DeepCool AK400

A straightforward tower for a build that does not need to revolve around its cooler.

The decision

The AK400 keeps the choice focused on a single 120 mm fan and a 155 mm tower. Shortlist it when replacing a basic cooler or finishing a mainstream build; judge the result against your actual CPU power limits and case airflow, rather than treating four heatpipes as a guaranteed cooling capacity.

Consider it when

  • A conventional tower case with enough room above the CPU.
  • A simple PWM-controlled air-cooling layout without pump or display wiring.

Look again when

  • A small enclosure with less than 155 mm cooler space.
  • A sustained high-power workload without evidence that this exact CPU and cooler pairing meets your target.

THE SPACE IT NEEDS

Check the height with the fan installed

Confirm the manufacturer fan position, RAM clearance and the case side-panel limit. The drawing does not measure cooling performance.

The checks that can change your choice

Check the whole 127 × 97 mm footprint

Height alone does not describe fit. Compare the tower and fan position with memory, nearby motherboard heatsinks and the path to the rear case fan before deciding the installation is clear.

Match the mounting kit to the box

The current multi-socket product page is broader than some older packaging. Confirm that the retail box includes the bracket for your CPU socket, especially when buying older stock.

A different choice worth checking

Thermalright Assassin X 120 Refined SEThe Assassin X 120 Refined SE is worth considering before committing a compact tower to a larger dual-tower cooler. Its published 148 mm heatsink gives a different fit envelope from Thermalright models with similar names. Keep the selection tied to the exact Refined SE and the CPU workload you intend to sustain.Read this model’s tradeoffs ↗Noctua NH-U12S reduxThe NH-U12S redux makes sense when accessible memory and a relatively narrow cooler are more useful than filling the socket area. Its single NF-P12 redux fan also keeps the initial wiring simple. Decide on the 158 mm installed height and exact motherboard compatibility before assuming it will fit any ordinary ATX case.Read this model’s tradeoffs ↗
