DeepCool AK620 CPU Heatsink – Review

The heatsink is a very undervalued piece of computers. Without it, there is no control of the temperature of the CPU itself, without which the computer cannot do anything. CPUs have temperature controls so they turn off as soon as they get close to it.

This is why a heatsink is important. It is true that the security measures of the CPU itself prevent overheating. ^^but the CPU itself gets hot even from the most casual use possible. Namely, no CPU heatsink, you don't have a minimally functional computer.

CPUs come packaged with a dedicated heatsink from the manufacturer, usually tailored for own brand CPUs. But for those who want more from their cooler, especially to have more airflow with which to ensure that the CPU does not reach extreme temperatures or even be able to overclock it without suffering damage. This is why more advanced coolers like the DeepCool AK620 CPU cooler exist. They are generally much larger and more efficient at moving airflow, or making them passive to minimize noise, generally this is the case for office computers.

Oversized heatsinks are made for those who want to squeeze their CPU

It is at this end that we have the DeepCool AK620 CPU cooler. It is large and with several fans, so that the air flows as much as possible. We have done several tests and we already anticipate that we have loved it. Firstly for its value for money knowing that it is a heatsink that pulls to the domestic being equally high-end.

We thank DeepCool for giving us this product for review.

The DeepCool AK620 CPU cooler case. A simple design, and that invites you to look at what is inside it.

On the back we find the long list of features of the heatsink. They are the same ones that are on the official website and which we put below. They are set up for the curious to look at and share, but more than anything it will be the enthusiasts and the most dedicated who will stop to look at all the details put on the back.

When opening the box we find enough protective foam and the heatsink without being wrapped in plastic to protect it independently. Luckily, the protective foam itself is well fitted so that the heatsink is not damaged, unless there is a very strong and direct hit during transport.

When we take the heatsink out of the box, with the foam for its protection, we must do it very carefully and not take it out suddenly or break the box eagerly.

Included in the package is the mounting kit to install the cooler on different motherboards and sockets. They include the screws and the appropriate wrench to be able to tighten them correctly. We remember that it is imperative to use the screws and keys offered by the manufacturer to avoid damaging any component, be it the heatsink or the motherboard, and to ensure correct installation.

As well includes a small dose of thermal paste. It is always good to have even a little. The amount that is included is not enough in case at any time we have to remove the heatsink from the motherboard to do maintenance. But it is enough quantity for the initial installation.

This is the DeepCool AK620 CPU cooler, without a box and without a protective foam next to it. It is appreciated its sandwich design consisting of two heatsinks and two fans interspersed.

Not visible from the picture, but the fan on the end it can be both moved or disassembled and put it on the other side so that, instead of pushing air, it sucks it in. This is done because of its enormous size, on some motherboards it may collide with the RAM memories. It can be unpinned from the metal arms, raise it as necessary and rehook the metal arms to put the fan above the RAM memories. If it is not possible, we refer to the possibility of putting it on the other side, even if this reduces the cooling somewhat.

Seen from the side, its design is more appreciated by inserting a heatsink and a fan. The metal arms are an important part of the structure and are what ensure that they are fixed after installation.

From this side we can see one of the DeepCool AK620 CPU coolers. In a checkerboard pattern, scales are interspersed in different directions so that the hot air is not concentrated in one direction and is thus more dispersed to improve ventilation and air flow.

We also appreciate the six heat pipes which will cause heat to flow from the CPU to the heatsink, and from there to the fans. They have a quality finish and are very resistant. They comply with what is expected of a heatsink, if it is treated well, it will not spoil.

Pay attention to what we say that it is the dissipator that does not deteriorate. This is if it doesn't take hits and is well stabilized. We do not include the fans, since those have a limited useful life of between three and a half to five years of intensive use.

This is the top of the DeepCool AK620 CPU cooler. Here you can see a somewhat careful design, since right now it is very common for the internal components of a PC to be seen through sides with tempered glass or a plastic screen. This design helps to not “look ugly” in conjunction with current ARGB RAM memories.

At the bottom, apart from seeing the power connection cables for the fans, we see a protector for the surface that will absorb the heat from the CPU.

DeepCool AK620 heat dissipation tests

As we can say a lot from our experience, but what counts more are the results, we had to do some tests with our dedicated bench. The tests have been done with an overclocked AMD Ryzen 5 2600X CPU, on an open motherboard of a workstation, without being inside a box.

We understand that it is not a real representation of how the ventilation would be compared to if it is in a mounted box, since it is not usual or recommended for closed systems. But it is our way of having an accessible and open system to carry out the different performance tests of the components on our website without the handling of different hardware being a problem.

All the tests we've done have been with this same work team and has given us the following results in the following comparison. We have taken into account the ambient temperature, the test being carried out in an air-conditioned office in March. We've idled it for a few minutes, and then stress-tested the CPU to see the heat dissipation potential of the DeepCool AK620.

As you can see, we can say that the heat dissipation in idle is not among the best of the best. There are few other ventilation solutions that have had better results. But you have to understand that heatsinks with fans they are not at all vital for computers in idle or with minuscule workloads. That's what passive heatsinks are for, which allow heat to be dissipated without making any noise.

It has also not been the best heat sink at full load, since the temperature reaches 56 degrees. It is not a bad data, although more heatsinks manage to reduce the temperature in this use case. But we have noticed that it works especially well when it is in prime 95, since it stabilizes at 58 degrees. Until 56 degrees, the temperature rose very quickly, but it is at that point when it did not rise as much and stopped growing.

These are the most objective data we can have on the DeepCool AK620. As it stands, it's a cooler that offers great cooling value for its price. Above all you will notice if you use very CPU-intensive games and programs, and if you can stand the noise of the fans.


Mounting the DeepCool Heatsink

Although it is an experience that for us is almost routine, for many others the mounting of the heatsink is something out of the ordinary and that is only done when changing the CPU. Or in the most common use case, that we want a better heatsink than the stock one for an overclocked CPU or that the normal heatsink is deteriorating. The assembly process has been somewhat more complicated in the first instance than normal, but in general, much simpler.

First of all is its enormous size: the photos do not lie, it is that big. Very surely even if we don't use mini-ATX or micro-ATX sized cases, it is possible that our box does not give us enough space. It can also happen that due to the motherboard and its distribution, the heatsink collides with the RAM memories. In this case, one of the fans can be moved, even if it makes it have less cooling power.

But the assembly is a unique and exceptional step, not a routine one. And contrary to what we can make you think, the assembly has been easier than normal at the key moment of anchoring the heatsink to the socket.

In the majority of anchors of any heatsink, it is normal to find problems due to how delicate they are, since they have to be compatible with the majority of sockets from different manufacturers. This one has been surprisingly easy to put together. In the office it is normal to have to assemble and disassemble numerous CPUs and with them their heatsinks, and it is with this experience that we can affirm that this It has been one of the easiest heatsinks to mount.

Whether it's a professional who has to deal with dozens of CPUs in a week or a hobbyist who simply wants to upgrade their CPU, making heatsink mounting easier is always something to be thankful for. With this, in addition, it is achieved that there are less chances of error, be it a misguided force or a pressure in the wrong place that could damage the CPU or the motherboard. This minimizes the risk of damage due to mounting.

One of the components that has enchanted us the most is the screw with the same plastic spacer in one piece so that we can put the backplate below the motherboard. This is so that it comes out from the bottom, and we can tighten that screw by hand. Is a very ingenious solution to a problem that is presented to many users: change the CPU or the heatsink inside the box itself without disassembling the motherboard, which is when it is more cumbersome.

In the office we use an open test stand, and this simple screw with the separate one has made mounting much easier and safer. It is something so simple that it is hard for us to believe that it is not something more standardized, knowing that it will be useful whether we are those enthusiasts who change CPUs every significant change in performance in a generation, or if we work in equipment maintenance, that everything helps to more easily and safely handle equipment worth hundreds of euros, is significant.

One of the small cons that we have noticed is that managing the fans themselves to install it can mean some risk of friction and small bumps or pulls. It is necessary to remove the internal fan to be able to screw the heatsink correctly. It is imperative to do so, which highlights this inconvenience that we have encountered. When putting the central fan back, there is a risk that the fins collide with one of the heatsinks, and you have to handle it very carefully.

DeepCool designers have been aware that being a large heatsink both in height and width, there is the possibility that certain motherboards have the RAM next to the CPU and therefore the DeepCool AK620. The external fan can change its own height, and not disturb memories up to 59 millimeters. Then there is the possibility of changing the external fan side so that instead of pushing air, it will suck air, but it would not be as efficient.

Incompatible with Intel Alder Lake, but that's not a bad thing

At the end of last year, the first Intel Alder Lake CPUs began to hit the market. The 12th generation of Intel Core introduces a new socket, which is currently not supported by the DeepCool AK620 CPU cooler, or at least we don't see it listed on its official compatibility list. This is important, since many enthusiasts who would like to have a cooler like this, of such quality and versatility, will most likely also want to have an Intel Core Alder Lake CPU.

But these CPUs use the new LGA 1700 socket. It has happened that with other liquid cooling, a mounting kit is sent to users so that said liquid cooling does not spoil. However, we do not see this being the case with the DeepCool AK620 CPU cooler as of today. Does this mean that we do not recommend it because it is not suitable for newer CPUs? Well, it is not like that, since the change of CPU requires a very substantial change that implies a motherboard and even new RAM and it is only for the most dedicated enthusiast.

Many of us still use CPUs from several years ago that still work perfectly. Whether it's because the stock heatsink is starting to fail or we want to test our feet with overclocking, a move to a better heatsink is necessary. It is in that use case that we are going to recommend the DeepCool AK620 CPU cooler the most.

Now, Deepcool can easily announce that it will continue to provide LGA 1700 adaptation kits for Alder Lake as well as the future Raptor Lake and send kits to adapt it to the new socket. In that case, we could recommend it even more for its low price and extremely efficient cooling and its ease of assembly.

  • Very good price for its benefits.
  • good performance.
  • Installation is particularly easy.
  • Your own size. It is very likely that in smaller boxes such as the Mini-AtX or Micro-ATX it will not fit. But they would not be computers that require a processor that requires a heatsink of this size.
  • It is not compatible with the LGA 1700 socket released with the Intel Alder Lake.
  • You may bump into some of the larger memories.
  • At idle, the heat dissipation is not that great.

DeepCool AK620 CPU cooler enjoys great value for money based on its heat dissipation. And it is easy to assemble.
