Yea, the 12V fans don't move nearly as much air as most 120 volt
fans. If the repeater is on emergency AC power it will make life
simpler to use the 120 V fans and run them all of the time.
If you know that it's likely that you will be running on emerency
battery power, then I would use 12V Blowers with the required
filtering and a thermal switch of your own choosing.
