Hi Curt,

Based on the schematics I've sent you, it seems that there is some 
miscomputation.

So right now I could suggest a different computation for:

compute in3 -@*(1+(232/10)), -@/(1+(232/10))

The calculation for the 5V is OK, but then again... in2 is not 5V. So 
now I'm guessing in6 is 5V, so change your in2 labels and computation 
to in6.

As a last challenge:
How are your system temps displayed? After all, they are connected 
through thermal resistors on SYS_TMP and CPU_TMP.

Kind regards,
