2.7.2 Operating Temperature and Temperature Control
The maximum and minimum operating temperatures for the IOWA-MARK are listed
below.
Minimum Operating Temperature: 0ºC (32°F)

The system is shipped with a preinstalled heat sink. When running the system do not
remove the heat sink. If the heat sink is changed, make sure thermal paste is placed on
the bottom of the heat sink to facilitate improved heat convection from the CPU surface to
the heat sink.
