Apparently, the game's menu screens aren't framerate-limited. This means that when there's nothing else going on, your graphics hardware renders the bejeezus out of those screens, causing nasty overheating problems. The fix is easy, requiring players to add the following lines to your "Documents\StarCraft II\variables.txt" file:

frameratecapglue=30
frameratecap=60
