1. A method of identifying faults in an air-cooled system, the air-cooled system including a first temperature sensor configured to detect a temperature of an exhaust heat, a second temperature sensor configured to detect a temperature of a heat sink secured to a heat-generating component, the heat sink having fins, each with a surface area configured to transfer heat to or from air surrounding the heat sink, and an air flow sensor configured to detect a rate of air flow through an air-cooling device, the method comprising: measuring a first series of temperatures with the first temperature sensor to produce a first time series of first measured temperature values; measuring a second series of temperatures with the second temperature sensor to produce a second time series of second measured temperature values; measuring a series of rates of air flow with the air flow sensor to produce a time series of measured air flow rate values; and identifying a fault in response to at least one of: the first time series of the first measured temperature values being outside an acceptable range of a first target value, the second time series of the second measured temperature values being outside an acceptable range of a second target value, and the time series of the measured air flow rate values being outside an acceptable range of a third target value.
