I know on Lous Change build thread they installed the same controllers. I will have to find it and see what fans they ran. They used 2 corvette controllers on it.
Thanks again, I understand it a lot better now.

I can't imagine that an 80 dollar fan is anything fancy. I really don't see a link between PWM control and whether a fan motor is brushless or not. The ECU send a duty cycle command to the C6 controller, based on that command, the controller adjusts output voltage to the fan. It's as simple as that.
I think using 2 controllers is overkill. What's the current draw of the 11" Spal fans? My guess is that it is under 15 amps each.
