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 Tom Childress

Nice little fan. Like the other review I just read, I use it to circulate heat from one room to another. He seems to be doing his job, but he certainly isn't doing it quietly. I'm in the next room and on a low level I can hear it humming. At maximum setting, the buzzing (or is it a howl?) disappears due to the sound of the furiously spinning blades. And when I turn on the TV, I'm pretty sure I don't notice the noise. The bracket that attaches the fan to the wall is oddly designed, but it gets the job done. Bottom line: don't plan on using it where you need quiet.
