Thermal data for convection-cooling
with a heatsink assumes a vertical
mounting of the drive on a thermally
non-conducting surface. Heatsink fins
run parallel to the long axis of the
drive. When fan-cooling is used vertical
mounting is not necessary to guarantee
thermal performance of the heatsink.

THermal reSISTanCe
Thermal resistance is a measure of the temperature rise of the drive heatplate due to
power dissipation in the drive. It is expressed in units of °C/W where the degrees are
the temperature rise above ambient.
E.g., an drive dissipating 16 W mounted with no heatsink or fan would see a
temperature rise of 38.2C above ambient based on the thermal resistance of 2.39C/W.
Using the drive maximum heatplate temperature of 70C and subtracting 38.2C from
that would give 31.7C as the maximum ambient temperature the drive in which the
drive could operate before going into thermal shutdown. To operate at higher ambient
temperatures a heatsink or forced-air would be required.
