While the car is moving air is helping cool the engine and coolant before it goes back into your engine.

While you're going uphill, there is more load on the engine than if you are on a flat road. So your engine is working harder to get up the hill which in turn is producing more heat. And if your coolant is that hot your fans should be on even if the A/C is off which I know you said they do.

Wish I could diag this car in person.
