Oh and the reason why we can hear it clearly on his GTX570 because he has a different cooler also so nothing that can block the sound (naked PCB).

Oh btw tip for overclockers, difference ingame from 900MHz to 950MHz result in 2-3FPS more but you need a bit more voltage to obtain stable clock and you will get higher temps in my situation it will result in 7 to 9 dregees hotter so it wasn't worth it.

People that use watercooling or any other cooling solution that won't be needing the power pins on the PCB of the GPU you can best set fan min and max to 0%, you need less voltage for your clock.
I'm not seeing how this could be the case, with no load (due to fan not being connected) there is no current draw from the fan circuitry, and setting it to 0% would not be giving the card any 'extra power' as it were.
