Judging from the OHM source, it looks like some Asus boards have AUXTIN connected,On Sat, Apr 28, 2012 at 03:04:51PM -0400, Martin Suchanek wrote:

others don't. -60 degrees C suggests that there is nothing connected to the sensor pin.
Open Hardware Monitor source code, http://open-hardware-monitor.googlecode.com/svn.

I don't see CPUTIN on your screen shot. I only see "CPU" and "CPU socket", but I don't see
anything suggesting that those report the temperature as measured on the CPUTIN pin
of the NCT6776F. To know how the values reported by the AI suite map to board sensors,
it would be necessary to see its source code and/or configuration files.
