I then switched to a JK fan set up with a MUCH better shroud than I had and it made a noticeable difference. Still would get hot when I hammered down for long periods of time but nothing that concerned me. I now have a dual derale fan set up that will push 3750 cfm but I have yet to test it out


Edit:
Running on the lean side will make it run hotter as well. Did you replace injectors or are they still the factory 6.0 ones?

It's on the fat side. I prefer to be safe. I did replace the injectors with larger. As well I run an afr gauge in my dash to make sure I don't lean it out.
