Case fan voltage controls

[MikeReiner]

Ok, so I want to buy two of these.

Is there a way I can hook both fans up to the same control knob, instead of having two?

If you wire them both to the same output terminal of the (i assume your using one) potentiometer/control knob then in theory the voltage would be split between them i.e. if the output of the potentiometer is 7v they both would get 7v (maybe +/- a few milivolts )
