Redundant cooling for fluid cooled systems

A fluid cooled system includes a first heat generating component (20a). A first airflow pathway (30a) directs a first flow of air across a first heat exchanger (34a). A second airflow pathway (30b) directs a second flow of air across a second heat exchanger (34b). A first working fluid is flowed from the first heat generating component (20a), through the first heat exchanger (34a) and through the second heat exchanger (34b) and returned to the first heat generating component (20a).
