I like all the approaches as a whole, and each one may work better for some vehicles and not others. You don't want your oem cooling fans turning on earlier or staying on longer than they do without a new grill shutter mod. The e-fans eat mpg on their own. I always wanted to just shut off the seconday fan for my a/c once i was rolling 30mph or better, especially if its really hot the regular fan may be on too anyway and pulling air thru the condenser already
