Presumably, you wwant to avoid "right off the PS" so that
you *won't* have to modify the PC *or* dangle pigtails out
of the case.

Can't you just tie 5V DC fan to the power pins on the USB
connector? Or, do you want some sort of "intelligent"
thermal management? (note that you can buy variable
speed fans that have a thermistor in the airflow and
adjust their own speed.
