Is the SB-220 such that you could put two 110VAC fans electrically in
series and physically stack them? This would run them at reduced power,
which would reduce the noise, though I'm not sure how much airflow you'd
get from two fans in physical "series". I've used similar dodges to
reduce fan noise in computers and other equipment, and there it has been
pretty effective.
