3500 overheating

Morning guys this is a long one.

My head hurts because of my 97 3500 7.4. overheating
Lets start with what I did.
Replaced the head gasket. Heads and block were cleaned> Head gasket took the fall.
Replaced water pump, t-stat (195) water temp sensor, water temp switch. New radiator, fan clutch.
Flushed out the water passageways, flushed the oil passage ways.
The engine fired up no problem and no DTC's and purrs but the temp goes up as it sits there and idles.
The only thing that I can find is that the aux fan will not work?
I direct 12 to the motor and it works. I tested power coming out of the connector to the fan. Relay is good. Fuse is good. ( switched both of these.
I turned on the A/C to see if the fan would work but nope.
Im out of Idea's guys and could use some feedback. I want to drive my truck again. Yes the Camrys mileage is great bit its not my truck. Thanks
