In at least one embodiment, flow controllers 278 may be associated with a fluid inlet 276 and outlet portions at a server manifold 204 instead of provided flow controllers 280 at respective cold plates. In at least one embodiment, a first flow uses only two-phase fluid and may be enabled when a failure is determined in a secondary cooling loop or a primary cooling loop, so that a secondary coolant is unable to effectively absorb heat from at least one computing device. In at least one embodiment, a failure may be that a secondary coolant is not sufficiently cooled via a CDU and so it may be unable to absorb sufficient heat of at least one computing device via its associated cold plate.
