The architecture of the AK400 G2 is based on four advanced copper direct touch heat pipes, which efficiently transfer heat to DeepCool's signature matrix fin array. One of the main advantages of its design is the use of offset heat pipes, which shift the heatsink body so that it does not obstruct the RAM slots. This ensures full compatibility even with memory modules that have tall cooling systems, while also allowing an unobstructed view of all internal hardware.

The redesigned fan of the AK400 G2 is equipped with a three-phase motor and high-quality hydraulic bearings, achieving speeds of up to 2200 RPM. It features 0-RPM mode for complete silence under low load, as well as the innovative Activate Clearing (ACT) technology, which, when activated, automatically removes dust from the blades and the fan. Despite generating high static pressure (3.33 mmAq) and an airflow of 63.4 CFM, the cooler keeps noise levels low, offering a powerful yet quiet solution for any modern build.
