Heat Dissipation Design
The LaCie Big Disk ’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 dissipate heat outside the casing. Because of
this advantageous feature, heat is taken away from the internal
drive, keeping it safe and prolonging its life and reliability.
As
a consequence, it is normal that the external casing is hot
to the touch.
Please make sure that the vent on the back-bezel
is 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 included rubber feet on
the under side of your drives (2). This will allow for some air-
flow 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 , Big Disk USB or Big Disk Extreme with
Triple Interface drives on top of each other (3), especially if
these drives are turned ON simultaneously. When stacking two
drives (or three), environment temperature should not exceed
30°C.
Smart Fan Technology
The casing alone is a great way to dissipate heat without 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 have a thermo-regulat-
ed “smart fan”, which activates when the heat inside the casing
reaches a certain temperature. The smart fan adjusts automati-
cally to changes in temperature.
