Great, trac is good.

It does, but ...

I believe it's set to Auto, though I'll have to check.

I'm less worried about such a small skew.

Right, this is a non issue.

w83627hf-isa-0290
Adapter: ISA adapter
+12V:      +4.92 V  (min = +10.82 V, max = +13.19 V)       ALARM
-12V:      -1.59 V  (min = -13.18 V, max = -10.80 V)       ALARM

I'm mostly concerned about these values, they are not skews ...  are 
they just mis-named 5V and 1.5V readings?
