-\b0 Yes, that approach is even better and could make your machine running cooler, when you are at higher loads. BUT: I did not take this route for smcFanControl, cause it has some risks. Adjusting the fan speed to CPU temperature requires you have a program running in the background (e.g. a daemon) that adjust fan speed continuously . If that program ever crashes or becomes incompatible cause of a System Update (or the readouts of the temperature sensor get inappropriate) , the fans could get set to a wrong (too low) speed and this could probably damage the machine. In addition to that the fan-control-logic is quite complicate. An intel mac has about 10 temperature sensors, that are continuously read out and are used for monitoring and setting the right fan speeds. So it would be "not so great" to read out just the CPU temperature as a foundation for the fan-controlling.\
