I have a mid-2012 Retina Pro (loaded: 16GB RAM, 768GB SSD, etc.), with annoying heat issues.

Whenever I'm doing anything GPU-intensive (games or CUDA simulations), after about 30 minutes, the chassis gets extremely hot (enough so that my hands sweat if hovering over the keyboard or typing) and the app in question either crashes with an exception, or silently exits. Of course, before that happens, the fans are running full speed.

(In this case, under Windows 7 via rEFInd.)

The game in question is Portal, which runs fine at full speed and resolution on this machine (not unexpected since the game is several years old), at least until it exits.

I'm guessing this is due to the video driver terminating the application to prevent damage to the machine, but I can't be sure.

Occasionally, even if not running that type of app - say, browsing the web or word processing - the machine will get very hot and the fans will kick in.

  1. Is this typical behavior for this machine, or something wrong with this particular unit?
  2. I've read that the cooling system has been redesigned in the new models. Is it effective enough to prevent these issues?

(Under OSX, I have the same issue on anything that requires the discrete GPU.)

Update

Specs:

  • Model MacBookPro10,1 (15" MacBook Pro with Retina Display)
  • Nvidia GT650M
  • 16GB RAM
  • 768GB SSD

  • The new cooling comes out on 3 ends. The original location and left and right of your keyboard. – Rob Feb 7 '14 at 18:49
  • @Robuust on my machine, there are vents above the keyboard (so it blows along the screen when open), and what looks like two vents on the bottom of the machine, on the left and right sides towards the front. Is this not the same as the new machine? – 3Dave Feb 7 '14 at 19:21
  • Can you add a picture of your Macbook specifications please? e.g. videocard etc. – Rob Feb 8 '14 at 10:31

I'd recommend you try the exciting new (and free) TurboBoost Switcher, which disables Intel's Turbo Boost. This means your MacBook Pro will overheat far less often. You can also boost fan speed preemptively with SMCMac or iStat menus.
