DeepCool AN400 Low-Profile Top-Flow CPU Air Cooler

Low-Profile Top-Flow Cooling for a Compact Desktop Plan

The DeepCool AN400 is a low-profile CPU air cooler with four 6 mm heatpipes and a slim 92 mm PWM fan. Its top-down layout is relevant to compact desktop builds where a tall tower or radiator is not the preferred fit, while the silver heatsink and white LED detail keep the appearance restrained.

With a published 52.5 mm overall height, this cooler still needs an exact case, motherboard and CPU compatibility check. Compact cooling is a balancing act: airflow, processor power behaviour and sustained workloads affect the result, so do not treat a small footprint or a design rating as a guaranteed temperature for every processor.

Best For: Compact desktop builds, Compatible Mini-ITX layouts, Low-height cooling plans, Top-flow air cooling, Non-ARGB styling, Space-conscious upgrades

DETAIL SPECIFICATION

TECHNICAL FEATURES

Cooling directed toward the motherboard

The top-down fan pushes air through the compact heatsink toward the socket area. The airflow path remains dependent on a ventilated enclosure and should be considered alongside the case intake and exhaust.

A slim PWM fan

The 92 × 92 × 15 mm fan supports PWM control over its specified speed range. Fan curves and noise in the finished PC depend on the motherboard settings and cooling demand.

Four heatpipes in a low-height assembly

Four 6 mm heatpipes connect the cooling assembly within a low-profile layout. Check the full installation envelope and nearby components rather than assuming all Mini-ITX systems have the same clearances.

A focused lighting choice

This AN400 specification lists white LED lighting, not a programmable ARGB feature set. Select the exact model and appearance intended for the build.

🔎 Technical Conclusion

Cooling Design:
A four-heatpipe low-profile top-flow air cooler, not a tower or liquid-cooling radiator.

Socket Compatibility:
Officially listed for Intel LGA1851/1700/1200/1151/1150/1155 and AMD AM5/AM4; follow the correct mounting procedure.

Fan Control:
A slim 92 mm, 4-pin PWM fan with Fluid Dynamic Bearing for speed control through compatible hardware.

Physical Fit:
Published overall height is 52.5 mm; confirm all case and surrounding-component clearance before ordering.

Installation Planning:
Match the socket, mounting method, fan connection and processor cooling demand within a ventilated enclosure.

Overall Positioning:
A compact-build cooling option where low height is important, with no promise of a universal CPU temperature or silent operation.

✅ Suitable For

• Compact-PC builders
  Use it when the exact enclosure and motherboard layout support the cooler and its installation hardware.
• Owners replacing a compatible low-profile cooler
  Check the processor’s sustained cooling demand and available space before selecting a replacement.
• Builders preferring top-flow air cooling
  The downward airflow layout can fit a different component arrangement from a tall tower, but still needs a planned case airflow path.
• Users wanting simple white-LED styling
  The specified white LED suits a restrained build without representing the product as an ARGB cooler.
