But are they quiet? (not meaning to thread-jack!)
I just read an article of quieting down a Via, and the guy said that "great, not it can't be heard over my 120mm fan"!!! I was thinking that I wouldn't hear a pump at all, I mean no nothing. Are mag drives this, or Hydor or anything else?
BTW, here's a great place to get Danners, real cheap:
