When using a home personal computer to watch movies, listen to music or browse the Internet, especially at night, the noise of the system unit becomes especially noticeable. Permanent noise sources are active elements of cooling systems (ventilation) and hard disk drives.

The most energy-intensive components of a personal computer are the central processor and video card. Accordingly, they have the most powerful cooling systems, which are the main sources of noise.

In this case, the fan or turbine of the cooling systems installed on them practically Continue reading
