DeepCool AK400 Zero Dark CPU Cooler

DeepCool AK400 Zero Dark is an air CPU cooler aimed at mid-range and more serious gaming and work configurations, where you seek stable temperatures without unnecessary lights and colors. With a cooling capacity of up to 220 W, it easily handles most modern processors, even under higher load. The compact 120 mm fan combined with decent static pressure and airflow provides a good balance between noise and efficiency. The “Zero Dark” version comes without RGB, making it ideal for clean, dark builds.

What you get

You get air cooling with 1 x 120 x 120 x 25 mm fan, which operates in a range of 500 to 1850 RPM, allowing quiet mode under low load and more aggressive airflow during gaming or rendering. The maximum airflow of 66.47 CFM and static pressure of 2.04 mmAq help dissipate heat from the radiator effectively, which is important for denser fins and higher TDP CPUs. The noise level of up to 29 dBA means that even at higher speeds it won't turn into a “turbine” in the case. Thanks to support for the most popular sockets, you can easily move it between different platforms without needing a new cooler.

• Air cooling from DeepCool with a capacity of up to 220 W, suitable for powerful gaming and productivity processors.
• Universal compatibility with modern and older platforms: AM4, AM5, LGA 1700, LGA 1200, LGA 115x, LGA 1851, providing flexibility for upgrades.
• One 120 mm fan with dimensions 120 x 120 x 25 mm – standard format, easy to replace or add to the airflow in the case.
• Wide speed range of 500–1850 RPM for automatic balance between silence in idle and cooling under load.
• Good airflow of 66.47 CFM, which helps effectively dissipate heat from the radiator even in more compact cases.
• Static pressure of 2.04 mmAq, suitable for dense towers and configurations with limited airflow.
• Maximum noise level of 29 dBA, which is reasonably quiet for a 120 mm cooler under full load.
• 4-pin PWM connector for precise control of speeds through the motherboard and automatic cooling profiles.
• Lack of RGB, ideal for minimalist, “stealth” builds or if you simply don't want a glowing circus in the case.

Who is it suitable for

AK400 Zero Dark is a good choice if you are building a mid-range or more powerful gaming/work computer and want serious air cooling without RGB effects. It is suitable for an upgrade from a stock cooler, as well as for a quieter machine that can handle prolonged gaming sessions or rendering. If you are aiming for extreme overclocking or a completely silent system under full load, there may be more suitable high-end or water solutions.

The most sensible aspect here is the combination of up to 220 W cooling capacity, reasonably low noise, and wide compatibility with sockets, all packed into a clean, unlit package. You mount it, set the fan curve, and forget about the temperatures.
