You're going to drive yourself nuts looking for "the best" and hoping that every posted opinion correlates with the same item. It ain't gonna happen. There's more than one good fan on the market. Buy a quality centrifugal fan whether it's a Vortex, a Can, or whatever. They're all good products. Good luck.

To be fair , I was only looking for the "best" for my particular application. Finally made a decision though and decided to go with Elicent. I'm sure I'll be more than pleased.
