In at least one embodiment, spent second coolant exchanges its heat with a primary coolant in a primary cooling loop 106 via a CDU 112. In at least one embodiment, spent second coolant may be renewed (such as relatively cooled when compared to a temperature at a spent second coolant stage) and ready to be cycled back to through a second cooling loop 108 to one or more computing components. In at least one embodiment, various flow and temperature control features in a CDU 112 enable control of heat exchanged from spent second coolant or flow of second coolant in and out of a CDU 112. In at least one embodiment, a CDU 112 may be also able to control a flow of primary coolant in primary cooling loop 106.
In at least one embodiment, server-level features 200 as illustrated in
