Having the lower oil T-stat might help a but since the engine isnt fighting hotter oil to reach a lower coolant target, but still.
The radiator fan runs more than stock, but only after sitting stationary for a while. In my driving, or because of the oil thermostat, I don't see this much. I know others have reported it running a lot and sounding loud. Iirc the main radiator fan is a 1000w 3 phase/brushless motor so from a reliability stand point, it doesn't really matter if it runs more, just personal preference
