Huh, that is so cool. Did not know about that. I found the sound here and it's EXACTLY what I hear in my headset!Originally Posted by robbo2
It's coil noise. Explanation stolen from wiki cause I can't be bothered
Coil noise is, as its name suggests, caused by electromagnetic coils. These coils, which may act as inductors or transformers, have a certain resonant frequency when coupled with the rest of the electric circuit, as well as a resonance at which it will tend to physically vibrate.
It's nothing to worry about.
My 6970 whines in Crysis but not folding, different uses put load on different parts. Might have correlation with how much it loads the GPU.Originally Posted by OverClocker55
