I am looking for advice for the following problem: during rendering some 3d noticed unusual behavior of iStat Menus. Tested it with yes> /dev/null and both iStat Pro and menus. I am getting kinda weird temperature readings, it shows 77C and suddenly jumps to 86C and in a moment to 76C then 89C and the hotter it gets, the bigger the range of those jumps. Tried different update timings, same stuff. Didn't notice such behavior before, however don't remember when looked at the temp last time. Can it be faulty sensor or it is just the way it works?
