So I'm ordering the 3fan kit from dirt bound offroad. There out of there controller so I'm looking for the most releible controller.

 

I use the Painless Adjustable Temp switch. The install was truly painless. It's $90, but worth it. Pro-Comp (not the suspension/tire company) fans are a how lot cheaper than dirtbound. Search "12in electric fan" on Amazon. I use two 14" on a '97 XJ, but should have went with the 12in. Both fans cost me $40. So, $130 total (plus $5 for the in cab toggle switch).

 

One more thing...I initially added a t-fitting similar to Dirtbound's switch. The temp reading was way off (about 20 degrees). Not kidding, I ran two "before & after" test with an Edge CTS just to be sure that's why I went with the painless switch for the passenger side (car right) and splice the old OEM connector from the driver's side (car left) fan on it for it to come on at 220deg.
