As an example: I recently ran a git filter-branch --index-filter on a fairly large repo, with the index-filter command…

int i;
i+=1;
or
int i;

As i can see, with this software you can set the fan speed. So, if you set it to low, theCPU temperature will grow really high and it can burn in likely 1 hour - is this possible or not and why ?
Thanks.
