I'd like to note that a PM3, with a full load of modem cards, will continue
to operate if you *DISCONNECT* the single fan (which is really there to cool
the power supply) and it will NOT overheat in an average room under those
conditions.
Control of overheating starts by being *very* careful about power consumption
to begin with.
Remember that you pay for every watt consumed *twice* -- once to feed the
machine, and again to remove it from the room. There is no such thing as a
free lunch, and every watt you consume in a piece of computer hardware ends
up in the room as heat.
