CPU Cooler DeepCool AN400 BK Low Profile CPU Cooler

DeepCool AN400 BK is a low profile air cooler for processors, aimed at compact cases, mini-ITX and SFF builds, where height is critical. With a single 92 x 92 x 15 mm fan and a standard 4 PIN connector, it aims for a balance between size, noise, and efficiency. The speed of up to 2950 RPM and static pressure of 4.8 mmAq help the air pass through dense fins even in tight cases. The black color and lack of RGB will appeal if you want a clean, discreet build without a light “circus”.

What you get

You get a low profile cooler designed for compact systems, but with a decent airflow of 31.18 CFM, sufficient for standard gaming and office configurations. The range from 500 to 2950 RPM gives you good control through the motherboard – you can set quieter profiles for idle and more aggressive ones under load. The noise level of 23.2 dBA is low for this class and size of fan, especially when it doesn’t run at maximum constantly. Thanks to support for modern sockets like AM4, AM5, LGA 1700, and LGA 1851, you can comfortably use it in new platforms without worrying about compatibility.

• The cooler features air cooling, which means simple maintenance and lower complexity compared to water solutions – you install it and forget it.
• The supported CPU sockets are AM4, AM5, LGA 1200, LGA 1151, LGA 1150, LGA 1155, LGA 1156, LGA 1700, LGA 1851, so you can use it for both older and current platforms.
• The compact fan size of 92 x 92 x 15 mm is suitable for small cases and low profile configurations, where standard 25 mm fans often collide with RAM or side panels.
• With one included fan (1 pc.) and a 4 PIN connector, you get PWM control through the motherboard and clean installation without excess cables.
• The range of 500–2950 RPM allows flexible fan curve settings – quiet mode under low load and higher airflow during gaming or rendering.
• The airflow of 31.18 CFM is good for this size and helps maintain stable temperatures in a compact system.
• With a noise level of only 23.2 dBA and static pressure of 4.8 mmAq, the cooler is oriented towards quiet but effective cooling of the radiator in limited space.
• Fully black color and without RGB make it suitable for minimalist builds or for cases without windows, where you seek functionality rather than lights.

Who it is suitable for

It is suitable if you are building a compact machine – HTPC, mini-ITX gaming build, or office PC in a small case, where standard towers do not fit. Compatibility with AM5, LGA 1700, and LGA 1851 is a plus if you want a small but current platform. It is not the best choice if you are aiming for maximum overclocking of top high-end CPUs in a large case – there, a larger tower or water cooling would make more sense.

The combination of low profile design, wide socket support, and quiet 92 mm PWM fan makes DeepCool AN400 BK a practical solution for compact and clean configurations where space and noise are a priority.
