How To Fix Mac Overheating Problem

There is a simple solution to overheating problems with your mac, and that is don't run a screensaver. It may be funny, but the simple reason is that mac's screensaver runs using the graphics video card and this causes your mac to heat, but not overheating. From researching on Apple forums, they say that it is normal and will not cause any damage to your computer. But, if you are concerned, this is the simplest solution:

• Go to System Preferences->Desktop & Screen Saver->put the slider to never start screen saver.
• If you want to lock your screen, just click Hot Corners->Put Display to Sleep.

Note: When playing video games, this also requires using your mac's graphics video card, so that explains it.
