Abstract
One embodiment involves detecting the fouling of an air filter used to filter airflow entering a computer system. An expected airflow rate is obtained from a current fan speed. An expected temperature rise between two positions is computed as a function of the expected airflow rate and the power consumption of heat-generating components, such as servers. An actual temperature rise is obtained from temperature sensors. An electronic alert is automatically generated in response to the actual temperature rise exceeding the expected temperature rise by a setpoint. Different setpoints may be used to trigger distinct electronic alerts.
