3.2 Installing the CPU Fan and Heatsink
When the CPU fan installation procedures presented here are
inconsistent with the installation procedures you obtained from the
CPU fan and heatsink package, follow the latter.
To install the CPU fan:
1. Apply thermal grease evenly on top of the installed CPU.
2. Lower the CPU fan to the CPU, then secure it using the
provided attachments or screws.
3. Connect the CPU fan cable to the CPU fan connector on
the SBC labeled FAN1 (see “Board Layout” on page 18).
CAUTION:
The CPU requires a chassis with an airflow inlet and maximum
internal ambient temperature of 60° C. An approved CPU heat-
sink and fan must be installed before using the SBC. Failure to
install a CPU fan and heatsink may damage the system host
board and/or the CPU.
