For a while my computer have been making a electric leak like sound whenever the CPU usage gets high. However, lately it started to make it more often. For example with anti-virus searches and malware search softwares, the CPU usage goes up to 80 percent and this weird noise comes from the CPU.
This sound sample i have recorded for you to picture the sound. This was recorded with microphone very near to CPU. The background humming noise comes from the fan, but I am very certain that this leak-like sound does not come from fan because it does not have a specific pattern and only occur with high CPU uges. The CPU usage was around 80% in this recording.

For information, my configurations are:
Intel Pentium 4 CPU 3.00 GHz
2 GB RAM
Motherboard MSI 915P/G Neo2 Platinium ed.
so not that bad.
" Note that 15-20 Hz is quite low frequencies." Yes, but they're also completely irrelevant frequencies, since the quote talks about "15 – 20 KHz"... Those are pretty high for humans: they're at the top end of the range of frequencies that a given average adult will be able to hear. – underscore_d – 2018-01-17T22:54:51.780
@Marcin Do you mean capacitors on MB? Does that mean that replace MB will likely make a difference (in terms of less/more noise)? I am trying to figure out if CPU has to be replaced or if MB has to be replaced. – user482594 – 2020-01-31T18:33:09.337

Your answer may very well be correct for this situation, but just in case you're trying to say that a processor never makes any sound: unfortunately, "cpu whine" is not too uncommon -- http://search.yahoo.com/search?p=processor+OR+cpu+whine (sometimes only occurring when the processor is not very busy)

@Marcin and @nik: thanks for that info. I guess I was totally misled by the name "cpu whine". (Too bad Dell thinks "The noise is normal", just like Apple did for their MacBooks. The high-pitched whine can really drive one crazy...) – Arjan – 2010-01-19T13:59:08.183
