The latest company to focus attention on temperature in the data center is Google. “The guidance we give to data center operators is to raise the thermostat,” said Erik Teetzel, an Energy Program Manager at Google. “Many data centers operate at 70 degrees or below. We’d recommend looking at going to 80 degrees.”

Data center managers can save 4 percent in energy costs for every degree of upward change in the set point, according to Mark Monroe of Sun Microsystems, who discussed data center set points at a conference last year.
The article covers different approaches and some of the downsides that balance the upside potential. Worth a read.
Intel recently conducted a 10-month test to evaluate the impact of using only outside air (also known as air-side economization) to cool a high-density data center in New Mexico, where the temperature ranged from 64 degrees to as high as 92 degrees. Intel said it found “no consistent increase” in failure rates due to the greater variation in temperature and humidity.
I’m hearing more and more HPC centers are trying this. Are you? What’s your experience? There are evidently real benefits
