Speedfan & HWMonitor both show high NB reading

[specialDFX]

Research tells me that speedfan is basically not to be trusted, but what about HWMonitor?

The reading in question is TMPIN1(HWMonitor)/Temp2(Speedfan), which is about 93°C at idle.

Best I can tell this is a reading for the northbridge.
My board is MSI 785GT-E63.

Touch tested all the heatsinks I could find, and the one I suspect to be the NB is quite cool to the touch. The one located directly under the GPU is slightly warmer but barely.

Hi specialDFXIn,

Hardware Monitor, if Aux is being read from an unassigned input, then just ignore it. In SpeedFan, Aux can simply be disabled, and therefore ignored. My Aux temperature is currently 17c, which isn't possible, since ambient is 25c. I've seen it vary from -19c to 127c, which means it's an unassigned input from the super I/O (Input/Output) chip on the motherboard. It's a common anomoly.
