Abstract
Predictive monitoring of computer cooling systems includes generating, at a computer system, a model representative of at least a relationship between a rotational speed of one or more fans configured to cool computing components and a duty cycle of the pulse-width modulation of electrical current supplied to the one or more fans. The computer system determines a first effective range for the rotational speed of the one or more fans as a function of the duty cycle based on the model and monitors data representative of the rotational speed of the one or more fans and data representative of the duty cycle. The computer system generates a predictive failure alert when the data representative of the rotational speed indicates that the rotational speed is outside of the first effective range for a particular value of the duty cycle.
