I recommend using DC fan because it's much quieter than those AC type that sound like an aeroplane in your living room.[/quote:b9fa1f3e93]

not all dc fans are quiet. those high speed dc fans are noisy. it all depends on the rotational speed of the fans.
for dc fans, those that consumes 140mA or less are quiet.
