As I remember SpeedFan doesn't use profiles or anything to save the info, it just does. I don't use that feature on any of my boxes (SuperMicros), but it does retain the names of everything fine. On the few AMD based machines I've built for others, speedfan did retain the under/overclock and fan speeds after the first setup. The auto functions always worked fine with a chipset selection. Only the charting functions are not persistent.
