8 Best CPU Coolers for Core i9-12900K (LGA 1700 Compatible)

It’s been a tough few years for Intel. They had their reign as the King of processors come to a humiliating end when AMD rose up and defeated them in battle after battle until finally besting them once again with new Alder Lake CPUs. Still, Intel soldiers on and indeed seem to have a new lease on life with their latest processor architectures. One such example is the Core i9-12900K.

Sitting at the top of the Alder Lake lineup, the Core i9-12900K is very much a modern enthusiast-level CPU. It packs a total of 16 cores and 24 threads. Similar to the other Alder Lake processors, the Core i9-12900K features the new hybrid design, where it divides the cores into two groups with one group optimized for high performance and the other group optimized for efficiency. In this case, the total CPU cores would be split into 8 highly-optimized performance cores and 8 efficient cores to give you a perfect blend of great performance per core and maximum efficiency.

The Core i9-12900K can operate at a top turbo frequency of 5.10 GHz (on P-Cores), which makes it the highest performing processor in terms of single-thread processing in existence today. With its fast clock speeds and high core count, it is likely to perform well even with demanding games and intensive applications.

However, the Core i9-12900K is not without its flaws as well, as is with every other CPU in existence. You’ll expect it to run quite hot especially under load with its 125W TDP. And since the Core i9-12900K doesn’t come with a stock cooler, you need to buy an aftermarket cooler. And a good cooler will go a long way in ensuring you get the better temperature and operational performance from your CPU.

For you to get the best cooling performance of your Core i9-12900K, we’ve listed some of the best coolers that work well with it. We have also included a buyer’s guide at the end of this article to help you make a better purchasing decision.
