Introduction to the difference between thermal conductive silica gel sheet and thermal conductive grease

Thermal conductive silica gel sheet and thermal conductive grease can be used to assist CPU heat dissipation, so that the CPU heat dissipation system capacity as much as possible to increase, so what is the difference between the two, Shenzhen Liantengda Technology Co., Ltd. for you to compare one by one, so that you can choose more suitable for their own thermal conductivity materials.

Generally, it is not convenient to apply thermal grease, such as the power supply part of the motherboard. Now the heat supply part of the motherboard is generally large, but the MOS tube part is not smooth, so it is not convenient to apply thermal grease. In this case, thermal conductive silica gel sheet is the best choice. Secondly, the heat sink of the graphics card needs multiple parts and different parts of the graphics card contact, in this case, can only use thermal conductive silica gel sheet. We still recommend the use of thermal grease on ordinary desktop CPU, because compared with hardware, these parts are more disassembled and assembled, and the use of thermal grease is convenient for future disassembly and installation of other operations.

Other differences:

1. Insulation: Because of its fluidity and the addition of metal powder, thermal conductive silicone grease has poor insulation performance. Thermal conductive silicone sheet has good insulation performance, and the electrical insulation index of 1mm thickness is above 4000 volts.

2. Form: thermal conductive silicone grease for paste, thermal conductive silicone sheet for sheet.

3. Usage: The thermal conductive silicone grease needs to be carefully smearing evenly, which is easy to dirty the surrounding devices and cause short circuit and damage the electronic components. The thermal conductive silicone sheet can be arbitrarily cut into different shapes and sizes, and the protective film can be torn off and used directly, with small tolerance and clean.

4. Thickness: thermal conductive silicone grease can not fill the gap, the thickness of thermal conductive silicone sheet varies from 0.3mm-10mm, can fill the gap, so the thermal conductive silicone sheet is relatively widely used.

5. Thermal conductivity effect: the thermal conductivity of thermal grease is better than that of thermal conductive silica gel sheet under the same thermal conductivity coefficient, because the thermal resistance of thermal conductive silicone grease is smaller

6. Convenience of disassembly and assembly: It is convenient to reinstall the thermal conductive silicone sheet, and it is not convenient to reapply the thermal conductive grease after disassembly.
