Deepcool AK400 air cooler review
Is it as good as AK… 47? 

Today, we are reviewing an air cooler from Deepcool; it’s an AK400. The AK400 is from the same family as the AK620 (a dual-tower cooler). The previous product of this type (air cooler) covered was the AS500, tested back at the end of 2020. It was so good (it earned the “Approved” award) that it stayed as a part of the chassis test suite.



This time around, it’s also a single tower design cooler, with a four heat pipe tower layout, a unique matrix fin design, and a high-performance FDB fan that should provide excellent heat dissipation and low noise levels. The Deepcool AK400’s fan has an extensive RPM range of 500 to 1850. The maximum airflow is 66.47 cfm, with the noise levels not exceeding 29 dBA. The four heat pipes are 6 mm thick. Thanks to the cooler’s slim design (45 mm), there shouldn’t be conflicts with RAM sticks. The high fin density and the performance shouldn’t be an issue in most scenarios. There’s no available RGB this time.



The Deepcool AK400 is compatible with the following CPU sockets:

  • AMD – AM4
  • Intel – LGA1700/1200/1151/1150/1155 

We want to underline that now we’re using the Alder Lake processor to check the cooler (previously, there were Intel Core i9 9900K and the 10850K). We’ll check if this cooler will handle the AMD Ryzen 7 3700X and Intel Core i9 12900K? The warranty period is three years. The price of AK400 is 30 USD. Yes, it sounds cheap at first look. But, will it be worth it? So let’s head to the specs/feature page, shall we?
