is
controlled
by
temperature,
configuration,
and
software.
Actual
noise-emission
values
might
be
different
from
the
stated

depending
on
the
number
of
fans
and
the

of
the

Note:
These

were
measured
in

Institute
(ANSI)
S12.10
and
ISO

with
ISO

Actual
sound-pressure
levels
in
a
given
location
might
exceed
the
average
values
stated
because
of
room
reflections
and
other
nearby
noise
sources.
The
declared

indicate
an
upper
limit,
below
which
a
large
number
