13 ODROID C2 USER MANUAL
Heatsink
Electronic components all generate heat while operating, and
different components generate different levels of heat. Some compo-
nents do not require any cooling, while others do. Complex compo-
nents such as the ODROID-C2 processor may reach temperatures as
high as 85°C. At high temperatures, the processor will throttle itself
and operate slower so that the temperatures of components do not
continue to increase. The ODROID-C2 comes pre-assembled with a
black heatsink.
Heatsink attached to the ODROID-C2
Heat transfer from components to the surrounding air is related
to the surface area available to transfer heat to the surrounding air.
The processor of the ODROID-C2 provides a relatively small area to
dissipate heat (approximately 1cm x 1cm). The metallic heatsink is
much larger and is therefore able to dissipate more heat into the sur-
rounding air than the processor itself.
Temperature Measurement
To help verify that the heatsink is effective, it is useful to get tem-
perature readings during operation. The processor’s built-in sensor
can be used for this. It would be ideal to have the processor working
under a realistic load. It is assumed that your unit has been through
the initial setup procedure and is running the latest ofcial Ubuntu im-
age from Hardkernel.
First, install the sysbench utility needed for the test:
$ sudo apt-get install sysbench
