## Summary description

DeepCool AK400 is a 120 mm air cooler for processors featuring four 6 mm copper heat pipes, a 120×25 mm Fluid Dynamic Bearing fan (500–1850 RPM) and maximum airflow of 66.47 CFM with 2.04 mmH2O air pressure. Designed for CPU cooling on multiple sockets (including LGA 1150/1200/1700 and AM4/AM5). Compact radiator (127×97×152 mm approx.), low noise (29 dB) and straightforward mounting with included bracket and screws.

## Long description

The DeepCool AK400 is a performance CPU cooler with a classic four heat-pipe tower layout, a matrix fin array and a high-performance FDB fan. It delivers effective heat dissipation up to 220W TDP for mainstream desktop systems while maintaining very low noise levels, and is compatible with current Intel and AMD sockets.
Advantages
The AK400 offers strong cooling efficiency for its size thanks to four direct-contact copper heat pipes and a dense fin stack. The fluid dynamic bearing (FDB) fan provides balanced airflow and static pressure when required, while operating quietly during light load. The cooler uses an all-metal mounting bracket and a simplified five-step installation process for secure mounting across multiple platforms.
Key specifications
Cooling type: Tower air cooler with four direct-touch copper heat pipes
Fan: High-performance FDB fan delivering high airflow and low noise
Cooling capacity: Up to 220W (TDP)
Fin design: Matrix fin array for improved heat dissipation
Compatibility: Supports modern Intel and AMD sockets (multi-platform)
Mounting: All-metal mounting bracket with simplified five-step installation
How to use
Prepare the motherboard by applying the appropriate thermal paste on the CPU heat-spreader. Attach the all-metal mounting bracket following the included instructions for your socket, position the AK400 so the heat pipes contact the CPU directly, then secure the cooler using the five-step fastening procedure. Connect the fan to the CPU\_FAN or PUMP\_FAN header and verify fan operation in BIOS or monitoring software before closing the case.
Recommendations
For optimal results, ensure good case airflow with at least one intake and one exhaust fan. Reapply thermal paste after removing the cooler for maintenance and confirm RAM clearance if using tall memory modules.
