What's the matter with the loud computer exhaust fan?

When it comes to computers, I believe everyone is familiar with it, and you can see its shadow whether it is work or study. However, in the use of computers, there are often more or less problems, most of which are related to usage habits. So what's the matter with the loud computer exhaust fan?

1. The sound of computer exhaust fans is mostly caused by hardware or software.

2. In terms of hardware, for example, there is a lot of dust or too much debris in the exhaust fan, or there are problems with the shaft and balls of the exhaust fan.

3. In terms of software, if the CPU usage is high, overheating will speed up the fan speed, resulting in loud fan noise.
