The aux fans come on due to a pressure switch that is located in the drier. If the pressure exceedes 260 or so the fan(s) will come on. The older model cars had a green switch that came on around 280 or 300 but the switch has been updated to the red one that is the 250-260 range. It made a big difference in how cool the engine ran with the A/C on too.
