Haltech 2 Speed Fan Controller?

2 Speed Fan Controller?
I have a dual fan shroud setup that I got from Summit. I was wondering if there is any way to control this via voltage with 2 speeds. I couldn't quite find any controller to do this with the Haltech outputs.

You could use two outputs and a set of relays with a resistor to offer two speeds. Would need a heck of wattage rating on the resistor I would think. Or you could pick up a solid state relay and use one output set to PWM fan control and have infinitely variable speeds.

Toyotas have used a system to provide two fan speeds by running the fans in series for low speed (each one being the resistor for the other). Then switch them to parallel for high speed. requires three relays.
You need to be careful with running electric motors at lower voltages or even with PWM. some motors don't like it and may not last long running like that.

I am building my current setup utilizing two of these:
30amp DC pwm fan controller.
30A Motor Speed Controller (PWM) - Cana Kit
they also offer a 50amp version:
50A Digital DC PWM Motor Speed Controller - Cana Kit
The nice thing is it doesn't require a pwm input. standard reference voltage input, so most outputs from any ecu could be used, or even a simple thermosensor of some sort with a signal conditioner for fully automated function. And it would be easy to wire in a bypass switch to be able to switch them on full when you wish.
