Abstract
Abstract Methods, systems, and media for thermal analysis are disclosed. Embodiments of the invention receive temperatures associated with elements of a system. The temperatures received are dependant upon airflow and heating patterns of the elements. Differences between the temperatures received and expected temperatures are detected. Potential airflow and heating patterns associated with a thermal problem are then determined, the potential airflow and heating patterns being substantially consistent with the temperatures received, to identify a root cause of the thermal problem as a probable source of the differences. More specifically, embodiments collect temperature readings from temperature sensors within an enclosure of the system; identify and upward temperature gradient or temperature that exceeds a threshold temperature; and select a failure scenario associated with a root cause of a thermal problem that is similar to the thermal problem described by the temperature readings collected.
