For what it's worth, the fan you have already on your '17 is exactly the same as the fan you're looking to replace it with, I think they upgraded it on the '14 and up rams. I just did this on my '18, I purchased the V6 fan and other than a little bit better shrouding, it's the exact same motor. Honestly all you need to do is get rid of the clutch fan, the electric fan will work fine. If you wanted to go with a 180 degree t-stat then you'd probably want a tune to set the fan kick on temp lower. I can tell you with very spirited driving in hot temps my '18, with a 180 t-stat NEVER gets hot and the stock fan is more than enough to cool the motor.
