Dometic used to have small absorption fridges. (I had one in a tiny house, and it was totally silent.) Not sure if they do nowadays. (Peltier effect fridges have taken up some of the steam these days, but I'm pretty sure those have constant-running fans.) I think Dometic is still big in the sailboat community, which is another good place to investigate.

Most propane fridges are absorption style. I don't know if they're up to code for running inside a house, but they'd probably be fine on a porch or in a garage.

Check out Lehman's (https://www.lehmans.com/category/gas-refrigerators-freezers) for a lot of alternative technology.

Otherwise, google for 'propane refrigerator' or 'gas refrigerator or 'absorption refrigerator.'

If you really want to get creative, and enjoy processing food, there's lots of fridge-free ways to preserve food, depending on the climate you live in. It's also a fun area to research and experiment with.

Oh, one more thing -- chest freezers can be converted to chest fridges with a simple thermostat-switch. As most cheap chest freezers are manual-defrost style, they tend to run their compressor less, and for whatever reason, aren't as noisy as standing fridges. I personally still wouldn't want one in my main living quarters, but as they tend to be pretty cheap to buy, it might be something to try.
