Changes in equipment cooling performance may be detected by indirectly measuring cooling performance by way of a cooling efficiency indicator. An operating cooling efficiency indicator is calculated as a ratio between equipment electrical power consumption and a temperature differential between the equipment and an ambient temperature. The operating cooling efficiency indicator is compared to a baseline cooling efficiency indicator to detect changes in cooling performance.
