In spite of components having different energy densities, all of the components produce some waste heat, so it all has to be dissipated by the cooling system one way or another. In a large datacenter, even the low energy density components (combined across thousands of machines) generate a tremendous amount of heat. Also, it would seem fairly straightforward to design optimized versions of components such as cables to make them better suited for oil, as well as a simple filtration / purity monitoring system.
