Installing the IOH Cooling Fan (Optional)
If your system application requires more cooling than that provided by the IOH passive
heat sink, you can add a fan to the heat sink by using the included IOH fan and
mounting bracket. You can connect to the board’s 3-pin IOH fan header to power the
fan.
To install the IOH fan, follow these instructions:
1. Observe the precautions in "Before You Begin" on page 27.
2. Attach the fan to the fan mounting bracket (Figure 17, B) using the four screws
(Figure 17, A) and nuts Figure 17, C) supplied with the fan. Make sure that the fan
airflow is down as indicated by the arrow on the body of the fan. Slide the four
legs of the bracket over the heat sink fins and push down until the bracket “clicks”
into place.
3. Attach the fan power connector to the IOH fan header (Figure 17, D).
