PWM radiator fan controller

Thanks Andrew. Looks like there are quite a few different options with either of these systems. I'm wondering what the minimum system is that will meet my needs for this particular job? Perhaps, since you're not familiar with them, someone else will have some advice, or can at least point me to an article that's a good starting point for understanding what's involved.

In order to do this, you need to get either HP Tuners or EFI Live. I don't have experience with either, so I can't recommend one over the other.
