Same here, far too loud for 24/7, but fine for benching of course For 7v, swap 5v for ground. For 5v, swap 5v for 12v. Only do this with the Tornado's connector (or a separate pass-through), and don't plug anything into the other side, or it will get incorrect voltages and (depending on what it is) die horribly. What I've done is get 3-pin to 4-pin fan converters, cut off the 3-pin bit, and then swap the pins around in the molex connectors, then use them as pass-throughs for the Tornados/other fans I want to get that voltage only.
Cheers, i'll definatly be doin that soon, as in i'm currently closing everythin down 2 unplug the fan Death
