are sure to find the one you need.

AIO Dimensions

The radiator is set to be 458 by 138 and 38 millimetres. Although it may seem to be very long, its size helps extend the cooling operation inside.

Its pumps without the tubes are 98 by 78 and 53 millimetres. Its tube diameter outside is 12,4 millimetres and inside is 6,0 millimetres.

For the tube length, it extends to a full 450 millimetres. Its weight in total would be 1977 grams. This includes the radiator, pump, fan and tubes.


Looking at the cold plate, we find that it is made up of copper, which is a very common material used together with Micro-Skived-Fins. It comes with an MX-4 thermal paste which needs to be applied.

Power Consumption

Regarding the pump speed, it can go up from 800 to 2000 rotations per minute. This is strong but maybe power consuming. Power consumption goes around 0,5W to 2,7W.


The VRM Fan is only 40 millimetres in size which can go up to 1000 to 3000 rotations per minute. It’s strong indeed as it increases with speed. With that, it keeps your system cool for longer periods.

Going now to the fans attached to the radiator, they are three Arctic P14s and are sized at 140 millimetres. This is bigger than the Arctic P12, which is only 120 millimetres in size.

These types of fans can run up to 200 to 1700 rotations per minute, keeping your system relieved from heat.

Our Arctic P14 fans have a fluid dynamic bearing which helps reduce noise levels to 0,3 sone. Airflow within is kept constant with a 72,8 cubic feet per minute. This indicates that airflow would flow faster inside.


Our Arctic Liquid Freezer II 420 AIO Cooler is versatile with some of the most common processors.

For Intel processors, it fits well with 1200, 2011-3*, 2066*, 115X and Square ILM. For AMD, you only have AM3(+) and AM4.

Its warranty would be around 2 years from when you purchased the product. Therefore, if anything were to happen within the set amount of time, feel free to contact them or visit their store.

Alright, we now have finished talking about all the necessary information, let’s go and see how well it performs.

Hands-on with the Arctic Liquid Freezer II 420 AIO Cooler

Alright, moving away from the technical details, we now head on to see if the product is worth your money in our Arctic Liquid Freezer II 420 AIO Cooler review.

During the setup, we were surprised to find it to be incredibly quiet. It kept noise levels low all throughout the tests and we found it to actually be quieter than 360mm coolers that we have tested from other brands.

Moving forward, we wanted to see how well the product can keep the temperatures running nice and cool in our test system. With the coolers large size and thermal design, we noticed the temperatures never exceeded 47°C. We boosted the processor’s power output and ran it under load and found it to only reach 61°C.

As with their previous products, Arctic Cooling has stayed true to what they advertise when it comes to cooling performance. Our Arctic Liquid Freezer II 420 AIO Cooler stayed efficient, reliable and silent.

We can easily say that the Arctic Liquid Freezer II 420 AIO Cooler is one of their best products, provided that you have space in your case to install it.
