Another reason might be that the oil cooler in the air exit path of the
water radiator is an obstacle that hinders the air flow in the water
radiator?
Looking closer to both radiators, It appears to me that the oil cooler
has closer spaced fins, thicker fluid canals, and an overall smaller
useful area.
It might be that this is the reason why lowering the oil radiator also
causes the water temperatures to drop.
