How many millimeters of thermally pad is suitable for laptop cooling?

Everyone knows that laptop are generally thicker when they first come out, but with the development of technology, laptop are getting thinner and lighter. Some people will say that because the parts inside become smaller and smaller Lighter, in fact, this is only a small aspect. The main thing is that the components used for heat dissipation are smaller and more effective. The thermal pad can not be separated from it! So, how many millimeters of thickness should be used for the laptop thermal pad?

Before understanding that the laptop thermal pad should use a few millimeters, first make sure that most laptop CPUs still use a fan to dissipate heat, but this fan often also dissipates heat to the host. So most of the thermally pad are used for heat dissipation of the north and south bridge chips. Generally, during installation, a thermally pad will be placed on the two chips of the south bridge and the north bridge, and then the fan heat pipe will be connected above, so that the fan will also improve the heat dissipation efficiency of the thermally pad. However, at present, there are a few laptop that have eliminated the CPU fan and directly used a thermally pad to dissipate heat.

Due to the particularity of notebooks, basically all manufacturers are pursuing lightness and thinness, which requires very high heat dissipation. What should be the thickness of the thermal pad for laptop? In fact, there are no strict rules or standards about how thick it is, but it depends on the laptop itself. If the laptop is thicker, then you can use a thicker one, because the modern manufacturing process has made great progress than before, and the laptop Basically, the thickness requirements can be used between 1-2 mm. Generally speaking, it is very thin, but it also has very high performance requirements for thermally conductive silicone sheets, such as better heat dissipation, shock resistance, and toughness and elasticity. It will not be long-term after long-term use. Great changes have taken place in the thermal environment.
