About Deepcool AK400 Digital Black Air Cooler

Featuring four direct-touch 6 mm heat-pipes arranged in a single tower layout, the Deepcool Digital Series Black Air Cooler is designed to efficiently channel heat away from the CPU base and into a full fin stack for dissipation.

This design is paired with a 120 mm PWM fan whose speed range goes from 500 RPM up to 1,850 RPM, delivering an airflow figure of approximately 68.99 CFM and static pressure of around 2.19 mmAq—providing the thermal headroom to tackle higher-power CPUs comfortably.

The Deepcool Digital Black ARGB Air Cooler is rated for noise levels up to only ~28 dB(A) under full spin, which makes it especially attractive for users who want strong cooling without the roar of large high-speed fans.

Installation and compatibility have been thoughtfully addressed: the Deepcool Single Tower 120mm Desktop Cooler supports Intel’s latest LGA 1851/1700/1200/1151/1150/1155 platforms, as well as AMD’s AM5 and AM4 sockets, offering flexibility for upgrade paths.

The overall dimensions of ~126 × 97 × 156 mm ensure that the Deepcool AK400 Digital Black Air Cooler remains compact enough to fit in many mid-tower cases, and the RAM/PCIe clearance is well managed thanks to the non-overhanging design.

The net weight of 695 g keeps it fairly light compared to larger dual-tower models, reducing stress on the motherboard.

On the aesthetic front, the “Digital Black” version elevates the package by including a dedicated status display at the top of the cooler for real-time monitoring of CPU temperature/usage—an appealing feature for enthusiasts who like to keep an eye on system health.

This display is combined with addressable RGB lighting for style, enabling the cooler to blend into modern RGB-equipped builds.

The Deepcool AK400 Digital Black Air Cooler is mounted using metal clips, and the heatsink includes pre-applied thermal paste, making the installation process more straightforward.

From a performance perspective, reviewers have noted that the Deepcool AK400 Digital Black Air Cooler punches above its size class: in testing it has handled thermal loads exceeding 200 W while retaining reasonable noise levels.

The compact footprint means it does not interfere with tall memory modules, making it a very memory-friendly cooler in builds where RAM height matters.

Overall, the Deepcool AK400 Digital Black Air Cooler stands out as a balanced solution: great compatibility, solid thermal performance, quiet operation and modern features (display + ARGB) in a compact form.

For users building a powerful yet clean-looking PC without going into massive cooler territory, it offers an excellent combination of value and functionality.
