Things to consider before buying the Best CPU Cooler for i9 9900K

Consider the following factors before buying a CPU cooler for an Intel i9 9900k.

Air vs Liquid: Choosing whether to use air and fans to cool your CPU or a liquid loop is the main decision you’ll need to make.

For serious overclockers who like to tinker just as much as they like playing games, liquid AIO cooling is a better thermal solution than fans. However, liquid cooling can be quite costly.

Compared to air cooling systems, fan cooling systems tend to be less efficient, but they’re cheaper, and if they’re properly designed, they’ll still do a great job of keeping your CPU cool.

Socket: The issue of compatibility isn’t just with motherboards and CPUs, but with anything you wish to connect to your motherboard as well. For your thermal solution to work, it needs to have the correct socket.

Many coolers have universal attachments that work with most modern motherboards, but some are designed specifically for one type of socket. You should always keep your motherboard socket in mind when shopping around and never buy a cooling system until you have seen a list of the cooling system’s compatible sockets.

Dimensions: Each type of fan has different dimensions and clearance requirements. Some CPU coolers have low-profile designs that require very little space. You won’t have to worry about them blocking RAM slots or touching the case wall. However, such designs are extremely bulky. Before buying one, make sure your case has ample clearance space.

Volume: As liquid loops run very quietly, you only need to consider the volume of fan cooling systems. If you have a lot of fans running at high speeds, your CPU will be fine, but the case will sound like a jet engine.

Choose a fan that is designed to run quietly if you wish to avoid this cacophonous fate. There are even some models equipped with automatic fan stop technology that turns them off when not in use.  Noise isn’t a huge factor for gamers who use headphones, but if you prefer to listen to standard audio, you should consider the fan running volume.

RGB: RGB means Red, Green, and Blue colors. LEDs emit millions of different shades by combining different levels of these three primary colors. Similar to Marmite in the world of PC gaming, people seem to either love or hate them. Customizing your case with RGB fans lets you add some personality to it. If you sync your RGB peripherals, you can create mesmeric light sequences that can make gaming even more intense and captivating.


 It is recommended that you choose one of the above coolers if you have recently purchased an Intel i9 9900k processor and are trying to find the best CPU cooler for the Intel i9 9900k processor. A CPU cooler can be purchased at a lower price for those with a lower budget and at a higher price for those with a higher budget.

 It is currently the fastest, most powerful, and most reliable processor available on the market, which is the Intel Core i9 9900K. It is important to get the latest processor regardless of whether you are a professional gamer or a casual user. Because of its high-end features, the device tends to heat up quite quickly when it is used. The primary requirement for preventing this issue and ensuring that your device continues to operate at its best is a CPU cooler. The top best CPU coolers for the i9 9900k have been discussed above along with their advantages and disadvantages. To get the best performance out of your computer, I recommend that you choose one of these options.  

Frequently Asked Questions

Can you air cool an i9?

At stock settings, the Intel i9-10900K isn’t a scorching hot CPU at 125W, so decent air cooling will suffice.

Is air cooling better or liquid cooling?

Air coolers are quite effective at removing heat from the CPU, but they also disperse heat into the case. The system’s overall temperature can be raised as a result. The fans on the radiators in liquid coolers do a better job of transferring heat outside of the system.

Does i9 9900k need liquid cooling?

Intel’s i9-9900k is a powerful processor. As it produces much power, it can overheat frequently, so you need a cooling system to compensate for the heat. The liquid cooling capabilities are an alternative to traditional fans, particularly in heavy-duty applications.
