Sadly, no. The physics follow though - water has a much higher specific heat than air, so you have to move much less water than air for equivalent cooling. The

Sadly, no. The physics follow though - water has a much higher specific heat than air, so you have to move much less water than air for equivalent cooling. The production of heat by the processors is the same (and you save on air handling electricity/cooling processes, as the water is already cool in the ocean). As for the oceans absorbing the heat, that's how it works anyways - a unit of heat released in the atmosphere has to be sunk somewhere and the ocean is the "Earth's biggest heat bucket".
