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)
