I am aware of fan control software for my Imac. But I was curious about the default factory temps that will cause the fans to spin up. Does anyone have chart or formula that shows at what temps the fans increase their RPM.

I have saw temps of 135F on the CPU today and still the Fan RPM is around 940. Just wondering at what temp does the cpu have to get before the fans kick up.
