It is hard to make the kind of equipment quiet and for it to stay that way.

It's non trivial, but eminently doable. The problem however is
twofold: it costs two things in short supply on ISS - space and
weight, and it has to be designed into the equipment from Day One.

Long ago I've read an article about the (german) company designing and
manufacturing some of the air ducts for the ISS and they seemed to be
well aware of the problem -- noise reduction was high on the priority
list. But there're so many things running all the time there and when
you can not rely on warm air rising by itself you have to move lots of
air around all the time...
