Electronic thermal grease, which is a thick gray paste with a strange smell applied to the CPU. It is used to fill the gap between the CPU and the heat sink, conduct the heat emitted by the CPU to the heat sink, and keep the CPU temperature at One can stabilize the working level, prevent the CPU from being damaged due to poor heat dissipation, and prolong the service life of electrical components.
The role of thermal grease, silicone grease is essential
Many heat sinks cannot fit the CPU perfectly. Most of them are concave inward or convex outward, so there is a considerable area between the heat sink and the processor without direct contact. In addition, even if your CPU top cover or the bottom surface of the radiator looks very smooth and can even reflect light, they are still a lot rougher than you think at the microscopic level. Therefore, they will not fit each other perfectly, which means that without silicone grease, there will be many small air pockets between the CPU and the heat sink. Air is actually a poor thermal conductor, and silicone grease will fill the original The air gap between the radiator and the CPU can fit more closely.
How to use silicone grease correctly
The correct application of thermal grease directly affects the heat dissipation performance of the CPU. The main function of thermal grease is to fill the gap between the CPU and the heat sink. The thicker the application, the better, the thicker the application, the worse the thermal conductivity, and the effect of air bubbles. Thermal performance.
When applying silicone grease, you can move clockwise and counterclockwise to ensure that the silicone grease fills up the risk and unevenness at the bottom of the radiator. Be careful not to apply it directly with your hands! Apply evenly. For the bottom surface of a common radiator, the thickness of the silicone grease is about the thickness of a piece of paper. After the silicone grease is applied, place the heat sink on the CPU. At this time, you can only press it lightly, and cannot rotate or translate the heat sink. Otherwise, the thickness of the silicone grease between the heat sink and the CPU may be uneven. In theory. On the premise of ensuring that the gap between the CPU and the radiator surface can be filled, the thinner the thermally conductive silicone grease layer is, the better. After all, in terms of thermal conductivity, no matter how good the silicone grease is, it can't compare to copper and aluminum. Most common silicone greases will "dry" or "harden" after being used for half a year or longer. Therefore, to keep the system running stably for a long time, it is necessary to clean and reapply the silicone grease regularly.
