Step 4. Install the Exhaust Fan
We recommend that you install an exhaust fan in the back of the case. The
recommended case list is in Table 5 on page 79. If an exhaust fan can be installed in
the case, we recommend that you install one.
The exhaust fan must be installed in the rear of the case, drawing air out of the inside
of the case. The arrows in Photo 6 show the required direction of the airflow from the
fan.
The fan should be positioned as closely as possible to the location where the processor
module will be installed on the motherboard.
