So far my experience has been positive with the electric fans i installed. Duel Flex-A-Lite fan kit 280 Pulls 5,500cfm. Listed to pull 28A. I did do more than the big 3 upgrade to the wiring also, Used 02 welding cable and more grounds, I have not hooked the fans to come on with the AC yet. Have not needed to yet. Stock 140A alternator is keeping up fine.
It is keeping my truck cool so far but around here we have low humidity and will only see 100 degree days a couple times a year.
With front and rear AC, 85 degree day and stop and go traffic once the interior is cooled down i run the AC on low or med. Seems to just work fine. I'll see on a really hot day though how it does. If it fails i did keep all the OEM stuff to swap back.
