Ah, College! No idea where I got this info from, probably frantic Googling at the time. I made this because I was worried my laptop (a MacBookPro11,3) was overheating when booting into Fedora. Not sure if that was true at the time, I do vaguely remember seeing machine check errors at one point (not sure if it was in this cycle of installing Linux on my MBP or an earlier one, though). Who knows if it was actually overheating, could have just been me looking for problems or that the fan curve was different under macOS. I think I had installed Fedora around this time to mess with building IBM's OpenPOWER firmware, which was, for some reason, very exciting to me then.
