One of them is an LM75, as I've told you a dozen times 
Don't mean to question your credibility Avenger as everyone knows that your posts are always fact based ~L)L~ but I would like independent confirmation of the device identity. For both of them.
If they are LM75 devices, then they are measuring the board temperature at their location and are not using a temperature diode on the ASIC. If they are some other chip, then they may be using a temperature diode on the ASIC chip.
Could someone please provide a nice close up showing these 2 devices ?
Just an FYI but It's _my_ credibility you have questioned.
I looked at the parts and reported here as asked.
I HAVE pics but will not provide to you.
Believe me or not, my day remains the same
YMMV
