Tales from a Ventilation Lunatic

[Roadtripp]

Good to hear the Papst fan is proving useful. Mine is still in the box waiting for the build to progress and hotter conditions. That’s a long wait sometimes around the Puget Sound region. We think about better heaters for months on end. But that’s why Im building a home with wheels. 
Thanks for the data on ventilation and other information. I need to review the PWM speed controller options as full speed is not always ideal, a bit noisy too.  I use background noise also, white noise, due to some high pitch and hissing sound I hear. It’s not severe. It comes and goes. But I can tell it could become a nuisance if it was more intense. 
 I wonder if Dyson fans perform better than other fans? Or is it curb appeal and glam, looks. Due to space limitations I like the computer fan form factor. 
 I thought the idea to have a squirrel fan blower under the vehicle was interesting placement and strategy. For the cool air like a sea breeze. 
 Im also wondering about the little motors and propellers on drones?. For air circulation. I noticed packages of 4 motors for $20-$30. Just curious if they might be useful. I’m just curious. Ive no experience with these motors. The noise might be too much. Maybe they spin too fast:
