Despite the 4 80mm fans running at full speed all the time, the case gives
off little more noise than the hum of the fans doing their job. Maybe I
don't notice it much as my office at work is next to the server room and
that is LOUD!
Anyway, I'd say that this case is only a bit louder than my old mini-tower,
and with music on or when gaming it's not really noticeable. The only time
it's noticeable is when I'm just doing email or something like that and I
don't have any music playing.
