Dimensions and Curves (unit: mm)DC Cooling Fan InterfaceTips: What is the air volume and air pressure of the cooling fan?The cooling fan air volume refers to the total volume of air sent or drawn by the fan per minute. The unit of air volume often used in fan products is CFM, which is Cubic Feet per Minute.When the materials are the same and the heat dissipation principle is the same, the air volume is the most important index to measure the heat dissipation capacity. Simply put, a fan with a larger air volume has a higher heat dissipation capacity. This is because the heat capacity of air is constant, and the larger the air volume, that is, the more air can take away more heat per unit time. The air pressure of a cooling fan is also called static pressure, which refers to the difference in air pressure between the fan's air inlet and air outlet. Usually, the unit is millimeter of water column height (mmH2O) or inch of water column height (inchH2O).
