Systems and methods for detecting and analyzing elevated temperatures at a component rack to identify and characterize air recirculation anomalies. In one embodiment, temperatures are sensed in proximity to an air intake of the component rack. Temperature sensors communicate with a workstation having system management software including a thermal management component for analyzing air intake temperatures. Predefined temperature differentials (PTD) are established, corresponding to expected temperature differentials between the selected locations in the absence of any appreciable recirculation. The PTD provides a threshold for comparing with “actual” temperature differentials (ATD) to identify the presence and/or mode of recirculation. If an ATD exceeds a corresponding PTD for a predefined time interval, a signal is output. The mode of recirculation, such as left-side, right-side, or dual-surface recirculation, may be determined using as few as four temperature sensors positioned at a zone of interest (ZOI).
