I have a 6" exhaust fan that is a little louder than I’d like. I have the silencer on it which helped a lot! Now I’m down to just motor noise pretty much. Do you know if I can insulate this motor? It’s significantly quieter with a blanket wrapped around it. Not sure about it overheating. I would think the airflow cools the motor. I’m wondering if anyone has insulated theirs. So far it seems cool still but I’ll keep checking.
