Installing an MCH Heat Sink Fan (Optional)
If your system application requires more MCH cooling than that provided by the MCH
passive heat sink, you can add a fan to the heat sink by using the included MCH heat
sink fan mounting bracket. This fan mounting bracket is designed to accommodate a
40 mm x 10 mm or 40 mm x 20 mm, 12 V dc fan. You can use the board’s 3-pin MCH
fan header to supply power to the MCH fan.
NOTE
An MCH heat sink fan is not included with Desktop Board DX48BT2 and must be
purchased separately.
To install an MCH heat sink fan, follow these instructions:
1. Observe the precautions in "Before You Begin" on page 27.
2. Attach th
e fan (Figure 16, A) to the fan mounting bracket (Figure 16, B) using the
fasteners (Figure 16, A) supplied with the fan. Slide the four legs of the bracket
over
the heat si
nk fins (Figure 16, C) and push down until the bracket “clicks” into
place.
3. Attach
th
e fan power connector to the MCH fan header (Figure 16, D).
