When checking the EBM-Papst site (http://www.ebmpapst.us) the 92x92x25 mm fans did not
reach the same CFM, but those that I found (3212JN and 3214JN) was not doing 117 VAC
(they where doing 12 VDC and 24 VDC respectively). While Papst isn't all there is to fans
they are usually a good benchmark on what is available.

Come to think of it... I have a bunch of big nice Papst 9950 lying around ;O)
A little bigger (119x119) and eating 230 VAC but good for CFM 68,9 so almost fit. ;O)

Cheers,
Magnus
