How to improve the noise characteristics of the system unit of a personal computer

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.
Usually, several fans are installed in the system unit: on the processor heatsink, on the video card (if there is an active cooling system), for blowing the hard drive, for housing ventilation, in the power supply.

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. On the other hand, since all modern processors, including graphic ones, are equipped with energy-saving functions, the heat dissipated by them under low loads is small. In this case, the fan or turbine of the cooling systems installed on them practically Continue reading
