Q: 13" Retina MacBook Pro - fans go crazy, computer slows down
This is a problem that began a few days ago. It started randomly when I started up the computer one day--there seemed to be no sign that this was going to happen beforehand. I started up the computer, and randomly, the fans rev to maximum RPM and the computer slows down to the point of becoming practically unusable. It's as if the computer is having a "seizure". Typically it doesn't last for more than a few minutes, but it keeps happening over and over again until I shut it down.
The computer doesn't actually freeze completely during this time--everything can still run and it can still shut down properly. It's just really, really, really slow.
I've tried almost every fix I could think of: I erased the hard drive and did a clean install of OS X, I did SMC reset and PRAM reset, I ran all the diagnostic tests, but everything showed "no issues found"...nothing has any effect. Every time I start up the computer, I still get this "fans revving/CPU slowing" problem. It's as if the computer is overheating except it's not actually getting hot.
What is going on?
MacBook Pro with Retina display, OS X El Capitan (10.11.2), null
