The best CPU cooler for the i9 9900k

The Intel i9-9900K is not the newest and best Intel CPU, but it is still the top model of 2019 and therefore one of the best gaming processors on the market. In this article, we try to introduce some of the best CPU cooler for the i9 9900k

Only with the flagship LGA 1200 models such as the flagship Core i9-10900K and 10700K, the 9900K can still compete with the latest CPUs and get out, not a winner, but a medal in the neck.

This octa-core and 16-core processor can also break the 5 GHz limit and achieve significant performance jumps in thermal costs.

In other words, if you want to get the 9900K to its maximum speed, you have to equip it with a powerful cooling system.

However, you do not need to use a liquid AIO cooling system when overclocking.

Remember that you can use an expensive air conditioner to overclock 9900K. You can easily reach 5 GHz without any problems with a large piece of air cooling metal such as NH-D15, Dark Rock Pro 4, Deep Cool Assassin II, or some other mixtures.

Consequently, it is important to get the maximum benefit from the processor that can be achieved by overclocking and pushing its credentials.

Factors to consider when buying the best CPU cooler with the i9 9900k

If you are a good gamer or overclocker, you probably have a better idea when buying a CPU cooler. It is still important to use the checklist at least once in a while. Beginners need to be well-versed in the technical aspects before making their first purchase.

Here are some tips to help you get started:

What exactly do you need?

If you are a gamer or a multi-level professional, CPU overheating is quite common. Also, if you have an Intel i9 9900K installed, you definitely need a high-end air conditioner. Conversely, if you are not a fan of it, a budget cooler may be right for you.

Air cooling versus liquid cooling

There are primarily two types of cooling systems, including air cooling and liquid cooling. Liquid cooling is able to absorb more heat than a traditional air cooling system.

However, it is relatively expensive. If you do not have enough budget, you may want to choose an air conditioner processor.

Also read:

The air conditioner comes with a large metal tank and a fan that blows air away from the processor. To do this, you need to check the type of CPU socket and make sure that the dimensions are compatible with your computer case. While the sound should be on the box, CPU fans do not need to be loud.

Air cooling versus liquid cooling

This is definitely something you want to check out before committing to a purchase. The second choice is the liquid cooling system. These are often referred to as all-in-one or AIO liquid coolers.

They circulate the coolant from your processor to the fans, which helps keep hot air out of the case.

Liquid coolers are more efficient and are normally quiet. However, they are a bit difficult to install and cost more.

Depending on your preferences and budget, choose the right option that goes back to what you feel comfortable with.

An effective cooling mechanism makes the most of your computer and also maintains the temperature during long sessions of the game. It is important to make sure your system has the best airflow when choosing the best processor cooler for the i9 9900k.

Universal CPU socket

Most CPU coolers in this guide are compatible with traditional sockets. However, certain models require special sockets. Make sure you are familiar with them and have the rules to meet the need.

Avoid noise

A CPU cooler tends to make an irritating sound when everything around you is quiet. You should preferably choose an air conditioner that produces at least a decibel of sound, such as the Corsair Hydro Series H150i Pro Liquid CPU.
