Introduction to the characteristics of the Arctic Freezer 50

When we talk about heatsinks, size matters, either because we need a compact one for one of those modern computers with low cubic capacity, or because we want the best dissipation for our mid-range or high-end processor. In the latter case, the bigger the better, since the more heatsink surface and more fans, more cooling, but also achieving the intermediate point, cooling and low noise, can be somewhat complicated with dual fan heatsink blocks such as Case of the Arctic Freezer 50 to which we dedicate this review.

Arctic, as one of the reference brands, knows that this is so and in his Freeza 60 , one of its largest models, combines two fans in a “Push-Pull” configuration, the main one being 148 mm in diameter, which is a guarantee of low revs and high flow of air movement.

Arctic Freezer Technical Specifications 50

This model is not new in its main design, but there are important adjustments since the contact base of a Threadripper is not the same than a normal Ryzen or a 9th or 10th generation Intel. The design remains the same, in a double vertical aluminum tower configuration, with room for two fans, one of 148 mm and another of 130 mm diameter.

The two towers are designed in aluminum with the sheets further apart than what we usually see, a few additional tenths of a millimeter, to maximize the air flow between them, but at the same time, in such a large configuration, maintaining an impressive dissipation and exchange surface throughout the set. The sheets are also thicker than usual, made of 0.4mm thick aluminum strip.

The heatsink itself is a marvel in terms of dimensions. Weight 1160 grams, with the two fans, and has dimensions of 148 mm long, 150 mm wide and 166 mm high, the same as the version for Threadripper processors. This configuration offers more than 300 w cooling capacity.

The fan configuration is of the “Push-pull” type, the smallest fan, of 130 mm in diameter, which is what we can see outside, introduces air into the first dissipation element while the largest fan, of 148 mm pulls that cool air out and blows it out through the second set of laminated block.

One of the big problems that we encounter this heatsink in our tests on the variant for Threadripper processors is that it did not support high memory. In the processors for which this variant is designed, we will not have such a problem, but we will still have a memory restriction of some 50 mm high.

The towers are powered by 6 nickel-plated copper heatpipes with a size of 6mm in diameter, in the TR model, for Threadripper processors were 8 of the same size, and direct contact with the processor. With the six in direct contact with the processor we cover the “heatspreader” of any processor that is compatible with this model.

The copper from the manufacture of these heatsinks increases the cooling capacity , condensing and evaporating the liquid inside the heatpipe, while nickel plating offers the heatpipes a more durable surface, resistant to corrosion and that will not take on the dark color typical of the natural and superficial oxidation of copper.

Fans

The great advantage of these large dual tower heatsinks is that the efficiency of using two fans is much higher than others with larger bodies in a single block, here the air inlet and outlet configurations become much more efficient which allows Arctic to develop an efficient heatsink that produces little noise but also able to calm these processors when they are in stress with all their cores at high levels of use.

Arctic uses two different size fans, which on the Paper does not seem like a great idea, but it is clear that it also prevailed in the design to achieve a more modern look and better finishes through a plastic cover where also two ARGB lighting lines are added finished with a logo with this same lighting capacity.

To compensate for the difference in sizes, Arctic has used two fans with different capacities and blade configurations. . That of 120 mm develops frequency between 300 and the 1800 rpm and that of 148 mm between 300 and the 1700 rpm, both with bearings immersed in oil. Both are powered by PWM and at rest they are two authentic tombs. According to the manufacturer it has a maximum combined noise of 40 dBA , something that we can test later.

Mounting

The fan of 148 mm acts as the main and it is the one that we must extract in order to mount the heatsink on the socket. The mount includes two brackets that go to the socket and then a two-point spring mount for the contact block. It is simple to assemble and we will have the adequate wiring for the connections of both motors and independent for the ARGB system that it includes. It is compatible with any modern processor of the middle and high ranges of Intel and AMD except the Threadripper, which we have already been saying have their own customized version.

It takes little more than five minutes to mount the heatsink and it has no loss, it also includes Arctic MX4 thermal paste for a single application, something that I personally see somewhat scarce since it is always good to give some maintenance to the thermal paste as the months go by and this small amount will force us to buy more when the heatsink has a cost of 60 Euros.

Noise, temperature and resu ltados

When you mount this heatsink on a mid-range processor, you immediately realize that you have hit the mark. When you see him at rest, without overclocking, yes, to 200 rpm, or less, you realize you have chosen the heatsink you wanted, even if you weren’t really looking for a terribly quiet model.

On the other hand, their 120 Long cost euros, are like to be clear about what we are looking for and if we are looking for noise management then we have fully succeeded in our choice and the 120 Euros will know us as a perfect investment. Now, we will have to live with its impressive size, which as you can see in our assembly tests completely fill our ITX box, yes, and this is our opinion, with impressive finishes.

Analysis and conclusion

Of this model we already tested the version based on AMD’s Threadripper processors, much hotter processors, with TDP above 200 w which makes them quite difficult to handle even for large heatsinks like this one.

The Freeza 50 this intended for processors with less consumption, maximum 130 – 166 w, but it is designed in the same way as its brother for AMD Threadripper models so the result is a much more abundant heatsink, with a silent behavior and that maintains really good temperature levels. A marvel.
