If they don't have an RPM sense line (they only have molex plugs), not really. What you can do is:
That guide has you change the fan side wires, so you actually give the fans 7v or 5v instead of 12. So you don't get fan control, but you just run them at a lower voltage and thus lower RPM at all times.
It would be a little more complex, but another option might be to put in a linear potentiometer to control it, with the knob somehow affixed outside the case. It would be manual control, not automatic, but at least it's adjustable. That's basically what this is, but if you're comfortable soldering you might be able to DIY it cheaper.
