Unfortunately, this is a rather common situation. > I have similar sensor chip in one box (w83697hf), no fan speed control, turns out desktop AMD Sempron doesn't have CPU power idle therefore CPU temp varies only a couple degrees on load --> no point having fan speed control, thus mobo make didn't wire it. If CPU is running at ~50'C there's not much fan speed reduction can be done, in my situation I put the PC box under the desk to reduce the fan noise :o) Grant.
