How do you solve the problem of air volume, wind pressure and wind power of the cooling fan

For the existing cooling fan, if the heat dissipation capacity is not enough, it may be that the air volume/wind pressure/wind force is not enough, what should be done? Is there any way to + the air volume/wind pressure/wind force of the large cooling fan? The following directions are for your reference: 1. Increase the speed of the cooling fan, and the speed will increase, the air volume/wind pressure/wind force will increase, mainly from + thick silicon steel sheet, increase the power of the motor, or change it to 3-phase Motor and other programs. 2. Without changing the length and width dimensions of the heat dissipation fan, + large thickness, such as the original 40*40*10mm, change it to 40*40*28mm; or when the thickness does not change, + large length and width, such as It was originally 40*40*10mm, but changed to 50*50*10mm. These two methods both make the leaf area larger, and the air volume/wind pressure/wind force will become larger to varying degrees.
