A system and method includes at least one heat exchanger, a ram fan (12), and a controller (22). The ram fan is driven by a motor (30). A motor control circuit (18) is configured to provide power to the motor to drive the ram fan. The ram fan is configured to provide a ram flow through the at least one heat exchanger from a ram air inlet (24). The controller is configured to determine a blockage level of the at least one heat exchanger based on the power to the motor, a speed of the ram fan, and a temperature of the ram flow at the ram fan.
