How should I apply thermally conductive silicone?

The correct application method of thermally conductive silicone plays a crucial role in reducing the temperature of the CPU/GPU, which can maximize the cooling effect of the CPU.

There is no very standard statement on how to apply thermal silica gel (on the CPU), but those who know a little know that the key to application is uniformity, no bubbles, no impurities, and as thin as possible. We have seen pictures on the Internet showing that the CPU and graphics card are coated with a thick layer. In fact, it is not necessary at all. Everyone knows that the so-called heat conduction means that the heat conduction surface of the CPU is in complete contact with the heat conduction metal sheet of the fan, and the function of thermal conductive silicone is to Fill the tiny gaps between the two contact surfaces. Those who have studied metallography must know that no matter how flat the metal is, it is bumpy under the metallographic microscope. You can go to the hardware store to buy a metallographic sand skin, and grind the fan to conduct heat. The metal sheet can act on the starting point of cooling, and the surface of the cpu and graphics card cannot be ground. Apply thermal conductive silica gel on the surface of the CPU and graphics card, just apply a thin layer and smooth it slightly, you can use a toothpick, then gently put the thermal conductive fan on it, and gently move it up and down several times. Just screw in the screws and it's ok.

Therefore, it is said that applying thermal silica gel is not to win by quantity. If you apply too much, it will push the CPU into the fire pit. Theoretically, under the premise that it can fill the gap between (CPU/GPU) and the surface of the radiator, the thinner the thermally conductive silicone is, the better, because even the best thermally conductive silicone cannot conduct heat better than copper and aluminum. Studies have shown that the thermal conductivity of copper and aluminum is many times stronger than that of silica gel, so the correct coating method should be to ensure that the gap between (CPU/GPU) and the radiator surface can be filled, and the thinner the thermal grease layer, the better. . The correct application method of thermal silica gel plays a crucial role in reducing the temperature of the CPU/GPU, which can make the heat dissipation effect of the CPU optimal.
