Interesting article; I know we're being conscious about energy/costs/etc. but the new Nikhef PDP data center is pretty cold, at least the inlet is way below 25degC.
Intel wants you to know that data centers are wasting energy - and money - by over-cooling their servers, burdened by warranties that may prevent them from aggressively raising their temperature.
