Best CPU Cooler For i9 9900k Buying Guide:

One of the most important parts to consider in any gaming rig is the CPU. The Intel Core i9 9900K has a base speed that tops out at 3.6GHz and can go up to 5GHz with Turbo Boost, but if you don’t have a cooling system for it, then your computer will overheat and crash. All your money will go into vain within seconds. We have presented one of the best CPU coolers above. Go and take a look over them and select anyone according to your taste. 

Here are some of the main points that are important to take a look on: 

Air VS Liquid Cooler:

Air coolers are great for keeping your CPU nice and chilly, but they’re not perfect. Air-cooled systems have a higher internal temperature because the heat is dispersed elsewhere within the computer’s case instead of outside it. Liquid cooling offers an interesting alternative by taking care of that pesky problem with its radiator fans to push all that hot air into wintery coldness.

Noise Level:

If you don’t want to be disturbed when everything around is quiet and calm, make sure your CPU cooler does not produce an irritating sound. A good option for a quieter model should produce less than 30 decibels. all the CPU coolers we have presented above have minimum noise level and are totally silent when there is no such overclocking. 


CPU coolers are a vital part of your PC system. They work to dissipate heat that is accumulated by the processor in order to protect it from being damaged. The fans, radiators, and other components inside these cooling pieces provide an opportunity for this excess energy to be released without damaging any hardware. The radiators are of different sizes, and the price of the CPU cooler can also be varied by its size.
