As is known to all, high temperature heat is the enemy of the computer not only can lead to system instability, shorten the service life and may even make some parts burned but computers the cause of the high temperature not from outside, but from internal computer in the presence of computer high temperature, the solution is to give computer components with the radiator Most of the radiator is through contact with the surface of the computer accessories, to absorb the heat and then by all means to be distributed to or within the chassis chassis, such as the heat in the air inside the case, then the case will be the hot air to the outside casing, to ensure that the temperature of the computer components at normal temperature, the types of complete computer computer radiator cooling very much, CPU card motherboard chipset drives the on even drive and memory will need radiator, these different radiator is unable to mix the material of radiator with silver copper aluminum, respectively Four types of steel, if the material of radiator comparison to be made with silver to expensive doesn't fit, usually material is copper and aluminum alloy heat sink, but both have the advantages of aluminum material is cheap, but its light weight thermal conductivity is not very good, only five percent of copper copper material though ten prices relatively more expensive, aluminum processing difficulty is higher, the weight is big, but it has good heat conduction performance compared with heat sink copper material is suitable for use
