So, I could be completely wrong about this, but... I seem to recall from the time I spent futzing around with a G5 Xserve that the fans in the G5 require a PWM signal for speed control, and that they'll either not run at all or run full-blast (at an ear-splitting volume) if you just apply DC voltage to them. (Of course, this could just apply to the Xserve, not the desktops.)
