Best CPU Coolers in 2021
Keeping your hardware, especially the vital parts such as the processor, cold is one of the major priorities when we are talking about the computers. Therefore, CPU coolers present a very important part of any custom PC build, and particularly, overclocking machines.
Choosing the best CPU cooler isn’t any easier than choosing the best PSU or the best RAM. It all comes up down to what you need and want, and of course, what level of investment your wallet allows. Since there is a wide variety of shapes, sizes and features, these searches have a tendency to turn into an exhausting and time-consuming marathon that nobody wants.
Because we know that, we’ve come up with a list of a couple of things to pay attention to when buying a CPU cooler. This should help you at least a little in your search.
Best Air CPU Coolers
Best Liquid CPU Coolers
How to Choose a CPU Cooler
Type of a Cooler
The choice between the air cooler and the liquid one mostly depends on your budget and what it will be used for. If you can, and if you are into overclocking, always go for the liquid solution – they generally offer better performance but cost more. On the other hand, there are air coolers that will do a decent job for much less money.
Among the most important aspects of any CPU cooler is its socket support. You can have the best CPU cooler at your disposal, but what is the point if it doesn’t fit your motherboard. Therefore, do your “homework” and there will be no trouble.
Some people don’t care about it, others can’t stand it. Because of that make a decision according to your preferences and, of course, your budget, but also be aware of the fact that noise can increase stress levels and negatively affect your psychic. Therefore, generally go for the more silent ones.
The last thing you need is a piece of hardware that cannot fit into your rig, so be careful about what you buy and be absolutely sure it can be installed inside of your PC case.
RGB lighting by itself isn’t that important from the practical point of view, but solely for esthetical reasons. They are just cool, simple as that. Nobody really needs them, but everybody wants them.
Best Air Coolers
Simply the Best CPU Cooler Money Can Buy
Things are pretty much straightforward when talking about Noctua NH-D15. This is just the best CPU air cooler you can buy. Its performance can be compared even with a large number of liquid coolers and many of them, such as DEEPCOOL Gamer Storm Captain 240, Cooler Master Nepton 240M, and Corsair H100i GTX, etc. are outperformed in both noise levels and cooling efficiency.
Thanks to the great design, which is inspired by its highly successful predecessor D-14, and with the help of a dual tower heatsink and two great 140mm airflow fans, Noctua NH-D15 delivers great cooling results, and at the same time, a quiet work even at full loads. On top of that, it supports almost all the sockets beside the AMD AM4.
Basically, the only downsides of this cooler are its bulkiness, and the price, which is among the highest of all the air coolers. On the other hand, when you look at its performance and the fact that it can compete and beat some of the best liquid CPU coolers out there and that its price, although high, is just a fraction of the liquid cooler pricing, you come to the conclusion that it is actually worth that money.
- extremely quiet
- six years warranty
- the package includes dual 140mm fans
- too big for some configurations
DEEPCOOL GAMMAXX 400
A Great-Performing CPU Cooler that Blasts with its Affordable Price
DEEPCOOL GAMMAXX 400 isn’t among the “cool looking crowd” of the CPU coolers, but its performance beats most of the competition, such as Noctua NH-U12S and Be Quiet! Shadow Rock Slim, by a wide margin. When its great performance to price ratio is also taken into consideration, the advantage over the rivals gets even bigger, positioning it as the best CPU cooler under 50$ you can find for your rig.
With support for all the mainstream sockets and equipped with a 120mm airflow fan and a tower heatsink with four copper heatpipes for a faster heat distribution, DEEPCOOL GAMMAXX 400 presents a great option for any enthusiast out there. Its modest two-year warranty maybe doesn’t offer much confidence in its longevity, but when you realize that you can buy two of these for the price of one Noctua NH-U12S, or Be Quiet! Shadow Rock Slim, its value becomes even higher.
- great cooling
- excellent value for the money
- moderate size
- a bit loud
- it looks slightly unfinished

Cooler Master MasterLiquid ML120R
The Master of Cool Looks among the CPU Coolers
Since most of the liquid coolers are pretty similar, manufacturers are trying to find ways to make their products stand out from the crowd. In the case of Cooler Master MasterLiquid ML120R, they have done it through its super cool RGB lighting. Thanks to the 28 LEDs positioned all across the pump and the fans, this cooler offers high customization of lighting, allowing for unique and versatile light effects. The only problem with all those LED lights is the amount of cabling, that can prove to be a bit troubling.
Other than the great RGB LED performance, this CPU cooler doesn’t offer anything brilliant. It is easy to install, it supports the majority of the modern socket types, its 120mm fan radiator delivers solid performance, but overall there is nothing that separates it from the whole bunch of similar products. Cooler Master MasterLiquid ML120R isn’t the best budget CPU cooler, or the best closed-loop CPU cooler. This is a cool looking but a limited piece of hardware. If that’s fine with you, go for it, but before that just think through it all one more time.
- eye-catching LEDs
- quiet pump
- good cooling
- questionable software quality
- too many cables
