I have a windows 10 desktop PC with asus TUF Z270 MARK 2 motherboard with Intel i3-7100 CPU & 12GB of RAM.
The CPU fan makes constant humming noise and I can deal with it. However whenever I open an application such as internet browser, WORD, EXCEL, Outlook or anything that spikes the CPU utilization percentage, the noise level goes up.
The noise level comes down eventually to a certain level after files are open (after dust settles, so to speak), but then if I keep multiple applications open at the same time, the sound goes up and down constantly on its own.
It is really annoying.
Is there anything that I can "DISABLE" in BIOS or should I simply replace the CPU fan which seems to be the source of the noise?
