I thought that since we are away from Ataris, we don't need a fan control anymore, anyway:

Better are controllers that increase the speed, the higher the temperature is.

Indeed but I am not sure putting a thermistor (or whatever kind of sensor you have) on contact with the chip would produce the same results as the built-in thermometer. On the other hard if you can get temperature readings in software level you can send them to a micro controller (Arduino?) which will control the fans accordingly. I think we are a bit offtopic though :) .
