CPU Cooler for I9 9900k Buying Guide

There are some factors you should consider before buying a CPU cooler for i9 9900k. Some people who are a proficient gamer, you will have an idea to determine what you need to find and what is the best for you. How about the beginner? The beginner, sometimes, feels confused due to a matrix of CPU coolers. Hard to know what is the best and how to choose. The first thing a beginner should do is to find and check all technical aspects before settling his payment.

So, what are aspects to think about? Here are they:

You have to know what you need

Are you a gaming enthusiast? Or are you a pro-level multi-taskers? If you are, your computer needs to operate frequently, even every time. It means your CPU gets warm-up commonly. And going to need a high-end cooler is necessary. On the other hand, you are not from that genre, a high-end cooler seems to be a waste of money. You just need a budget-friendly cooler at all.

Choose air cooling or liquid cooling?

On the market, we have two primary cooling systems available: air cooling and liquid cooling. What is the better one? Each of them has its advantages and disadvantages.

Air cooling is the traditional cooling system. It includes a big metal heat sink and a fan. This fan is used to push the air away from your processor. If choosing this system, you have to check the CPU’s socket type, then ensure that its dimension is compatible with the PC case.

The second option is the liquid cooling system. Liquid cooling absorbs more heat than air cooling. How does this work? It transfers cooling liquid from the processor to the fan in a circle. In this way, the hot air is removed from your case.

Compared to air cooling, liquid cooling works more efficiently. And it doesn’t produce the noise so much while operating. However, liquid cooling is not cheap. If you have a low budget, consider taking the air cooling system.

The noise

When a CPU cooler operates, it can produce an irritating sound that makes you feel annoyed. To avoid this circumstance, ensure that your chosen cooler produces the minimal decibel of sound.

CPU socket

Most CPU coolers for i9 9900k are compatible with traditional sockets that we usually use in our house. But some models require specific sockets. Being compatible with common sockets is convenient for all of you when using the CPU cooler for the processor. Therefore, you should check to ensure that your chosen cooler is compatible with sockets or meets other requirements related to sockets.


If you want to overclock the i9 9900k, the requirement for the cooler is different. Some people are extreme overclockers, AIO liquid cooler will be the best option.

Below are other notes you should remember:

  • A CPU cooler with many fans results in better cooling. But it produces more noise.
  • Don’t skip air cooler if you are searching for both effective and budget-friendly. It is not modern but it is still the best choice. Easy to purchase an air cooler with 240MM AIOs. This cooling power is perfect to cool an i9 9900k.
  • Pay attention a bit to RGB settings!. These settings can be done with your cooler’s software. So, ensure that you can adjust the RGB setting (the mode or turning on/off).
  • The RAM slots can prevent the installation of long RAM sticks of an air cooler. A big and dual-tower air cooler can solve this problem by blocking the RAM slots.


1. I need a CPU cooler with a high-power performance, so, which type should I choose? Air cooling or liquid cooling?

In this case, the air cooler is not ideal. The liquid cooler is the better choice.

2. Which fans to choose?

On the market, there are three basic main types of fans. They include:

  • PWM fans allow to change RPM and keep the running volume down.
  • DC fans are known as subunits of PWM fans.
  • Molex fans are not quite when operating. But its advantage is the cheap price. A plus point for anyone with a low budget.

3. What is the safe temperature for my i9 9900k?

The ideal temperature for this processor should be below 80⁰C.

4. Is it forced to have a CPU cooler for i9 9900k?

A cooler for i9 9900k is not required. But you are advised to have it because it can help to improve CPU quality and lifespan.

5. Should I choose liquid cooling?

Many people have the same question. They are wondering if a liquid cooler is better or not. Don’t worry and think so much because liquid cooling is a great way to cool your CPU. It doesn’t make irritating noise, too.

Wrapping It Up

As mentioned above, Intel Core i9 9900k is the best gaming processor and quickest desktop processor. Improving its performance and lifespan is very meaningful. A cooler can help this. So, choosing the best CPU cooler is always important. Hope that our useful information and the list of top 5 best CPU cooler for i9 9900k above will help you to make the right decision when looking for a good CPU cooler.
