[hpsdr] Pandora Fan Orientation?

[John Ackermann N8UR]

We haven't done any serious testing on airflow, but it intuitively seems 
the right thing is to have air blowing into the cabinet, so that it's 
directly hitting the LPU heatsinks.  However, intuition isn't always 
correct, so it would be interesting to hear from anyone who really knows 
this stuff.
