Hi folks Definitely the new blower is noisier with more air flow noise- seen a couple that had 60 hz hum (like a resonance) that is annoying. I'm a fan of the old blower as well. Funny too, there is lots of stoves with old blowers out there working just fine. I think that if you need to run your stove on 3-5, to get adequate heat, then the new blower is best for you because of the additional airflow and heat stripping. If you can use it on 1 or 2 most of the time, the old blower will probably work just fine unless you have some exceptionally hot pellets. Its all still a work in progress. The inserts seem to have more issues but not really, its just we sell more inserts..... anyway, good luck to all.
