I run 2 of those, one in each tent. I buy expensive fans cause they are much quieter, don't wanna ruin them with cheap controllers.Speed controllers kill your fan. It just clips the sine wave and starts and stops it repeatedly. It can cause hums and shortened fan life.
I use a variac that adjusts voltage. Smoother and quieter and easier on the van.View attachment 3762193
