In general, an ambient temperature range in the data center of 70° to 74° F (21° to 23° C) is optimal for system reliability and operator comfort. Most computer equipment can operate within a wide psychrometric range, but a temperature level near 72° F (22° C) is best because it is easier to maintain safe associated relative humidity levels. Standards for individual manufacturers and components vary, so check the manufacturer's specifications for appropriate temperature ranges.

Another reason for keeping the temperature ranges maintained as close to the optimal temperature as possible is to give the greatest buffer against problems and activities that can change the temperature profile. Following are some possible causes ...
