Dell (US) のプレスリリース:

"Dell Leads Shift to "Chiller-Less" Data Centers with Fresh Air Technology"
  "Trends in data center design place an increased emphasis on
   the efficiency and cost benefits that can be achieved with higher
   operational temperatures. In addition to ASHRAE's updated standard,
   The Institute for Energy, a European guidance body, has issued
   the "European Union Code of Conduct for Data Centres," which
   challenges IT manufacturers to increase their allowable environmental
   limits and sets a goal of enabling chiller-less facility designs."

"European Union Code of Conduct for Data Centres," のリンク先
EU Code of Conduct for Data Centres
  "... In line with the new, more stringent ASHRAE A3 and A4 classifications,
   Dell systems have been developed for sustained operation at temperature
   ranges from minus 23 F (5 C) to 113 F (45 C) and allowable humidity
   from 5 percent to 90 percent. This level of design robustness has been
   validated by recent tests indicating that the products can tolerate
   up to 900 hours of 104 F (40 C) operation per year and up to 90 hours
   at 113 F (45 C)"
