CPU can be said that the mastermind of the computer, it is the same as the human brain, commanding the various parts of the computer at the same time, therefore, in the summer comes, people will be more attention to the computer CPU, computer CPU temperature High fever motherboard, making the computer blue screen, crash, Caton and other phenomena is not uncommon. So in every computer design there will be a CPU fan to CPU cooling.
   
 CPU temperature is generally too high heat is not in place. There are several major reasons for the cooling problem.
 First, the installation, installation is not standardized, too much or too little silicone, cpu and cpu fan is not close. Poor contact with the thermal surface is also common. Unloaded to check it, that is able to see cpu Ye Hao observation cpu and cooling rack contact. Replace with a good silver-containing thermal grease.

Second, CPU fan quality problems, fan damage, fan aging, stop to turn. Will cause insufficient cooling capacity to promote the CPU temperature is too high.

Third, the CPU fan on the backlog too much dust, fan bearing oil, making the CPU fan rotation is difficult, lower speed, resulting in heat dissipation is not in place.

Fourth, the computer viruses Trojans, Sasser virus and some spyware, etc., can also cause the boot CPU to use the same problem.
     
Cooling method:
First, clean the dust inside the case (the correct way is to use a bicycle pump blowing dust).

Second, in the CPU and the heat sink must be added between the thermal grease. And to smooth.

Third, in the cooling fan bearing drip drip sewing oil, which can effectively reduce the noise! Do not drop more, a drop on the line.

Fourth, the installation of high-power CPU fan, replace a better CPU fan.

Fifth, install the chassis cooling fan (must buy double ball bearing).

Sixth, the host moved to a good vents
