Honda generator enclosure fan question
I am putting my Honda EU2000i in an aluminum truck type tool box on the rear of my Toyota. I would like to be able to run it with the box closed. I have most of it figured out, wiring, exhaust and s...

I am making some progress on this, I refrain from posting here as I have constant issues and often give up.
In order to make a seal between gen and separator wall I decided to order a sheet of Soundown online for $80.
I am still running experiments on temperature's and baffles it looks like I will be leaving fans as it keeps the generator temperature lower. I do not think the fans will survive the heat long term so will be redoing eventually.
I keep looking online for info on this mod and there is very little available.
While I'd have to applaud you for your persistence I'd have to disagree there's "very little" information available online that would lead you in the correct direction on this project. Yes, there is a lot of misinformation but if you're selective there is also some very good information out there. I myself earlier linked to jauguston's design which is based on sound engineering principles and which I know does work quite effectively as I built my own version of quiet box using his plans as a guide. YouTube also links to quite a few Japanese designs that are also quite effective.
JMO, but you're making this more difficult than it needs to be. Your Honda EU2000i genset box does not need any exhaust fans as the genset itself is quite capable of exhausting hot engine cooling air and hot exhaust gas on it's own. Your concern over fan longevity when exposed to these hot gases may be well founded, though unnecessary considering there's no need for an exhaust fan anyway. If you're going to use a fan at all it should be for the purpose of helping to supply fresh cooling air to the engine but as jauguston proved it's not absolutely necessary. I did add one to my own design because I intended to not run the box out in the open but in my enclosed Avalanche cargo compartment and used the fan to draw outside air into the compartment. As for your attempts to seal to the genset's exhaust bezel I've already pointed out two different approaches that are each an effective solution - either my own DIY approach using a $10 heating duct from Home Depot or the more elegant, purpose designed solution from Generator-Line, either of which would solve any overheating issue you may have with your current design.
