Re: fan a/c advantages

You absolutely want the fans to come on high when the AC is on. The main reason for not running the on high all the time is for noise, and possibly fan life. I have several swaps that only have one fan and it comes on high whenever it comes on and have never had an issue with cooling. I have had to replace the fan motor on one car, but that swap does have over 120k miles on it so I suppose that's to be expected.
