On the computer I've tested the lm_sensors package on, I have an asus a7a266 motherboard which has the as99127f hardware sensor chip. Many of the calculations in the example sensors.conf file provided are obviously inaccurate. The two which I have seemingly been able to improve are the cpu temperature and cpu fan speed. As simple as these calculations are, they definitely coincide with the bios's readings, throughout a broader range of temperatures and fan rpms. compute fan1 @ - 3000 , @ + 3000 compute temp2 @ + 30 , @ - 30 Once again, just as you state in the example conf, it's guess work, but this sure does seem to be a lot more accurate than the computations that were thrown in there. Hope this helps. -- John
