Note:

In

this

computer,

fan

is

controlled

by

temperature,

configuration,

and

software.

Actual

noise-emission

values

might

be

different

from

the

stated

values

depending

on

the

number

of

fans

and

the

speed

of

the

fans.

reported

in

with

ISO

exceed

the

stated

because

of

room

other

nearby
