Thunderbolt Series User Manual 8HARD DISK HEAT MANAGEMENTHeat Dissipation DesignThe Thunderbolt Series enclosures feature metal bodies that dissipate drive heat. The large surface area of theheat sink casing absorbs all internal heat, keeping the drives safe and prolonging their life. Since LaCie's uniquedesign draws heat away from the internal drives, the external casing will be warm to the touch after extendeduse. Please make sure that the vent on the back bezel is not obstructed and that there is a natural airflowacross the casing.POSITION AND STACKING2big Thunderbolt SeriesIn most instances, the 2big enclosure heat dissipation will be maximized when it rests on the stand in a verticalposition.
