If you wanted a separate freezer section, I recommend finding out where the coils on the inside of the chest freezer are, and building a small insulated box around them (just use some foam-and-foil panels). Inside that box it will be colder than the rest of the 'freezer'. If you make sure that the temperature sensor is inside the box, you won't even have to modify it electrically - the rest of the 'freezer' will be naturally at a warmer 'fridge temperature'.

Ok, how a fridge/freezer works is that it has two coils -- the cold coil (called the condenser) is inside the box and the hot coil (called the radiator) is outside the box. Heat moves from the cold coil to the hot one.

Almost all coldboxen have the condenser hidden, so you can't see it from inside the box. Some coldboxen (like your minifridge) also hide the radiator. Mine doesn't, so you can actually see a coil of metal tubing on the back which gets warm when it runs.

In summary: adding insulation to the coldbox = good. Adding insulation between the radiator and the rest of the room = bad. Adding insulation between the radiator and the inside of the coldbox = good. Anything that lets the radiator cool better (e.g. adding a fan, keeping dust off it, immersing it in cold water(provided it won't rust)) = good
