To the experts among us: I have a caravan with a fridge 12V/gas/220V. Here I am particularly interested in the 12-volt operation in terms of the cooling properties. I have not had a single wowa yet, in which the 12V operation was satisfactory. It is more an emergency solution than that it really does. Even the pre-cooling hardly lasts for a day, especially not over two. To improve this situation I remembered, the radiator ribs on the back of the cooling sc I imagine 3 of these fans next to each other, so that all the radiator ribs are ventilated. Does anyone have any experience with this? Does that bring something noticeable? Nocturnal greeting Aspergius
