Fan clutch question...

I think the stealership is at it again, but before I go back at them with both barrels, I'm looking for an opinion from you guys.

The fan clutch seems to be sticking at startup for a couple of blocks, when the engine temp is low, like below 100 degrees and I take off down the road. The fan starts roaring like it might do when it extremely hot, which its not.

It didn't do it this winter, but now that is hot outside it does this. But the motor is not hot.

The stealership is telling me the this annoying roaring noise is normal. I say BS.

Do other 6.4's do this?

My 08 6.4 did this and I thought that it was the fan clutch but the dealer said that everything was OK. Well, it was a tranmission sensor and the noise was the transmission cooler fan. Finally threw a wrench/CEL at 10k feet uphill at 10pm. Dealer fixed it the next day. Might want to check the transmission sensor and fan.
