Abstract: A circuit board cooling system includes a circuit board with a processor disposed thereon, a cooling unit operating according to an operating configuration to generate air flow to cool a portion of the circuit board, and a plurality of pressure sensors that are coupled with a sensor processing unit and configured to measure air pressure data at their respective locations. The pressure sensors include a first pressure sensor located between the processor and the cooling unit and a second pressure sensor located such that the processor is between the second pressure sensor and the cooling unit. Air pressure data measured by the plurality of pressure sensors is obtained by the sensor processing unit. The sensor processing unit compares the obtained air pressure data to reference air pressure data for the operating configuration and, based on the comparison, determines that a disturbance to the air flow exists.

Abstract: A circuit board cooling system comprises a cooling unit comprising fans, pressures sensors that measure air pressure at their locations, and a sensor processing unit coupled with the pressure sensors. The cooling unit operates according to an operating configuration and generates air flow to cool a portion of a circuit board. The pressure sensors comprise a first pressure sensor located between the portion of the circuit board and the cooling unit; and a second pressure sensor located such that the portion of the circuit board is between the second pressure sensor and the cooling unit. A sensor processing unit is configured to: obtain the air pressure data measured by the plurality of pressure sensors; and adjust the operating configuration of the cooling unit based on a cooling specification and a comparison of the obtained air pressure data measured by the first pressure sensor and the second pressure sensor.
