Yep, you can hear them when they ramp from 100% down to a lower setting. I've even tried the different impellars and voltage amps per Tunze. Next, I guess Tunze will be reworking their magnets. Its not everyone of them, but they are aware of it. I've also heard that the European ones might not have the same issue![]()
Are they going to be offering replacement magnet? I guess what confuses me is the the European got the new models first, so why are they not having the issues?
