It's software. Assume nothing. While a decent program, it has limitations set on it by mobo manufacturers. They keep changing how they work. The temps are read from buss addresses, but what's one address on one mobo can be entirely different on another. TmpIn0 could be mosfets, Northbridge, socket, or even some obscure microcontroller. TmpIn4 on my pc reads 255°C, TmpIn6 reads -125°C. Both physically impossible for a mobo under anything close to normal circumstances.
If it's really worry some, the easiest method of checking is by using a thermal camera to check for the really hot spots, or a laser thermal sensor will do the same job, many electricians will have one. If you do find something physically reaching 112°C, you have an issue, but even taxed boards generally don't have componentry that'll go over @100°C at best. Some mosfets being the exception.
