Is that on idle, or on stress? Try stressing it (use "stress -c 2"
because you have dual-core, and run "watch sensors" or "xsensors" to
monitor temps. They should usually be below 80C when the CPU is at
100% load - 80 to 90 is borderline acceptable, but not ideal. above 90
is overheating)

sudo apt-get install xsensors stress

For the git repository, this would probably require manually
maintaining the scripts for each run in the bisect.

For testing purposes, it doesn't matter since those blobs won't be
loaded on your system (unless you have the Intel wifi or something, or
some device you inserted that might use them). Just make sure to
switch back to linux-libre afterwards.
