What is the usual thickness of the thermally conductive silicone sheet for notebooks?

People who have used notebooks will know that notebooks are usually relatively thick when they first come out, but with the development of technology, notebooks are getting thinner and lighter. Some people will say that it is because of the Parts have become smaller and lighter. In fact, this is only a small aspect. The most important thing is that the components used to dissipate heat are smaller and more effective. This is inseparable from the heat-conducting silicone sheet. So, how much thickness should be used for notebook thermal silica gel?

Laptops are different from desktop computers. The mainframe of a desktop computer has a lot of space, and the cooling fan can be directly installed on the chassis and some important components of the motherboard, such as the power supply box, CPU, graphics card, etc. A cooling fan will be installed, and some Desktops even include a fan on the side panel of the case. But for notebooks, the space is limited, and the weight needs to be continuously reduced, so it is impossible to use fans on a large scale. The components that need heat dissipation mainly include CPU, North-South Bridge, graphics card, etc., so if the heat dissipation of your notebook is not good, you can open the back cover and replace the heat-conducting silicone sheet in the corresponding position to improve the heat dissipation effect.

Before knowing how many millimeters should be used for notebook heat-conducting silicone sheets, let’s make it clear that the CPU of most notebooks still relies on fans to dissipate heat, but this fan often also plays a role in dissipating heat from the host. Then the thermally conductive silicone sheet is mostly used for heat dissipation of the north and south bridge chips. Generally, during installation, a heat-conducting silicone sheet will be placed on top of the Southbridge and Northbridge chips, and then a fan cooling pipe will be connected to the top, so that when the fan is running, the heat dissipation efficiency of the silicone sheet will also be improved. However, there are still a small number of notebook computers that have canceled the CPU fan and directly use the CPU thermal silica gel sheet to dissipate heat.

It is precisely because of the particularity of notebooks that basically all manufacturers are pursuing lightness and thinness, which has very high requirements for heat dissipation. How many millimeters should be used for notebook thermal silicone sheets? In fact, there are no strict regulations or standards. How thick it needs to be depends on the notebook itself. If the notebook is thicker, then you can use a thicker one. Because modern manufacturing technology has made great progress compared with before, and the thickness requirements of the notebook itself are basically The thickness that can be used is between 1-2 mm. Generally speaking, it is very thin, but it also has high requirements on the performance of the heat-conducting silicone sheet, such as good heat dissipation, shockproof, toughness and elasticity. great changes in the thermal environment.
