Yate Loon Fan Substitute

I'm looking for fans that have the same sound profile like the Yate Loons, but at a 140mm size as currently there aren't any high speed 140mm Yate Loon. CFM has to be at least 88CFM as currently the air pressure in my case is slightly negative and I intend to keep it that way.

Edit: I knew there are 140mm high speed yate loons out there, but they seem to be of varying qualities if not gotten for certain distributors.
