EPTCertain screens make your hardware work pretty hard
Screens that are light on detail may make your system overheat if cooling is overall insufficient. This is because the game has nothing to do so it is primarily just working on drawing the screen very quickly. A temporary workaround is to go to your Documents\StarCraft II Beta\variables.txt file and add these lines:
frameratecapglue=30
frameratecap=60
You may replace these numbers if you want to.

'Anyone else have StarCraft II try to melt their hardware? Blizzard admits that it's a known issue and has a fix for you.
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 Beta\variables.txt" "Documents\StarCraft II\variables.txt" file (nice catch, commenter LegolElf):
frameratecapglue=30
frameratecap=60
Good to know. Personally I would have appreciated a heads-up before my video card fried, but maybe this can save someone else from the hassle I've been dealing with since yesterday afternoon.

i have noticed in campaign my FPS jumping to 900 during load screens. Glad there's a fix for this.
EDIT: in the actual article they cross out the beta portion of the file path. This appears to have been an issue before official release as well.
