DeepCool AK400 Single Tower CPU Air Cooler (Black)

The DeepCool AK400 Single Tower CPU Air Cooler in Black is a capable and compact cooling solution built for mainstream desktop systems demanding reliable thermal management without excessive noise. Its classic single-tower configuration houses a stack of aluminium fins arranged in a distinctive matrix array design, allowing airflow to move efficiently through the heatsink structure and carry heat away from the CPU rapidly. At the heart of the AK400's thermal performance are four direct-contact copper heat pipes, each measuring 6 mm in diameter. These pipes draw heat directly from the processor integrated heat spreader and channel it upward into the fin stack, enabling the cooler to handle up to 220W of heat dissipation — a figure that covers the thermal demands of most mainstream Intel and AMD processors. Cooling the fin stack is a 120 mm Fluid Dynamic Bearing (FDB) fan. FDB technology reduces internal friction compared to sleeve-bearing alternatives, contributing to both a longer operational lifespan and quieter running. The fan operates across a speed range of 500 to 1850 RPM (±10%), delivering up to 66.47 CFM of airflow and 2.04 mmAq of static pressure. At peak load the fan remains at or below 29 dB(A), keeping the system acoustically unobtrusive. The 4-pin PWM connector allows the motherboard to intelligently regulate fan speed based on real-time temperature readings. Socket compatibility spans Intel LGA1700, LGA1200, LGA1151, LGA1150, and LGA1155 platforms, as well as AMD AM4. Installation is facilitated by an all-metal mounting bracket designed for a straightforward five-step process, reducing the effort required to seat and secure the cooler correctly. The cooler measures 127 × 97 × 155 mm overall (heatsink: 120 × 45 × 152 mm) and has a net weight of 661 g, making it suitable for most standard ATX and Micro-ATX cases with adequate CPU cooler clearance.
