Why does the thermal performance of laptop is decreased

        Nowadays, notebook computers are exposed in our work, study, life and many times. One of the problems we often encounter in using laptops is heat dissipation. If the heat dissipation effect of notebook computer is not good, the computer will crash, blue screen, and even burn the motherboard. So how to understand and deal with the thermal cooling problem of notebook computers? First of all, we need to understand why laptops are hot.

Four common reasons for laptop cooling difficulties:

1. Ambient temperature is too high:

       Especially in summer, the air temperature rises sharply, and the heat passively dissipated into the air is greatly reduced, while the heat generated by CPU, graphics card and other computer hardware can not be dissipated in time, which leads to the high temperature of notebook computer.

2. Narrow internal space:

     Compared with desktop computers, the advantage of notebook computers lies in 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 a little difficult.

3. Dust accumulation:

     With the service time increase, it is inevitable that dust will appear 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.Thermal grease aging:

     For a long time use, the thermal conductive   grease of CPU and graphics card chip will also affect the thermal performance of notebook, and the thermal conductive copper tube will also be oxidized due to poor heat dissipation, reducing the heat dissipation capacity.

    In addition to a good thermal management system, laptops also need to clean the dust regularly and replace the aging thermal grease,and also need  to avoid long-term high loading operation, so as to ensure the stable performance of the computer and increase the service life.
