Noise of Computer Chassis

1. Computer chassis, also known as the computing machine cabinet, is the hardware protection housed in the outer housing of the computer. As the largest component, it plays an important role in the heat dissipation, static protection, dustproof and noise reduction of the machine.

2. As the technology update of current computers develops rapidly, and beyond the traditional hard disk cooling method, fans, radiators, and other types of active cooling equipment have become the main equipment for computers to reduce noise, but these kinds of active cooling units are usually with high noise. With such a large noise, the use effect of computers will be significantly reduced.

3. Under such circumstances, computer chassis noise reduction technology has become an important factor for the comfort of consumers. In particular, loud noise is the main factor hindering users from enjoying the computer. Therefore, in order to make the computer more comfortable to use, the noise reduction technology of the computer chassis is particularly important.

4. At present, the noise reduction technology of the computer cabinet mainly includes noise damping plates, sound absorption materials and other equipment. For example, the noise damping plate used in the computer casing can reduce the noise caused by the impact between the computer components and the housing in the process of computer use.

5. In addition, during the use of the computer, the sound absorption materials such as the sound insulation cotton and sound insulation cotton can also greatly reduce the noise generated in the computer. Through the combination of these two noise reduction methods, the noise caused by the operation of the computer can be suppressed to a certain extent, ensuring the user to use the computer comfortably.

一、电脑机箱噪音

电脑机箱噪音是指由于硬件配置不合理或由外界环境干扰，导致内部机箱产生的吵闹和啸叫声，影响环境和操作，因而产生负面影响的声音。电脑机箱噪音大多数由多个因素共同作用而发生，其中包括机箱内部硬件状态、外界环境特征和外部电磁干扰。下面我们将进一步了解电脑机箱噪音的原因和预防措施。

二、电脑机箱噪音的原因

1.机箱内部硬件状态：首先，电脑机箱内的电路板、硬盘、光驱、风扇及其他组件状态不良，导致机箱噪音增大。

2.外界环境特征：环境湿度、温度参数，不仅会影响电脑机箱运行效率，也会增大机箱内部硬件状态不良导致的噪音增大。

3.电磁干扰：室外环境电磁干扰会通过电脑机箱外壳及各种电缆，把机箱内产生的噪音释放到外部环境中，导致电脑机箱噪音进一步增大。

三、电脑机箱噪音的预防措施

1.合理配置硬件：在配置硬件时，应避免将冷的电源，加热的CPU，复杂的显卡和其他组件所在的插槽放在一起，这会增加机箱噪音，应让那些发热较大的硬件物理分开，以降低机箱噪音。

2.定期整理外接电缆：外接电缆若长时间拧成紧绳，很容易受热变形，且会通过电磁干扰，给电脑整机的噪音增添不少噪声，因此应定期给机箱里的电缆整理，以起到降低电脑机箱噪音的作用。

3.更换风扇和散热器：如果风扇的故障致使机箱噪音大幅提升，我们应及时更换新的风扇，以防止噪音持续增大，还可以在机箱中安装散热器，以起到降低机箱噪音的作用。

四、结论

电脑机箱噪音是源于内部硬件状态、外界环境特性和外部电磁干扰等诸多因素，严重影响环境和操作，因此应定期清理内部插件，更换风扇和散热器，给电缆整理，以防止并减少电脑机箱噪音的发生。
