Air cooler DeepCool AK400 ZERO DARK PLUS — 120 mm FDB fan, 4 heat pipes 6 mm, for LGA 1700/AM4/AM5, height 155 mm, black

The DeepCool AK400 ZERO DARK PLUS is an all-black CPU cooler with a four heat pipe tower and a matrix fin array, equipped with two FDB fans for effective heat dissipation and low noise. The cooler offers up to 220W of dissipation efficiency and a compact form factor suitable for mainstream systems seeking a balance of performance and size.

Advantages

The all-black finish provides a uniform aesthetic for system builds. Four direct-touch copper heat pipes and a single fin-stack tower with a matrix design ensure efficient heat transfer from the CPU. Two fluid dynamic bearing (FDB) fans deliver strong airflow and static pressure when required while reducing speed for quieter operation.

Key specifications

• Heat dissipation efficiency: up to 220W
• Heat pipe type: four direct-touch copper heat pipes
• Radiator: single fin-stack tower with matrix fin design
• Fans: two high-performance FDB fans
• Finish: full black coating
• Compatibility: supports multiple Intel and AMD platforms (modern mainstream CPUs)

How to use

Prepare the motherboard and CPU socket according to the platform instructions, apply thermal paste to the processor surface, position the cooler so the heat pipes contact the CPU, and secure the cooler using the provided all-metal mounting bracket following the five-step installation procedure included in the package. Connect the fan power cables to the appropriate motherboard headers and verify fan operation in BIOS or software.

Recommendations

Ensure case clearance for the tower cooler and confirm RAM and GPU compatibility with the cooler’s height and orientation. Use the included mounting hardware and follow the manufacturer’s installation steps to achieve optimal cooling performance. Regularly check and clean fan blades and fins to maintain airflow and efficiency.
