Panaflo Fans?

I know that everyone loves these fans and everyone recomends them. They look like normal fans to me is their something special about them that I am missing or are they just ultra quiet or something? Can someone enlightin me? Thanks.

They are good quality fans and they have Hydro-Sleeve Bearings which make them last longer and quieter. I personally have 5 in my system right now.
