why does the laptop computer over heating

          Nowadays, notebook computers are exposed in our work, study, life and many times. We often encounter such a problem in use, that is, the heat dissipation of notebook computers. If the heat dissipation effect of notebook computer is not good, the computer will crash, the blue screen, and even burn out the motherboard. So how to understand and deal with the heat dissipation of notebook computers? First of all, we need to understand why laptop computers are hot.

There are four common reasons for laptop computer cooling difficulties:

1. The ambient temperature is too high: especially in summer, the air temperature rises sharply, and the passive heat dissipation into the air is greatly reduced. However, the heat generated by CPU, graphics card and other computer hardware cannot be released in time, which leads to the high temperature of notebook computers.

2. Narrow internal space: compared with desktop computers, notebook computers have the advantage of convenience. Because of this, the internal space of notebook computers is relatively narrow, and large-scale heat dissipation devices cannot be installed like desktop computers, so heat dissipation will be somewhat difficult.

3. Dust accumulation: with the growth of service time, it is inevitable that there is dust inside the laptop, but a large amount of dust will isolate part of the heat emission. In addition, the laptop has been used for more than 2 years, and the excessive accumulation of grease in the exhaust fan will also lead to the decrease of fan rotation speed.

4. Aging of thermal conductive silicone grease: after long time used, thermal grease of CPU and graphics card chip will also affect the heat dissipation of notebook, and thermal conductive copper tube will also be oxidized due to poor heat dissipation, reducing the heat dissipation capacity.
