I will take an LED fan and place it in a container and pour distilled water over it and film it while it continues to run if you'll send me $20 per quart of water

That's not an adequate test. Seriously. Take a cheap fan you do not care about and plug it in and dunk it into a bucket and I betcha $5 it will keep running.

It's a brushless DC motor and the windings are sealed with shellac
