[lm-sensors] does lm-sensors pick up sensors that don't exist?

Many monitoring chips have multiple inputs and the motherboard
manufacturer does not always connect all of them. I have an Asus
M2N-SLI motherboard with an it8716 monitoring chip with three inputs,
but only two of them are connected.
Another possibility is that temp3 is connected to *something* in your
system, but the values that lm-sensors uses to scale the raw reading
are incorrect. Have you looked in the /etc/sensors.conf or
/etc/sensors3.conf for any information on your particular monitoring
chip or motherboard?

On my system, temp3 on the it8716 always reports the maximum possible
value, +127 C. I can guarantee (by putting my hand inside the case)
that nothing in my computer is that hot, so I have always just ignored
that reading. I suspect that either the chip is designed to report the
maximum possible reading if there is no sensor connected, or that Asus
wired the unused sensor input to ground, +3.3 V, or some other voltage
that makes it read at the maximum possible.
