On the other hand, if youโ€™re planning a flashier build, completely illuminated with RGB, the DeepCool AK620 will be quite lackluster with its dark color and lack of appealing designs. However, it’s to be expected with its lower price.

Although it doesn’t have the best aesthetics, I couldn’t take my eyes off the cooler because of its sleek design and this is what I said during my review:

“The DeepCool AK620 is a sleek and visually appealing 120mm air cooler, part of the DeepCool ecosystem, with a dual-tower design and high-quality build. While it lacks RGB features, itโ€™s excellent for neutral builds and offers compatibility with most mid-tower chassis.

Why We Didn’t Go For These Best CPU Coolers?

Out hardware experts have tested numerous CPU coolers, but not every product can make the cut. Here are a few honorable mentions that couldn’t make it to the list.

Important CPU Cooler Key Terms

If you’re confused by various CPU cooler terms we used in the entirety of the article, here’s a short list of the most common jargon terms:

  • TDP: It is a presumed measurement of the heat a processor generates while operating. For CPU coolers, these values are the heat the cooler can dissipate.
  • FPI: Stands for Fins-Per-Inch. It is a reading to check the fin density in CPU coolers. The denser a radiator is, the better the thermal cooling it can provide.
  • Heat Pipes: Exclusive to air coolers, heat pipes are the pipes that transfer heat from the processor to the cooler, which then dissipates it outside. More heat pipes equate to more heat transfer.
  • PWM: Also called Pulse Width Modulation, is a CPU fan type that can regulate speed based on certain voltage readings.
  • RPM: Also called Rotations Per Minute, it is the value through which we can calculate the speed at which a CPU fan runs. Higher RPM values can equate to better cooling but more noise.
  • CFM: Short for Cubic Feet Per Minute, CFM defines the amount of air a CPU fan can distribute within a minute. Bigger but slower fans can have more CFM than smaller but faster fans.

CPU Coolers Benchmarks

Here’s a list of benchmarks we have conducted to back our claims for the awards we have enlisted for the CPU coolers. The benchmarks show comparisons against other coolers and how the ones we awarded fare. We have used the Intel Core i7-10700K and the Intel Core i7-13700K processors to conduct the following tests.

How We Test CPU Coolers

There are various rules we at Tech4Gamers follow when testing CPU coolers. For example, performance, noise, aesthetics, build quality, and compatibility are a few factors we look at. Please read through our detailed blog on how we test CPU coolers to know more about our testing methodologies.

  • Performance: For the most part, the thermal performance of a CPU cooler is the main reason we test coolers. It’s the job of a cooler to dissipate heat, and the more it can dissipate, the better it is. We compare CPU coolers with their competitors in a closed environment with the same build at different clock speeds to achieve optimal results.
  • Noise LevelsAnother aspect to consider when testing CPU coolers is understanding their fan noise. While it goes unnoticed by many, noise from a case fan can be extremely distracting for many consumers. Therefore, we ensure that every CPU cooler’s noise is tested so you don’t have to buy a noisy cooler.
  • Aesthetics & Build Quality: While most consumers look for aesthetics, the build quality of a CPU cooler is also important. CPU coolers have all aesthetics, from slim to sturdy looks and from RGB to stealthy models. Moreover, a good quality build ensures the longevity of the CPU cooler.
  • Socket CompatibilityCompatibility is another important testing measure. While most CPU coolers are compatible with modern processors, a few might skip a generation’s compatibility. Therefore, we ensure a CPU cooler is compatible with most processors.
