You can get better cooling performance at the cost of slight water usage or you can use more energy without using water at all.
The greener solution is to use water.

  Seems like it'd depend a lot on e.g. carbon impact of the marginal watt v.s. environmental impact of the marginal gallon? Might depend on the individual site.

    Is there much impact of a marginal gallon? This is evaporative cooling, no? It's gonna come back down as rain and refill wherever datacenter took it from.

    It's going to come back down as rain, yes, but there is no guarantee it will come down in the place you need it. Fairly minor variations in surface temperatures and evaporation can have a large effect on local rainfall.
