Over the past week or so as the truck gets to the higher RPMs, the fan is really LOUD.. loud enough I can hear it over the exhaust. It has never sounded like that before. Is the fan clutch froze up? or is my water pump going out and what I am hearing is the vibration???
Embarresed to say I haven't even popped the hood and grab the fan to see if there is any slop or not...

I'd guess its the clutch froze up. I see it all the time on the Ih 466s and We've had it happen to 2 of our cummins.
92 D350 Cab and Chassis. Auto stock, wiring gremlins. 330k miles
92 W250 Ext cab rotted completely out. Auto, pump maxed, 215 ppump nozzles, Denny T2 pin.
85 D350 single wheel, converted to cummins, getrag, turned up 2 turns and afc screw flush.
