Does the host open the cover to help dissipate heat?

After opening the cover, the air duct is not present, that is, the front fan of the chassis is lost, and all hardware cooling is affected. And one is not careful and it is easy to get an electric shock. So is the host opening the cover to facilitate heat dissipation? The following small series for everyone to introduce in detail.

Consequences of opening the cover:

1. The chassis “opens the belly” and makes the hardware exposed unexpectedly. One of the main functions of the chassis is to protect the internal motherboard, graphics card, memory, data cable and other devices so that they do not directly contact the outside world to avoid accidental damage. Opening the cover of the case removes the protection of them. One of the author's friends accidentally sprinkled tea into the chassis in this state. Fortunately, there was no booting at the time, and the measures taken properly did not cause serious consequences. However, in order to ensure that the moisture in the chassis is completely evaporated and the computer cannot be used for several days, it is also an unbearable thing for a "networm".

2, it is easy to accumulate dust. Another function of the chassis is to isolate the dust from the outside world. Many hardware in the computer have strict requirements on the use environment. Many of us “networkworms”, although they are usually very considerate, they are very thoughtful about the computer, and most of them have prepared a dust cover, and they can wipe the computer regularly and wait for the computer to be spotless. Opening the chassis cover runs counter to this. The motherboard and other components in the chassis are extremely easy to accumulate dust, and many users use the electric fan to blow directly into the chassis to further reduce the temperature of the computer. In the long run, “dust” will become the killer of computers.

3, this practice is very harmful to the health of the human body. As we all know, CPU, motherboard, power supply and other hardware are high electromagnetic radiation sources, and the chassis also has a major function is to shield us from most of the electromagnetic radiation, is our healthy use of the computer "protection of God". If we only expose our body to high electromagnetic radiation for the purpose of heat dissipation, it is not worth the joke to be healthy.

Tip: Generally, the computer chassis with good design and excellent workmanship will fully consider the heat dissipation problem. They use the air duct structure to greatly improve the heat dissipation effect. If the chassis is opened, the air duct structure will no longer exist and will be weakened. The heat dissipation effect, and in order to dissipate the heat, let the computer "streaking", it is even more contrary.

The above small series introduces you to the problem that the main unit opens the cover for a long time. The consequences of opening the cover can be imagined. The hardware exposure is easy to cause physical damage, and it is easy to accumulate dust. Moreover, the host opens. Radiation is then the biggest damage.
