Our Thermal Benchmarks

To bring you the top coolers for i9-12900K, we tested several of them, and here are our benchmarks:

How We Choose These CPU Coolers For i9-12900K

Picking the best CPU cooler for the i9 12900K is serious business as you have to consider a variety of factors:

• Performance: The most important consideration is, of course, performance. You have to make sure that the cooler is adequate to keep your CPU running at ideal temperatures and not reach its throttling limits. For that, you also have to consider your workloads, which decide just how much you’re going to be pushing your CPU, and whether you’ll be overclocking or not.
• Aesthetics: Normally, the second most important factor considered by most users is aesthetics. You don’t want a cooler to simply perform good, you also want it to look good. For that, its design, color theme, and presence or absence of RGB are the key factors considered.
• Budget: We all want the best-performing cooler but that’s often not possible due to budget limitations. You have to consider your budget, narrow down all the options available within that budget, and finally pick the best option according to performance, aesthetics, and other factors.
• Noise Levels: Acoustical performance is another important consideration. You have to make sure your cooler can adequately handle your CPU’s temperatures, and at the same time keep the noise level at a point where it’s not disruptive. More (and larger) fans lead to more noise, but you can run them at lower speeds since you’re getting more performance anyway.
