It's pretty normal for the chips on the middle dashboard to run slightly hotter than the other two, the difference in that picture is a bit over the average but nothing concerning to me at least, I have seen far greater variance than this, it could also be caused by something blocking the airway in the heatsink around the sensor that reports 82c.

if this was another gear I would advise him to clean it, but since this is a T17, I rather not touch them if they work, I remember a bunch of heatsinks coming off when I used an air blower to clean them, it's like they installed them using saliva instead of solder.
