Heat Dissipation Design
■
The LaCie Big Disk Extreme+'s metal body is ideal
for naturally dissipating internal drive heat. Its unique
design actually draws heat away from the internal drive
toward the external casing. The casing absorbs heat and
will take advantage of its large surface to further dis-
sipate heat outside the casing. Because of this advanta-
geous feature, heat is taken away from the internal drive,
keeping it safe and prolonging its life and reliability.
a consequence, it is normal that the external casing is
hot to the touch. Please make sure that the vents of the
back-bezel and front-bezel are not obstructed so that
there is a natural airflow across the casing.
Upright, Stack & Rackmount Configuration
■
Heat dissipation is maximized when the drive is in
the upright position (1). If you have several LaCie drives
stacked on each other, please remember to attach the in-
cluded rubber feet on the under side of your drives (2).
This will allow for some airflow between your drives so
that the heat dissipation can work effectively - especially
if your LaCie drive does not include a fan. LaCie does
not recommend stacking or racking more than 2 Big
Disk Extreme+, Big Disk USB or Big Disk Extreme
with Triple Interface drives on top of each other (3), es-
pecially if these drives are turned ON simultaneously.
When stacking two drives (or three), environment tem-
perature should not exceed 30°C.
Smart Fan Technology
■
The casing alone is a great way to dissipate heat with-
out the need of a fan. Therefore, currently, most drives do
not require a fan. Only the largest capacity drives may
need a fan. To find out if your drive includes a fan, please
refer to the item number and product datasheet.
Some models of the Big Disk Extreme+ have a
thermo-regulated "smart fan", which activates when the
heat inside the casing reaches a certain temperature.
The smart fan adjusts automatically to changes in tem-
perature.
