69% power converted to computing would be /awesome/ but it is nowhere near, not even close: Only a few tens of kW leave a data center as light and noise, the rest as heat.
Most of the heat is removed by air, the water is used to prevent a heat-pocket from forming over the hot-air exhausts.
Same as power-plant heating towers.
(Yes, very counter-intuitive: Moist air is /lighter/ than dry air.)
