Doesn't look like:

Only temperature is going up:

>-835: envstat | grep degC
      temperature:     44.000                                degC
           TEMP_1:     47.000                                degC
           TEMP_2:     47.000                                degC
             TMP0:     44.000                                degC
             TMP1:     47.000                                degC
             TMP2:     36.000                                degC
             TMP3:    107.000                                degC

It's quite "fesh" here today w/ open windows so no forced powerdown until now...

But I can see a similar effect (temperature going high, but not above ca. 98 
degC)
when XFree86 has something to do - for example heavy scrolling while a build.sh
is running...
