In my experience, it didn't happen often. but once it occurred. the problem was hard to fix.
my 1st one was a new boxed AMD CPU and its motherboard. the CPU fan really loud. I never met the problem before. AMD mailed me a new fan. after replacement, not much improvement. I had to leave it that way then moved PC to another room as I couldn't work when it's in Office.
the 2nd one was when ASUS motherboard replacement. the board worked fine but CPU fan was running loud. I tried another CPU fan, re-seating CPU, adding CPU glue, , whatever I couldn't. per ASUS guide the board had a CPU fan control circuit. my conclusion that it must be NOT working any more. I had to let it retired.
my 3rd was a HP DM PC. this model typically run very quiet (good experience on HP 8000-8300, G1-G4). but this noisy one is right like you said, when running heavy load (data-processing, graphics, gaming, , , sounds like air-raid siren. I still use it sometimes.
my summary,
if it's a CPU fan problem. then likely fan replacement can solve the problem. but if it's an issue on CPU fan control circuit(built-in motherboard), then it's NOT easy to fix. or can be fixed at high cost.
I have to fix it, otherwise it will damage my hearing and the neighbors will start to complain soon. Honestly, I've used and worked with computers since 1994 and I've never encountered something like this.
And I'm not gonna pay more than I've already have done when it comes to this computer.
What if I pull the plug to the hellish fan and attach a new fan to the "wall" opposite the motherboard?
