What my brother probably meant was that if you graph out performance
vs. temperature, you'd probably get a flat area at the max performance
level. Looks like he's saying that the hottest you can run it, and get max
performance is 50 degrees C.
That part of the (original) message might not be all that relevant
for here... It's more like FYI stuff...
