DC Cooling Fan InterfaceTips: How to install a cooling fan in the case?The installation of the cooling fan in the chassis depends on the airflow in the heat source distribution area of the chassis. Generally, the cooling fan in the chassis is installed on the front side of the chassis. It draws strong cold air from the front side and blows it to the motherboard. Finally, the switching power supply cools the wind and the fan row Come out and produce convection.It is best to consider the orientation of the gas fluidity. The best plan is to install a cooling fan on the front and back, in a diagonal orientation distribution area, and then the heat dissipation effect of all the cases is very good. The front fan of the case blows inside and the rear fan Blow to the outside. As one of the most important links in computer peripherals, the choice of switching power supply can be said to be crucial.
