On the bench today is the DeepCool AK400 (R-AK400-BKNNMN-G-1), a new budget-friendly CPU cooler launching today from DeepCool. It is presented as a single tower version of their popular AK620 High-Performance Dual Tower CPU Cooler and they’re offering it at a very competitive price of $34.99 MSRP. We’ll strap it to our air-cooling test platform that is built around a Ryzen 7 2700X processor with a manufacturer-claimed TDP of 105W. This should provide a reasonable usage case that we are likely to see with some of today’s most demanding air-cooled CPU coolers.

DeepCool AK400 Overview

The DeepCool AK400 cooler is an air cooler that is designed to work on the most current consumer class of sockets, including Intel’s LGA1700/1200/115x and AMD’s AM4. If you’re hoping for compatibility for your old Bulldozer or perhaps that HEDT chip you still have chugging on an X99 platform, you’ll be out of luck here. The DeepCool AK400 features up to 220W of heat dissipation efficiency.


DeepCool AK400 sports four direct touch copper heat pipes which mostly cover the nickel-plated copper base to allow for heat dissipation. The pipes extend up into an aluminum dual tower that has a 120mm fan attached. The assembly is nickel-plated with a topping of a textured black element with Deep Cool’s logo across the top. It is also offered in a white version.

DeepCool leverages a unique matrix fin design with matrix-shaped fins on the heatsink to sport a unique and high-end aesthetic. It is also fairly short, measuring 155mm in height.


DeepCool included a single fan with the unit, one of their FC120P models.

The 120mm fluid dynamic bearing fan (FDB) is rated for 1.56W of power, a noise level of less than 29 dB(A), a rotational speed of 500-1850 RPM, and a maximum of 67 CFM at 1.8W of power, and the quoted operational lifespan is 50,000 hours. It delivers airflow of 66.47 CFM at a fan pressure of 2.04 mmAq at full blast.

The DeepCool AK400 presents itself as being higher-end than its price tag of a suggested $34.99, while not filling up the entire space around your CPU. There’s no RGB to be found on this – it’s just here to do its job.
