Abstract
An air pressure drop detecting device for detecting air flow volume of a cooling fan includes a first pressure sensor, a second pressure sensor, and a display unit. The cooling fan has an air inlet and an air outlet opposite to the air inlet. The first pressure sensor is positioned in the air inlet and detects a plurality of first pressure values. The second pressure sensor is positioned in the air outlet and detects a plurality of second pressure values. The display unit is connected to the first pressure sensor and the second pressure sensor to display the first pressure values and the second pressure values, and a position of the cooling fan in the computer case is determined by the pressure difference between the first pressure values and the second pressure values.
