The high temperature of the system is easy to cause an unstable computer operation, but also a serious cause a crash or reboot, or even damage the hardware, then good heat dissipation is essential, if the fan heat poor, they should immediately be processed. The poor fan cooling Usually increased dust caused by lack of lubrication. Cooling fan in hardware cooling at the same time, will also have the side effects of the inhalation of dust and more dust not only hinder the cooling of the heat sink, will also affect the rotation of the fan, the fan is in use for some time to be cleaned.
