Loud when hot

My 06 6.0 is having a rough time once it get's warmed up. It gets warm but then pretty hot, but not hot enough that my temp gauge goes up. However, it gets real loud under the hood like it is either sucking for air like crazy, or like there is some kind of auxillary fan that is spooling up wildly to keep it cool. Is there an additional fan that kicks on when it gets hot or does anybody have any clue what my problem might be. It's still not to awful hot here in SC and I had it last August in the hot stuff and didn't have any issues like this. I'm still pretty new to the 'Stroker' so I'm not real sure. Any info would be much appreciated.

Mine is very similar and in my case I know exactly what it is... I imagine it sounds like it's woking against a load or something... If this is the case, yes it is the fan... Though the fan is electronically controlled it is mechanical and makes a heck of a racket... I think the same thing here in Arizona when it's like 80 or 90 and I'm blowing the A/C, "it's not that hot"... Plus I keep wondering why it kicks in even when I'm driving 40, 50 or 60 mph... You would think that at those speeds the air being forced through the grill would be much more in volume then the fan could move... I guess the engineers don't see it that way... But I sure would enjoy an electric fan instead (MUCH more quiet).....

I had the same trouble out of my 04 6.0L. It was the fan on my truck and the garage fixed it by putting a new download in my truck or something to that nature. While that fan is kicked in and making that sound, they also informed me that it takes away around 10 horses. Good luck with it.
