Possibly... but the ARE the best.
I purchaced a handful of good brand name quiet fans, and panaflo was significantly quieter, yet still moves as much or even more air than its compeditors. Plus i noticed it can handle high static pressures slightly better too, without the whine you get with ball bearing fans.
Panaflo deserve praise for trying something new and different, rather than just getting a standard sub 2500rpm fan and calling it "quiet" or "silent"
