DeepCool AK400 Digital SE 120mm ARGB CPU Air Cooler with Digital Display

The DeepCool AK400 Digital SE brings a meaningful upgrade to the proven AK400 series by adding a low-profile real-time status screen and ARGB LED strips, making it a visually expressive yet practically focused single-tower CPU air cooler for mainstream builds. At the heart of this cooler is a digital display that shows live CPU temperature and usage data. When temperatures climb too high, the screen triggers a high-temperature warning so you can act before thermal throttling affects performance. The display is managed through a companion software application that connects to a standard USB 2.0 header on your motherboard — no additional power connector is required. The underlying cooler architecture follows DeepCool’s CTT 2.0 (Contact Thermal Technology) design, featuring four direct-contact heat pipes arranged in a tower layout paired with a matrix fin stack. This configuration improves heat transfer from the CPU integrated heat spreader through the heat pipes and into the fin array, where the bundled FK120 fan dissipates it. That fan uses a Fluid Dynamic Bearing (FDB), a bearing type well regarded for its balance of quiet operation and long-term reliability. Fan speed is PWM-controlled, allowing the system to ramp up under load and step back during lighter tasks for quieter operation. ARGB LED strips run along the cooler body, compatible with standard addressable RGB headers and software from major motherboard vendors, adding ambient lighting that can be synchronised across your system. Compatibility spans a wide range of current and recent platforms. Intel sockets supported include LGA1851, LGA1700, LGA1200, LGA1155, LGA1151, and LGA1150, covering everything from 10th-generation Core processors through to Arrow Lake and Core Ultra series. On the AMD side, AM4 and AM5 are both supported, accommodating Ryzen 3 through Ryzen 9 and Core Ultra 5, 7, and 9 processor lines. Secure mounting hardware is included for all listed platforms, designed to distribute pressure evenly across the CPU lid.
