Any feedback on how it's working?
Definitely looks like it could move plenty of air. Looks like an easy install job as well.
I did a fan mod on my OBS several years ago, where everything but the blade was on the back of the cabinet.....but that blade and shaft were constantly gooped up and I eventually quit using the fan for most of my smokes. I found it worked ok when the load was light, ie. almonds, a few racks of jerky, salmon etc. Not so well with heavy loads like a pork butt or whole chicken. I just don't think it moved enough air.
