How do you know that "CPU temp is at least 55 degrees C"? 38 degrees C
is possible if the CPU is idle and has an efficient fan.

For voltages, you need to adjust some lines in sensors.conf:

    label in1 "Vram"
    label in5 "Vagp"

    compute in3 2*@ ,  @/2
    compute in5 @, @ # or remove the line altogether
    compute in7 2*@ ,  @/2

    set in0_min 1.7 * 0.95
    set in0_max 1.7 * 1.05
    set in1_min 2.6 * 0.95
    set in1_max 2.6 * 1.05
    set in5_max 1.5 * 0.95
    set in5_min 1.5 * 1.05

That should give you much better results. Don't forget to run "sensors
-s" after you edited the configuration file. Also make sure you edit the
it8712-* section.

You can also comment out the "ignore  vid" line, and use vid to set
in0_min/max.
