IMO, the top / outlet hose is not the ideal place for the sensor / switch. That will switch on fans based upon the coolant temperature leaving the engine. Others may disagree, but my view is the best place for the sensor is in the bottom hose / return to the water pump and engine. That way you're measuring the return coolant temperature, and if vehicle movement provides enough airflow and cooling the fans won't come on. A second choice would be a probe that goes into radiator fins.
Once downside of the bottom hose location is you may need a different sensor / switch if the one you have isn't adjustable. You may want to switch on fans at a lower temperature if you're reading it from the water pump inlet temperature / lower hose.
