I wouldn't. The paint can only interfere with heat transfer and isn't needed
for corrosion protection. Ever see an A/C radiator with paint ?

Pros :
Less drag on engine means slightly better performance and fuel mileage, maybe
even less heat.
Less noise.
Less chance of a fan blade going into the radiator after a rock or whatever
finds it's way into the fan. (I've lost 2 Triumph rads this way)
With the mechanical fan out of the way, the electric can be mounted as a puller,
where IMO it will present less resistance to airflow at speed.
Cons :
Electric fan must move enough air for engine, rather than just being a 'helper'.
No backup if electric fails.
