DEEPCOOL AN400 Single Tower 92mm CPU Air Cooler ( Black )

The Deepcool AN400 is a single-tower, top-down low-profile CPU air cooler designed for builders who need effective thermal management without sacrificing clearance inside compact or ITX cases. Measuring just 92 × 92 × 52.5 mm overall, it fits in environments where taller tower coolers simply cannot, while still delivering a rated thermal design power of 150W — making it suitable for a broad range of mainstream desktop processors. The AN400's top-down airflow orientation does more than cool the CPU: it simultaneously delivers passive airflow across the VRM components surrounding the CPU socket, which can benefit overall motherboard longevity in tightly packed builds. The heatsink itself (94 × 57 × 38 mm) incorporates 62 nickel-plated aluminium fins, four optimised 6 mm copper heatpipes, and a raised copper cold plate for efficient heat transfer from the CPU die to the fin stack. Propelling air through the assembly is a 92 × 92 × 15 mm Fluid Dynamic Bearing (FDB) fan. Driven by a visible 3-phase 6-slot 4-pole motor and connected via a 4-pin PWM header, the fan scales smoothly between 500 and 2,950 RPM (±10%), delivering up to 31.18 CFM of airflow at up to 4.8 mmAq static pressure — all while keeping acoustics at or below 23.2 dB(A). White LED lighting adds a subtle visual accent. Installation is aided by an all-metal backplate that distributes mounting pressure evenly across the rear of the motherboard. Socket compatibility covers a wide range of current and recent platforms, making it a versatile upgrade or new-build option.
