I finally got around to tuning my fridge a bit more:
1) I have installed two old PC fans (free, I haven't used them anymore) connected to molex-PC fan reduction ($1-$2) connected to USB-molex reduction ($0,6), connected to outlet-USB adapter (free with old cell phone)
2) installed insulated box around outlet of evaporator from freezer and inlet of evaporator (before expansion valve). It should work as subcooling heat exchanger (albeit the heat is exchanged by air, so not a big deal)
First measure lowered consumption from 0,7kWh/day (fridge is 8 years old, long are gone times when it consumed around 0,54kWh/day) to 0,53kWh/day
Second measure is on edge of rounding error of 0,03kWh/day (to just barely under 0,5kWh/day) so it's probably not working as intended. Unfortunately there is no way to connect the two pipes that I'm trying to cool/heat by each other
