Review on 🌬️ AC Infinity AXIAL S1238, 120mm Muffin Fan with Speed Controller - UL-Certified for Efficient Air Circulation in Doorways, Room-to-Room, Wood Stoves, Fireplaces, and Similar Projects by Chris Kirby

Item arrived quickly and exactly as described. I have to say that it works much better than I expected given its small size. I bought this for my home office door as my computer gear heats up the room unless the door is fully open. That thing moves a lot of air! The only "complaint" I have (although I'm not really complaining) is that once you crank it up above average it gets very loud. On the plus side, it moves enough air that I didn't have to go above average. At low levels it's as quiet, if not quieter, than the fans in my computer tower (and they're all new and quiet).
