Report: Most data centers are too cold
Even though ASHRAE recommends that data centers maintain 80 F temperatures, 100% of respondents cooled their facilities to 74 F or less.
Representatives from Intel , IBM , Hewlett-Packard , Liebert Precision Cooling , and Lawrence Berkeley National Lab conducted the study, along with a recent Liebert survey of members of the Data Center Users Group ( DCUG ), that showed that 100% of respondents was cooling data centers significantly below ASHRAE 's recommended 80.6 F.
Last year, ASHRAE raised its 2004 high-end recommendation for inflow temperature from 77 F to 80.6 F. Of the 98 respondents to the DCUG survey, however, none had a computer-room air handling inflow temperature higher than 74 F, and the majority chilled their air to 70 F or below.
Chilling the air, of course, requires a significant power outlay, but getting the servers to communicate their cooling needs to computer-room air conditioning (CRAC) units is difficult because the equipment works on different protocols. Additionally, CRAC-unit vendors aren't motivated to step up and say that overly cool data centers are wasting power and money, since they profit from selling more powerful cooling systems.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
