The engine thermostat should take care of the block.
Keep in mind the rear of the coach is a low pressure area which naturally pulls in air from the side openings and exhausts to the rear.
No argument that less thermal stress is not better.
What I noticed when the solenoid on the fan controller failed is two things. One, it cut the fuel mileage about 1 mpg. Two, the engine was not operating at its design temp. The Detroit tstats (2 of them are full open at 196), with the fan on high all the time the engine operated in the mid 180’s.
