Air-cooled generators are smaller, less complex, and more fuel-efficient, making them ideal for small-scale applications.
However, Liquid-cooled generators are slightly larger, more powerful, and more efficient at dissipating heat which is extremely important for extended power outages.
I've encountered too many air-cooled generators that have ceased functioning and needed replacing due to overheating, especially in LP generators which run at a higher temperature and RPM than a diesel generator.
I have a small diesel Kubota generator, liquid-cooled, and is > 20 years old.
Diesel that is "cut" with an additive for cold temperature locations requires only the glow plug to start reliably and fuel gelling has never been an issue.
With respect to noise, there are many aftermarket add-on mufflers or baffles which will quiet even the loudest generator.
I would add the following:

Thank you Wolfgang, more perspective is always welcome to help the conversation.
Great Info, thank you.
Your welcome, glad to help
Good info. As probable blackouts increase, interest in generators will also increase.
