The fridge rear fan is intended to cycle on and off as needed. There is
a temp switch high on the fins and when those fins get too hot the temp
switch triggers and turns on the fan. After a while the fins get cool
enough to turn the fan off again. If your fan runs constantly then it is
likely inadequate or the temp switch has a problem. If it cycles as
intended I don't know what you would gain by adding fan capacity.
