1.4. Hard Drive Heat Management
Heat Dissipation Design
The LaCie 2big’s metal body is ideal for naturally dissipating inter-
nal drive heat. Its unique design actually draws heat away from the
internal drives toward the external casing. This feature takes heat
away from the internal drive, keeping it safe and prolonging its life
and reliability.
As a consequence, it is normal for the external
casing to be hot to
the touch. Please make sure that the vents on
the back bezel are not obstructed so that there is a natural airflow
across the casing.
Vertical, Horizontal & Rackmount
Heat dissipation is maximized when the drive is in the vertical posi-
tion. If you have several LaCie drives stacked on each other, please
remember to attach the included rubber feet on the under side of
your drives. This will allow for some airflow between your drives so
that the heat dissipation can work effectively. LaCie does not recom-
mend stacking or racking more than 3 drives on top of each other,
especially if these drives are turned ON simultaneously.
Smart Fan Technology
The casing alone is a great way to dissipate heat without the need
of a fan, but the 2big comes with a thermo-regulated “smart fan”,
which activates when the heat inside the casing reaches a certain
temperature. The smart fan operates at two different speeds, and
adjusts automatically to changes in temperature.
