Seymour Cray referred to himself as an "overpaid plumber" for good reason. Heat management has been a critical element of high performance computing for a long time

If I recall, one iteration of their products sprayed a shower of cooled liquid Fluorinert[1] directly into the processor cards, with no heatsinks at all. [2]

It was fully immersed! The Fluorinert was circulated through the stacked cards, then re-chilled with a cold water heat exchanger.
