CHAPTER 4: Thermal Specifications
Embedded Bezel
This section lists empirical temperature data from measurements taken while using
the embedded bezel.
Results show certain components running hotter in 320 mode than 220 mode. The
HiFN (compression chip) runs slightly hotter, and the Hydra chips (read channels)
also run hotter. Both of these trends are to be expected as the data transfer rate is
increased from 11 MB/s (220) to 16 MB/s (320). However, most other components
show very little difference between the two modes.
