Things to Consider when Buying a CPU Cooler for i9-9900k

Things to Consider when Buying a CPU Cooler for i9-9900k

Now that desktop processors and motherboards are becoming more powerful thanks to technological advancements, investing in a high-end CPU cooler has become increasingly important. PC users who neglect vital points and do not buy a good cooling solution may face severe performance issues in the long run. Since ensuring proper CPU cooling is imperative, you must be extra careful while choosing a CPU cooler if you really want good value for your bucks.

It is true that people who are not tech-savvy enough are bound to face various difficulties when it comes to finding a top-notch CPU cooling system. This is the main reason why we have come up with this comprehensive CPU cooler buying guide to make things a little easier. Given here are the 4 important things that you must take into consideration while buying a CPU cooler.

CPU Socket

Different PC coolers are designed for different CPU sockets and hence, you must opt for a product that is supported by your system. Being cautious is necessary because certain cooling solutions support only a limited type of sockets. Thoroughly go through the specifications of the PC cooler you are planning to purchase and find whether it can be fitted in your CPU socket or not. 

Size and Bulkiness

Take note that there are some CPU coolers that do not fit in every PC case owing to their big size. Based on your individual needs, you need to determine which CPU is the best for your cabinet.

Remember to go for a premium CPU cooler that is less bulky and has the right size simultaneously.

Air Cooler or Liquid Cooler?

Without a doubt, keeping PC components cool and stable is a very effective way to increase the overall lifespan of your system. However, you must choose the right type of cooler to get the results. While an air cooler should be enough to meet your needs but if you execute resource-heavy tasks that make your PC run at extremely high temperatures, going for a liquid cooler would be your best bet.

Noise Levels

Another thing you need to ensure is that the CPU cooler you buy should have low noise levels so that you do not get disturbed while the cooler does its job. It has been observed that coolers that have large fans make less noise as compared to coolers equipped with small fans. Make sure that you pick out a PC cooler that will provide you with the best cooling performance without being loud.

Conclusion – Which is the Best i9 9900k CPU Cooler?

Upon testing each of the aforementioned coolers, the Corsair Hydro Series H150i stands out as the best AIO for i9-9900k. It is a total package when it comes to a combination of excellent cooling, superior design, and looks.
