I assume you have a fridge with the coils underneath? The fan not only helps to move the rest of the heat out from the coils but also keep air flowing around the compressor.

Just keep in mind the appliance was manufactured with a certain tolerance in mind for airflow to cool off the coils, as well as the surface area for the coil. By adding material you raise the mass and the ability to absorb heat but also reduce surface area and potentially airflow. This could potentially reduce efficiency.
