Prime95 - High Pitched sound when torturing the system?

post #1 of 9
Thread Starter 
When running torture tests I get a strange high pitched sound from somewhere on near MB/Ram/cpu? Is this normal?

It seems to be on/off every like X mins.

I'm just wondering if there's anything wrong.

I have no fans that could make this sound, and I have also eliminated the WC pump.

Thanks
My System

Sounds like cap squeal.

Normal, the gap in the noise is due to when Prime95 stops calculating and dumps to memory then starts again.

Well, I say normal it does depend how loud this noise is I suppose. I get a sort of whining noise which is audible above the 6 fans in the case. It is just the increase in current going through the circuits, some is converted to heat hence the need for fans etc and a very small amount is converted to sound.

With better parts this sounds doesn't normally occur as much until higher voltages, vice versa; with cheaper parts this sound can occur under medium load as well as extreme.

Kinda like a teapot when its about to get to the boiling point? Lol, that's scary. I've heard of PSU's making a whining sound when stressed.

screaming caps . There was a post explaining it and the mastery behind how it makes the sound and affects components .

But usually it's not extremely damageable and will just make the component last shorter .
