Coolant Distribution Unit (CDU)

Supermicro CDU contains 1+1 redundant hot-swappable pump systems that circulated the coolant to cold plates cooling down CPUs and GPUs heat. The CDU cooling capacity is up to 100kW enabling extremely high rack densities.

Supermicro Coolant Distribution Unit (CDU)

CPU/GPU Cold Plate

Cold plates are placed on top of CPUs and GPUs to cool down chips efficiently by letting coolant flowing through micro channels in the cold plate.
