Deepcool AK400 Black CPU Air Cooler

The DEEPCOOL AK400 Black is a single-tower CPU air cooler built around four direct-touch copper heat pipes and a 120 mm Fluid Dynamic Bearing (FDB) fan. It is designed to keep mainstream Intel and AMD processors running cool without introducing distracting noise into your workspace. The four ø6 mm direct-contact copper heat pipes are arranged in a classic tower layout and channel heat rapidly away from the CPU heat spreader into a single fin stack with a matrix array fin design. The matrix pattern creates turbulence within the airflow path, promoting more efficient heat transfer across the aluminium fin surface area. The bundled 120×120×25 mm FDB fan operates between 500 and 1850 RPM (±10%) via a 4-pin PWM connector, letting your motherboard automatically scale fan speed to thermal load. At full speed it delivers up to 66.47 CFM of airflow at 2.04 mmAq static pressure, while the Fluid Dynamic Bearing design keeps audible noise at or below 29 dB(A) — noticeably quieter than many competing coolers in this class. The fan draws 1.56 W at 12 VDC with a rated current of 0.13 A, so it adds minimal load to your PSU’s 12 V rail. Installation uses an all-metal mounting bracket and a five-step process covering Intel LGA1700, LGA1200, LGA1151, LGA1150, and LGA1155 sockets, as well as AMD AM4 and AM5. The cooler ships with mounting hardware for all supported platforms, so no additional bracket purchase is required for current-generation builds. At 661 g and overall dimensions of 127×97×155 mm (heatsink: 120×45×152 mm), the AK400 fits inside most mid-tower and many compact mid-tower cases. Its 155 mm total height is a common clearance reference when checking case compatibility. A 3-year manufacturer warranty covers this unit.
