Penguin Power Filters--How much Noise do they make?

[TeenReefer]

Im thinking about getting a penguin 350B (the newer kind) and i am wondering how much noise the bio wheel makes as far as the dripping noise from the bio wheel goes. My tank is in my bedroom and i would like it to be relatively quiet. Thanks for any info.

As long as the tank is full the filters are pretty difficult to hear.

MY penguin 550 makes no noise at all. When I first had it on I had doubts it was running. My skimmer on the otherhand...

...virtually silent unless you use the bubbler then it is obnoxiously loud. I like them especially for undergravel pumps.

I have 3 330's, They are extremely quiet. The Biowheel Actually helps, because it slows the water a little, before it enters the tank. (This is compared to the 2 Whispers that I had.)
