1. A datacenter cooling system, comprising:
a plurality of parallel refrigerant paths associated with one or more flow controllers, the one or more flow controllers to distribute refrigerant to cold plates along the plurality of parallel refrigerant paths such that each of the plurality of parallel refrigerant paths receive equal ratios of a liquid phase of the refrigerant relative to a vapor phase of the refrigerant based in part on a cooling requirement of at least one of a plurality of computing devices, the cold plates to cool the plurality of computing devices.
