Quite, Performing yet Expensive!
  • Comes with a patented Physical Antioxidant Thermal Shield (P.A.T.S.).
  • Good product reviews.
  • Long life.
  • Large Heatsink.
  • Lightweight.

Check Price on Amazon

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, in order 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 the 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, it is likely that 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.

The product is difficult to install.

First, you have to adjust a screw in the middle that will support, but for this, we will need patience and a long screwdriver, preferably magnetized, since it is difficult that the screw does not come out when we try to place it.

This can be a bit of a turn off if you are really a fan of quick installations as with other products.

The Phanteks has a simply impeccable finish and very consistent with its surname “Premium Edition”.

The first is its high cost, but if you want to “transform” the system due to RGB backlighting, you can hardly find any alternatives unless you buy a standard S.J.O., separately RGB fans, which together will lead to the same price.

The second important point is that the fans and the pump are connected exclusively to the standard control unit with their own control program, so if the case, motherboard, and video card have RGB lighting, it will be problematic to synchronize their work with the backlight of the S.J.O.

So, this product does carry a high price, but its efficient components and smart cooling system can make it all worth it. This is highly recommended for gamers who want to take their gaming modes to another level and remains one of the best water cooler for PC.

Castle 360EX RGB is superior in power and silence to air super coolers and low-cost air-conditioning systems, although it does not reach the level of top solutions on the market. It all depends, probably, on the performance of the pump and the caliber of the hoses installed here.

The presence of an L.E.D. strip and RGB backlight in the upper part of the water block is certainly good, but it is unlikely to be a decisive factor in favor of choosing this C.B.O. First of all, because you can take the technically identical 360EX, without an RGB prefix (only a red backlight diode is built in there), and save money.

If RGB is needed, then the implementation of the backlight can hardly be called outstanding. It is a top-rated product that also remains quite popular among other gamers.

In fact, this product remains standard in the market for gaming PC because, for some time, it has been able to perform really well.

Of the shortcomings noticed during use by customers, it is worth noting the hose inputs that are not located on the side, which do not allow you to turn the system the other way around and can conflict with high memory or other elements of the motherboard.

This is a similar factor that was experienced by customers of the advanced version of this product – the Captain 360EX RGB.

The manufacturer’s name stands out in convincing customers to purchase this product for an excellent gaming experience. It is ideal for users who like to use the most robust and durable components in terms of computer hardware.


  • Efficient cooling system.
  • Customizable logo.
  • Compatibility with all modules of RAM.
  • Easy installation of the product.


  • Expensive.

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.

Buyer's guide to the best cpu cooler

What Does a CPU Cooler Do?

Modern processors come with a temperature sensor built-in that ensures the processor never overheats.

However, if the temperature goes above a certain threshold, the processor will throttle the performance until the temperature normalizes again.

This means you’ll get less performance out of the components inside your PC.

Thermal throttling is a genuine issue for a number of different users.

Power users who like to render 3-D models, architects 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.

Stock Cooler vs Premium Cooler

A third-party CPU cooler is definitely needed to push the processor to its boundaries.

PC Overclocking: If you are looking to overclock your processor, a third-party CPU cooler becomes a necessity rather than an option.
(Stock coolers are not capable of handling that amount of heat generated by performance.)

Noise Levels: You may also want a third-party CPU cooler to keep the noise levels down. (Some stock CPU coolers can get a little noisier depending on how noise proof your chassis is, so it makes sense to invest in a better and cooler CPU cooler and reduce the noise.)We’ve included a lot of different CPU coolers that provide almost silent operation so if you’re looking to build a nearly silent PC, there are a lot of great options available.

Gaming PC Looks: If you are a person who prefers a certain look when building a PC, a stock cooler will look downright ugly to you. So getting a customizable or even a better looking third-party CPU cooler is the best way to go.
(There are some downright gorgeous looking CPU coolers of 2021 so it will be easy to go for the one that perfectly fits your needs.)

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.

Air CPU Coolers

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.

These are the most common CPU coolers you’ll find in the market.

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

Water CPU Cooler

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.

There are several reasons for their unpopularity.

The biggest one is the installation process which can be cumbersome for a lot of users, and the 2nd is the chance of them leaking and potentially destroying your whole build.

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.

AIO CPU Cooler

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 exact 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°.

We tested around 16 different CPU coolers that the ordered based on research and then tested them all out one by one.

It took a little while to completely test them, especially because we ran several benchmarks as well as ran organic tests on it.

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 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.
