All the newer Rams have electric fans attached to the radiator, they are not belt driven fans. Most truck (and car) cooling systems after about 2,000 have the electric fans on the radiator. The belts only drive the water pump. and other accessories.
Those electric fans replace your fan shroud and are independent of the water pump. You can buy them thermostat controlled, and powered through relays. Some of those move a lot of air. Those electric fans solve a lot of problems that belt driven fans can have and are very efficient.

Might be worth looking into.
