Vortex II fans
Getting a new TT Monday. It, like most TT's comes with a weak, under powered fan that would be hard pressed to blow out a candle. In other trailers I've purchased, I have a Fantastic fan installed...

More importantly, both of the (different) ones that I bought produced a high-pitch noise when operating the Vortex fan. I did not have the noise when I connected one of the PWMs to my range hood fan, so it has something to do with the Vortex motor.Be sure to bench test your unit before installing it if you choose to use a PWM controller.
The PWMs on eBay are cheap and some do run at a frequency that does produce noise. My son added one that was dead quiet, the first one I tried produced an objectionable noise, the second one looked like his and performed well. A quick check didn't turn up the exact model I used, so bench check one and try another if necessary.
