CPU cooler DeepCool AK400 DIGITAL SE CPU Cooler

DeepCool AK400 DIGITAL SE is an air cooler for CPU, aimed at mid-range configurations where you seek stable temperatures without unnecessary complications. With a single 120 mm fan and a maximum speed of up to 1850 RPM, its goal is to keep your processor cool even under heavier loads. The presence of a 4-pin PWM connector gives you precise control over the RPM and noise. The ARGB and USB 2.0 connectivity also suggest digital extras and lighting that can integrate well with the rest of your system.

What you get
You get air cooling with a 120 x 120 x 25 mm fan, which is the gold standard for most modern cases and airflow configurations. With up to 68.99 CFM (117.21 m³/h) airflow, the cooler can expel a significant amount of warm air from the radiator, helping to maintain lower temperatures during gaming and rendering. The noise level of up to 28 dBA is reasonable for 1850 RPM – you will hear it under full load, but it won't be an annoying “turbine” sound, especially if you set a PWM curve through BIOS or software. The 4-pin connector provides automatic adjustment based on CPU temperature, while the 5V ARGB and 9-pin USB 2.0 give you flexibility for synchronizing lighting and digital functions with other components.

• The cooler is air type, which means easy installation, fewer points of failure, and no worries about liquids or pumps.
• Compatibility with AM4, AM5, LGA 115x, LGA 1200, LGA 1700, and LGA 1851 covers almost all current Intel and AMD platforms, so you can use it even during upgrades.
• The fan size of 120 x 120 x 25 mm is standard, making future replacement or upgrade easier.
• With 1 included fan, you get a balanced profile between efficiency, noise, and simplified installation without complex push-pull configurations.
• Maximum rotation speed of 1850 RPM allows for aggressive cooling when needed, especially during long gaming or rendering sessions.
• Airflow of up to 68.99 CFM (117.21 m³/h) is more than sufficient for mid-range processors and well-ventilated cases.
• Noise level of up to 28 dBA means moderate acoustics that you can easily tame with an appropriate PWM curve.
• The combination of 4 PIN, 5V ARGB, and 9-pin USB 2.0 connectors allows simultaneous control of RPM, lighting, and digital functions through modern motherboards and software.

Who it is suitable for
This cooler is suitable if you are building a mid-range gaming or work machine and are looking for something more meaningful than a boxed cooler, without entering the territory of heavy AIO solutions. It is also a good choice if you want ARGB and digital control but want to stick to classic air cooling. It is not the most logical option if you plan extreme overclocking and maximum quiet operation under full load.

AK400 DIGITAL SE impresses with its combination of wide compatibility, reasonable noise, stable airflow, and modern connectors for lighting and control. If you are looking for a rational yet visually complete cooler for a current platform, this is a very balanced choice.
