The traditional computer has a loud boot sound.

It is common for a computer to be loud when it is turned on. But when you enter the system, the sound becomes smaller. Why is this? This paper will analyze the reasons why the sound is loud when the computer is turned on and becomes smaller after entering the system.

CPU usage soared.

When the computer is turned on, it needs to detect all kinds of hardware, load drivers and services, and the CPU utilization rate soars to 100%, which naturally generates a lot of heat when it is busy. In order to ensure the safety of hardware, the cooling fan must run at full speed, resulting in great noise.

Intelligent adjustment of fan speed

After entering the system, most of the work has been completed, and the CPU utilization rate has dropped rapidly to 12%. At this time, many motherboards have intelligent functions, which can automatically monitor the hardware usage. The motherboard will intelligently adjust the fan speed according to the hardware load, thus reducing the noise.
