Fridge Vent Fan Questions
Two questions, and I would appreciate the wisdom of the crowd: 1-I want to add vent fans to my small 5ver's fridge 'chimney' to improve cooling. I intend to use 2-3 computer fans. I assume it would...

Heat, in the right amount and in the right areas of the cooling unit, is necessary for an absorption refrigerator to work properly. A correctly installed fridge shouldn’t need any more than a small airflow assist in doing what will occur naturally. Heat rises, and as long as the upper and lower vents are sized according to the installation guide, and the proper clearances and baffling are maintained, the air WILL flow up across the coils and out the upper vent.
It isn’t necessary to fill the roof vent or chimney with fans in order to make the fridge work. By doing that, you’ve effectively reduced the size of the upper vent by about half, and possibly created an environment where the fridge couldn’t function without the fans. You shouldn’t want that any more than you’d want a bird building a nest on top of the chimney screen under the roof vent cap.
At the most, a single 120mm computer fan placed in the area between the upper and lower coils is all that I would install. I would choose the fan type by how quiet and durable it is, not on how many cfm’s it moves. It doesn’t take much.
