There's two temp sensors one is in the VRM itself, but some boards have an analogue DCDC which is why they may not show every statistic.Uski brought this up the other day as well in this thread, and here post#65;

The reason you haven't had much of a comment from me is the only time time I have to check this thread currently is via cursory glances whilst on public transport, and even then the reception and a tiny mobile screen isn't favourable.
I wouldn't put solder to your boards if you value warranty btw.
In that post Uski is referring to the Amps, voltages and ON/OFF statuses that the digital DC/DC modules output. Not temperatures. Like you say they likely have a temperature sensor but that's likely only for the flags kill-switch mentioned.
Notice that in some of the screenshots people post of Bertmod, one can see the temperature sensor information but no DC/DC detected (certainly the analog ones like you say).
I understand it might be hard to give anything other than the straight answers you believe in while keeping track in a phone. Sorry about complaining about deferment to authority. There is quite a bit of that here nonetheless and I feel I got dragged into this collective temperature sensor discussion/investigation. But do tell us about your conditions now. Will you be employed by KNC? Staying in Sweden for the November batch? Will you get a place to sit rather than your phone?
