Wind pressure and air volume are two relative concepts. Generally speaking, in the consideration of cost-saving by the manufacturer, to design a fan with a large air volume, some air pressure must be sacrificed. If the fan can drive a lot of air flow, but the wind pressure is small, the wind cannot blow to the bottom of the radiator (this is why some fans have high speed and large air volume, but the heat dissipation effect is not good). On the contrary, High wind pressure often means that the air volume is small, and there is not enough cold air to exchange heat with the heat sink, which will also cause poor heat dissipation.
