after I updated iTunes, the machine turned off twice. Once while trying to see a movie in Plex and the other while watching vids and browsing. The only thing I could do was wait a few to turn it back on. After the second time, I thought I should see what the temps were because I remembered reading the machine would shut down due to heat. Took this not to long after normal browsing. The fans never rev up more than shown. I've downloaded SMC FanControl just in case.
