A thermal management system for cooling a computing device includes a cold aisle, a hot aisle, a radiator, and a plurality of source heat sinks thermally conductively connected to the radiator. The radiator connects the cold aisle to the hot aisle and flows a cooling fluid through an interior volume of the radiator. Each source heat sink is configured to connect to a heat-generating electronic component to thermally conductively connect the heat-generating component to a surface of the radiator.
