What is the use of side blown cooling fan

Some CPUs with a side-blown cooling fan, installed in the ordinary vertical chassis, it should be the heat from the CPU to guide the chassis fan, that is, the rear of the chassis fan, and then the chassis fan will be directly pumped hot air to the outside of the chassis, so that the installation of the cooling effect is obvious

In use, many users are accustomed to open the chassis, so that the internal cooling of the machine better. Actually do not know, the inside of the chassis has relatively strong electromagnetic radiation, long-term so will cause damage to the body. Therefore, the chassis has a cooling problem, it is best to take the installation of fans, such as improving hardware cooling measures, do not open the chassis cover heat.
