We are in Seattle and use an air-exchanger system that relies on outside air as much as possible, and then blends in chilled water as necessary up to 100% chilled. It's fairly common here because of the nature of our climate, and the psychrometric scale (http://en.wikipedia.org/wiki/Psychrometrics) is favorable for us. We've also looked at increasing our data center temps from 68F/20C to closer to 78F/25.56C (hi Gert), but our marketing folks have been the most resistant because of the prevailing expectation that colder is better. There is some good research and testing being done by Microsoft, Intel and Google in this arena, but I don't think enough has been published yet to give that calming feeling to the marketing folks. I would imagine, however, that we will see increasing data center temperatures more and more in the coming years.
