The only drawback of the i9 9900k is its powerful processor that tends to heat up fast. If you are a pro gamer that is using i9-9900k and you are looking for the best CPU cooler for i9-9900k then you are at the right place. I am going to tell you everything you need to know about the 10 best CPU cooler for i9 9900k.

CPU comes in different shapes and sizes some are sleeker, small, and thin at some time some are robust and sturdier. Some costs more, few are reasonable, others have high proficiency and some exist with better noise management. In short, there is a large number of CPU coolers available in the market, and it is quite difficult to make the right choice.

We will guide you comprehensively so that you would be able to choose the best cooler for your i9-9900k that would work proficiently to maintain the temperature of the CPU. By using these CPU coolers you can maximize the performance of your processor. 

Which is the best CPU cooler for i9 9900k? Air cooler or liquid cooler?

When it comes to CPU coolers there are two basic types. One is the air cooler and the second one is the liquid CPU cooler. The choice of either liquid or air CPU cooler can be made by looking at the task and the load of work you are going to put on your processor. For instance, playing AAAA+ video games with high resolution and refresh rate and at the same time the heavy graphic art of the game will toast your i9 9900k, so you need to choose a proficient CPU cooler for your i9 9900k. You can easily choose by looking at the following facts.

Air cooler for CPU

The air coolers for the CPU are the ancient ones. The air cooler consists of two main components: heat sink and heat pipes. Heat pipes move the heat from the base of the cooler to the heat sink. From the heat sink, heat is expelled out into the air with the help of an airflow system and fans. 

Liquid cooler for CPU

The liquid CPU cooler is not an old innovation. Liquid coolers have tubes in place of heat pipes. These tubes are filled with thermally conductive liquid that surrounds the CPU. The liquid CPU cooler constantly moves the cooler liquid in the CPU and pumps out the hot liquid that is cooled by the radiators before pumping it back. This process keeps the CPU cool. 

Both the liquid CPU cooler and the air CPU cooler when properly installed are highly effective tools to maintain the temperature of your i9 9900k. But there are different factors to consider in diverse circumstances. 

Price: The price is one of the most important factors. Generally speaking, air cooler cost much less than liquid coolers. Also, both have premium and entry levels depending upon their advanced features. 

Size: Air CPU cooler can be bulky but it would be limited to one area only. While on the other hand, for a liquid air cooler you need to have a separate space for the radiator and there are also issues of maintaining proper orientation of the coolant tubes and radiator. So, maintaining an air cooler would be easier.

Sound: A CPU cooler is prone to create a high pitched irritating sound while operating. The sound is due to the high speed of the fans. If you are looking for a silent CPU cooler for i9 9900k then a liquid CPU cooler is the best choice for you. Air CPU coolers are noisy, although the innovations have lessened the noise to a level still the silent working feature of the liquid cooler cannot be overlooked. 

It is a common belief that a liquid CPU cooler is better than an Air CPU cooler but it is not always the case. Different tests have shown that some air coolers can surpass the speed of liquid coolers. 

To save you from the headache of choosing the best CPU cooler for your i9 9900k we are going to provide you with the complete details of some best cooling solutions for i9-9900k.
