As for +12V, the ATX specification says +5V should stay within +/- 5%.

I've updated the wiki page, thanks for your contribution.

Looks good :)

One possible improvement would be to set in0_min and in0_max limits, as
0 to 1.74 V is way too permissive. You should check the allowed voltage
range for your CPU and allow for a 5% deviance.

Also I see that the fan1 limit changed so I guess it is also
uninitialized. You should set it to something that makes sense for your
case fan. This would avoid spurious alarms and would also let the
driver select the right fan clock divisor so that you get the most
accurate readings as possible.
