Not that this helps the OP, but I plan to try the NoiseMagic NMT-3
inside a cabinet:

I'll route a 3-pin 12V cord through a PCI bracket and out to the fan:

The following page shows how the fan will ramp up from 5V to 12V
depending on the temperature (NMT-2 scales from 30-50 degrees, NMT-3
28-42 degrees Celcius).  Many folks cut and extend the thermistor as
needed.
