Quote: I'd be interested to see the circuitry inside the fan shroud/controller. Initially, you'd think it were just a large, maybe 70a relay that is housed internally. But if you're saying a variable voltage input would then use some sort of PWM to decrease or increase fan speed, there is no way that's the case. Break one open
I have a spare fan with a damaged shroud and blade. I tried pulled the motor and tried to open it. The back is epoxied on. Since it's a good spare for the one in my car I decided to leave it alone. I have a fan off a bigger car with a different shroud. I might pull it down and see what it looks like inside. There is simply no way for me to bench test it inside. I have to power it off one of my vehicles. That's tricky with a loose motor that can be as dangerous as these.
Quote: Feets, In that vid I wonder if it can take off and hover in place!
I've often thought about that too. My concern is getting a finger caught in one trying to keep it from flopping around.
