This article introduces the relevant knowledge of "what are the methods of laptop-assisted heat dissipation". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Base radiator:

The principle of the base radiator is to raise the bottom surface and blow the bottom air inlet through the built-in fan of the radiator to actively increase the air intake volume and strengthen the air duct circulation. In the test, we bought two products, one is the most common iron grid panel, built-in 6 small caliber fans, the other is aluminum perforated panel, built-in two large-caliber fans. From the actual test results, the two products have a certain heat dissipation effect, the core temperature of CPU and GPU has dropped to less than 90 ℃, and the surface temperature has also decreased slightly. On the other hand, the effect of aluminum panel and large diameter fan is better, the core temperature is reduced by about 10 ℃, and the surface temperature is reduced by about 4 ℃.

On the whole, although the effect of the base radiator is not particularly strong, it still has a certain heat dissipation effect, with an average core temperature of 5 ℃ to 10 ℃, and a drop of surface temperature within 5 ℃, which is suitable for models with a certain heat dissipation pressure, but the pressure is not particularly large. In addition, if there is no air inlet on the bottom of the notebook, its function is also very limited.

In addition, from the test just now, we can see two problems in the selection and purchase. The first one is not that the more fans, the better. We should pay attention to the parameter of air volume when choosing and purchasing. This is the most important point. Second, the thermal conductivity of the aluminum noodle version is better than the common iron mesh, but the price is more expensive. Most of the iron mesh products are within 100 yuan, and the aluminum products are more than 100 yuan. Other aspects, such as the number of USB expansion ports, whether to adjust the speed, bracket height adjustment and so on, can also pay attention to additional options.

With regard to noise, in fact, most of these products can be controlled within 30 decibels, which is basically integrated with the noise and environmental noise of the notebook itself, so there is little need to worry about this aspect in use.

Exhaust radiator:

The principle of the exhaust type radiator is that the exhaust device is installed in the air outlet of the notebook to forcibly increase the air outlet efficiency and discharge the heat. We also bought two products, on the surface, the two products are the same, in fact, the difference between them is that the power supply is different, one is through the 5V computer USB power supply, the other is through the 12V power adapter.

In practical use, the difference is the difference between speed and air volume, and the speed and air volume of 12V power supply are larger. Judging from the actual heat dissipation effect. The effect of the exhaust radiator is stronger than that of the base type, and the core temperature of both CPU and GPU is reduced to less than 80 ℃. Compared with the temperature without auxiliary heat dissipation, the 5V power supply reduces the core temperature by about 15 ℃. The 12V power supply reduces the core temperature by about 20 ℃. In terms of surface temperature, the cooling is more obvious as it is closer to the radiator. In the main keyboard area, there is a cooling of about 5 ℃ on the left and middle.

Therefore, it can be seen that the heat dissipation effect of exhaust radiator is still obvious, but it also has obvious disadvantages. The first is that installation is more troublesome, and if you need to take notes out frequently, you have to disassemble and assemble frequently. In addition, it has requirements for the location of the air outlet, and many models cannot be used, such as some models with rear hinges can not be installed. There is also a lot of noise.

In addition, due to its forced ventilation, in principle, it may damage the original built-in fan of the laptop, but from the feedback of many users, this rarely happens. However, due to forced ventilation, it will significantly increase the amount of ash in the fuselage.

Generally speaking, the exhaust radiator is suitable for models with large heat dissipation pressure or defects, but make sure your equipment can be installed before you buy, and noise should be taken into account. The base radiator is suitable for most models with a little heat dissipation pressure, or you are not satisfied with the heat dissipation. But pay attention to whether there is an air inlet at the bottom of your equipment, if not, its effect is not obvious, which is equivalent to an ordinary bracket.

Finally, it should be emphasized that these are "auxiliary heat dissipation". The most important thing is to see the heat dissipation capacity of the equipment itself, and whether it is time to clean up the ash and change the silicone grease.
