Claim of US Patent No. 10,893,628

1. A circuit board cooling system comprising:a cooling unit comprising at least two fans configured to generate air flow to cool a portion of a circuit board, the cooling unit configured to operate according to an operating configuration;
a plurality of pressure sensors configured to measure air pressure data at their respective locations, the plurality of pressure sensors comprising:
a first pressure sensor located between the portion of the circuit board and the cooling unit and configured to measure air pressure data at a location of the first pressure sensor; and
a second pressure sensor located such that the portion of the circuit board is between the second pressure sensor and the cooling unit, the second pressure sensor configured to measure air pressure data at a location of the second pressure sensor; and
a sensor processing unit coupled with the plurality of pressure sensors and 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.
