At its core, the Deepcool AK400 Zero Dark Plus Black features four Ø6 mm direct-touch copper heat-pipes arranged in an optimized layout paired with a matrix-style fin stack.
This design promotes efficient heat removal from the CPU’s integrated heat spreader and transfers it through the fin array into the airflow generated by the twin 120 mm fans.
With a rated dissipation performance of up to 220 W, the Deepcool AK400 Zero Dark Plus Black is well suited to support contemporary high-performance CPUs from both Intel and AMD platforms.
The cooling solution includes two fluid dynamic bearing (FDB) 120 × 120 × 25 mm fans with a PWM speed range of approximately 500-1650 RPM.
Under full load, the noise remains very low at ≤ 28 dB(A), making this Deepcool AK Series Desktop Cooler suitable for builds where quiet operation is desired.

Airflow of about 59.46 CFM combined with static pressure of 1.62 mmAq ensures the fin stack is well ventilated.
Installation is straightforward thanks to the all-metal mounting bracket and a step-by-step five-step process designed for convenience.
The cooler comes with pre-applied high thermal resistance paste, saving time and ensuring proper heat interface right out of the box.
Compatibility is broad: Intel sockets including LGA1851/1700/1200/1151/1150/1155, and AMD sockets AM5/AM4 are all supported, making it ideal for many current systems.
With total product dimensions of 127 × 123 × 155 mm and a net weight of 802 g, the Deepcool Zero Dark Plus Desktop Cooler is substantial yet still suitable for many standard mid-tower cases.
The fully black aesthetic presents a clean, unified look and helps the cooler integrate seamlessly into modern system builds.
The Deepcool Single Tower Powerful Desktop Cooler strikes a convincing balance of performance, design, and compatibility.

If you’re seeking an air cooler that offers strong thermal capability without the excess size of a large dual-tower design, while also keeping noise low and visuals clean, the Deepcool AK400 Zero Dark Plus Blackis a compelling choice for your build.
