For CPU cooler for cooling fin area and density row determines the cooling effect, of course, there is also inseparable from "24V DC Cooling Fan". It is behind the fan and cooling fins row, so they need big pressure of "24V DC Cooling Fan" penetrate, in order to better heat away. The rear of the front panel of the chassis fan is responsible for providing the cold air inside the chassis. Most chassis panel consisting of at least one surf the web baffle design, and the fan behind the hard drive cage position. It requires a large pressure type of "24V DC Cooling Fan" can blow through the front of the chassis, which will inject a steady stream of cold air inside the chassis.
