Phanteks is a relatively new brand in the cooler market, and this Heatsink we see here is the first one they create.
Among its technologies, the use of heat pipes stands out, which are copper tubes that have a liquid inside, which facilitates heat dissipation, and this time they are 8mm in diameter, the standard being 6mm.
Apart from this, two exclusive features were included, such as the PATS (Physical Anti-Oxidant Thermal Shield), which deflects the heat generated by other external sources, such as rams, northbridge, and southbridge, to increase its dissipation power. On the other hand, we have the CPSC Technology (Cold Plasma Spraying Coating), which implies more thermally efficient welding, between heat pipes and aluminum fins, which facilitates faster heat dissipation.
The Heatsink comes in a medium-sized box, with a weight that exceeds one kilogram. You can see that Phanteks promotes the different colors of this cooler, which are red, blue, black, white, and orange, also on the sides are the specifications. The Heatsink is quite large in question.
In fact, due to its design, likely, it does not enter many cabinets due to bumping into the side or it may have problems with the memory sticks due to its width. Aluminum fins are nickel-plated in some specific color, and this is a detail that very few brands have and that in the end, in something as colorful as this, it is greatly appreciated.
So it is that the Phanteks deserves to be displayed in a cabinet that has a side view of the mounting hardware.

Ultimate Buyers Guide
It may seem like purchasing a CPU cooler for your build is simple and in most cases it is.
However, if you want to get more performance out of your build, you’ll need to invest in a third-party CPU cooler and ditch the stock one that came with the processor.
What Does a CPU Cooler Do?
Modern processors come with a temperature sensor built-in that ensures the processor never overheats.
Thermal throttling is a genuine issue for a number of different users.
Power users who like to render 3-D models, architects who want to modify huge files, and even gamers who want to get the best performance and frame rate out of their build.
A CPU cooler tries to move the heat away from the competence and exhaust them outside the chassis.
This ensures the temperature remains optimal and your performance never gets throttled.
The basic functionality of a CPU cooler is simple, heat pipes that are made from copper are filled with a liquid that vaporizes when heated.
The vapor then travels to where the cooler where it gets goes down and condenses.
The whole process releases the heat that was captured by the liquid.
Mostly a large area of cooling fins is used along with a fan to further enhance the cooling effect.
Do You Need a Third-Party CPU Cooler?
While stock CPU coolers that ship with the processor are good enough for most cases, they are not equipped to handle extreme performance.
A third-party CPU cooler is definitely needed to push the processor to its boundaries.
Types of CPU Coolers
There are 3 major types of CPU coolers but they can be further categorized.
- Air Coolers
- Water Coolers
- AIO/Liquid Coolers
We will discuss the benefits of each of them and help you decide what type of CPU cooler is best for your build.
Air CPU Coolers
As the name implies, the air-based CPU coolers rely on good old-fashioned air to cool down your processor.
They use copper heat pipes as well as aluminum fins to keep the temperature lower. Usually, there is a fan but you can even find air-based coolers that are completely passive and noiseless.
Air CPU coolers are super simple to install and don’t require anything extra.
There are not many drawbacks of using an air CPU cooler, however, if you are an extreme overclock enthusiast, they may not be sufficient enough for you.
But for normal users with some heavy loads or gaming needs, these will do perfectly fine.
Water CPU Coolers
There was a time when the water CPU coolers were all in the rage.
Not only they looked amazing but they also provided good quality cooling experiences.
However, these days they are not so common.
So it is very difficult to find them in normal builds these days.
AIO CPU Coolers
All-in-one CPU coolers combine the benefits of liquid CPU coolers and the ease of installation of air CPU coolers into one package.
You’ll be getting the cooling power of water but you will need to put anything inside it yourself.
As they are closed loops, they won’t need any maintenance and have a very small chance of leaking if properly handled.
All-in-one CPU coolers provide some of the best performance there is and they can look downright gorgeous in a proper build.
If you an enthusiast who wants to overclock their processor, this is the way to go.
How Did the Test?
All of the CPU coolers were tested on this same system with the same specs.
The use of an Intel i7 8750 Coffee Lake processor, 8 GB of RAM, 700 W power supply, Nvidia 970 GPU, and Cooler Master MasterCase 5 mid-tower chassis.
We also tested the CPU coolers in a temperature-regulated room set at 26°.
It took a little while to completely test them, especially because we ran several benchmarks as well as ran organic tests on them.
We rendered a 15-minute 4K video and played 20 minutes of Far Cry 5 on the system.
It was a fairly simple but time-consuming process to test all these CPU coolers.
We hope that the best CPU coolers of the 2021 buyers guide will help you make a conscious decision that will not only keep your CPU cooler but also provide you with greater performance even in the summers.
We tried including top-of-the-line CPU coolers in all categories but of course, be made have missed some that are equally remarkable.
Feel free to inform us if we have missed an epic CPU cooler that deserves to be on the list.
