The OS has definitely control over starting the fan or not. After some OS X upgrades, I remember reading comments from Titanium users saying that the fan was starting more often then with the previous version. However, like I said before, if the sensor reporting the temperature is defective, both GaugePro and the OS will display whatever is reported. If the actual temperature is more, then the fan would not start and you would think that the temperature, like you noticed, is not out of line.
