Even the small rackmount switches we use (Catalyst 2900XLs) make quite a 
bit of noise from the fans, and these are comparatively quiet.  3coms 
are appallingly noisy (i'm sure some of them would get environmental 
health round if you ran them in your house).

I haven't bought a new switch in quite a while though (I got a job lot 
of catalysts a few years back), so I'm not surprised some of them are a 
lot quieter now.  I expect some of them use far more heat-efficient CPUs 
than the ciscos (the 2900s have 486s iirc).

I'd still be wary about running /anything/ fanless in a rack though - 
when you've got a rack fully populated you can get some nasty hotspots 
from surrounding equipment.

And obviously some switches really make a *LOT* of noise:
