what kind of signal/circuit is required to control the speed, if

Put them BACK in the large Sun servers if they're anything remotely
recent.
It's almost definitely a tachometer lead. They're typically
controlled via PWM, with a closed-loop servo for speed control and
OS-accessible speed monitoring.
