overheating and shutdown problems when adobe flash runs?-Collection of common programming errors
There’s nothing you can do except complain to everyone you meet. Adobe pretends the problem does not exist. They blame websites for having settings incorrectly set.
Who in their right mind develops software that intentionally allows developers to set their software in a way that causes overheating. Even the beta version of Flash Player 11.5 continues to have the problem. It happens in Windows as well; it happens in IE9, Chrome and Firefox.
It would be nice if there was somewhere that everybody being affected by this problem could jointly protest Adobe’s irresponsibility.

Also, install a program that shows your computer temp and pause Flash until the temp starts. It’s a temporary help but at least in avoids having the computer shutdown or worse a fire.
