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.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
