The top section of AK400 sports plastic top piece which covers the heatpipes and retains a sleek look. This plastic cover features the Deepcool logo and definitely adds appeal to the build.

From this top angle you can see how compact AK400 is with its thin heatsink dimensions (97mm).



Deepcool is using a premium nickel-plated heatsink and a matrix- shaped fin-array for AK400.

Included with this cooler is a single 120mm fan which uses a fluid dynamic bearing. These fans are capable of 500-1850 RPM and airflow of up to 66.47 CFM. Deepcool also provide another set of fan clips to attached a second fan onto the other side of the heatsink.


The baseplate is copper and features direct touch with the four copper heatpipes in a bid to transfer heat away from the processor, dissipating through the fin stack. Deepcool includes pre-applied thermal paste to the cooler and have chosen to use an interesting grid pattern. (No thermal paste is supplied in the accessories bundle).
