Increasing Airflow through Condenser.
The new DC only compressor fridge I will soon have in my possession has a 92 mm computer muffin fan pulling air through only a portion(~85%) of the ~120mm tall condenser. It then blows this warmed a...

Landyacht, let me see if I've got it right.
With resistor removed, the RPM went down from 2500 to 2000 (1.25 drop), and On cycle increased from 25% to 30% (1.2 times increase). Assuming that RPM correlates closely with watts, you've achieved 5% energy savings. Plus, reduced noise due to lower RPM (don't recall reading exactly this, but probably). Given 20-30 Ah daily draw of this small fridge, 5% is mere 1-1.5 Ah a day. This is - if there were 5% savings achieved, which can be confirmed only by measuring the daily draw. I realize that noise level was your main goal, though.
