i have heard good things about the pabst fans...supposed to be pretty quiet.
and the loudness is not always determined by the rpm!
i have some little tiny fans that are pretty slow, but are pretty loud.
and i have some larger fans that are much faster and about the same volume.
i think it has most to do with the fan blade design, and how it cuts thrrough the air...after that, then rpm plays a factor.
