One way to fix an overheating graphics chip in an iMac

Outstanding, extremely helpful comment. I used one of these fans:

Slap a velcro ring around the inlet side (I put the "loop" on the fan, and the "hook" on the iMac), put a horizontal strip top & bottom on the iMac itself, and the USB power cord is just the perfect length, even on a 24" iMac.

If the overheating problem has already damaged your GPU (so you still get video artifacts and kernel panics), you can disable Quartz Extreme:

To test whether or not this will actually help you, try booting in safe mode. If it runs perfectly fine that way, then disabling QE will help.
