Thanks for the input.  front to back airflow...  I already have some
holes in the back of the cabinet so I'll see if I can install the fan on
the front side.

bit of an aside:  I added a module to my app that uses the cpufreq
library for interfacing with the cpufreq kernel module.  So far all it
does is keep a slow default speed and it ups the speed to full blast for
10 seconds when it's time to print a receipt so that the postscript
rendering happens at a reasonable pace.  This is working pretty well.
The acpi thermal_zone module is reporting 36C now after a few hours of
operation.  After I install the fan I imagine it should start reporting
peak operating temperatures.
