Thanks for the info guys. After looking at all kind of controllers yesterday I just ended up getting two Adjustable Derale Fan Controllers. I looked at the Derale 16789 a Dual fan High-Amperage Adjustable Fan Controller but couldn't find the max amps that it worked with. I also looked at some of the other big amp dual controllers out there.
In the end I just needed something to tell them to turn on. The fans already came with the wire harness and relays.
