I renovated the complete Kitchen including  this new hood fan FHWC3055S.
At first the noise was a concern but for that number of CFM I'm ok to accept this inconvenience. My biggest problem is on a diner with gests the hood fan stopped working after the third time usage. That was really embarrassing. 
Now because of this experience, we are not sure if we lean on the warranty or just buy another brand the fact if the warranty replace the broken part with the same problem parts.
