The function of thermally conductive silicone


The purpose of thermal conductive silicone is to cover the gap between the CPU and the heat sink and to transfer the heat. It is only in the past that the thermal value of the CPU was not large and the total area of the key was large that we ignored the efficacy of the thermal conductive silicone. Today's CPU, especially AMD series products, if you do not pay attention to the problem of thermal paste is very easy to produce damage to the CPU risk. There are two kinds of thermal paste on the market today, canned and tube-mounted. Generally speaking, tube-mounted is good, as the canned thermal paste has a layer of sticky silicone rubber on it, it is difficult to separate it from the thermal paste underneath, which will affect the CPU heat dissipation afterwards.

In addition, there are many enthusiasts who use special thermal pastes in order to give the cooler a better heat transfer performance. The genuine INTEL thermal paste is dark grey in colour, which is due to the higher heat transfer performance of the graphite powder. Only this kind of thermal paste is not very good to buy, the most common or general cream thermal paste on the market at present. However, you can also make your own special thermal paste by using the usual milky white thermal silicone and a pencil lead of 2B or more as raw material. The method is very simple is to put the pencil lead into the milky white thermal conductive silica gel grinding, grinding and thermal conductive silicon mix, such as grinding bad after a certain level, the thermal paste will turn black and grey, then high purity graphite thermal conductive silica gel is made. But to pay attention to one point, in the whole process of making to pay attention to the strength of the grinding pencil, or pencil core particles are very large in turn will affect the actual effect of heat transfer. The same principle of putting creamy heat dissipation paste into the middle of two pieces of aluminium rubbing can also be made of aluminium heat-conducting silicone. In addition, the guys can also try to make their own preservatives for other raw materials, such as tin, copper, etc.
