In the process of having lots of exciting issues with my genset, I've done some reading and concluded that I ought to be able to swap the squirrel cage fan with a fancier/quieter one.
First, I'd like one that is a sealed unit, because my current one is dying after ingesting a lot of dust.
Second, it appears that the belt-driven approach reduces noise considerably. I'm not really sure why that is, but it seems to be gospel.
Third, and probably most important, the stock (Powertech) fan runs at full bore no matter. But, a lot of the time, I don't believe we need nearly those 2200cfm through that radiator. Cool days, cooler nights, etc... should be able to run at a much lower speed. So I think I want to try to find a variable speed fan and a thermostatic controller. I am going to start by having a look at what the Prevost converters are using.
I'll update this thread as I make progress (or not).
