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.
