Freezing iMac Issue Due to Hardware?
They cite one user who had their video chipset replaced on their iMac who found that the problems had disappeared.
This and other reports provide increasing support for beliefs that the lockups and related symptoms are caused by excessive heat inside the all-in-one chassis.
While this remains speculative, it could mean that no software solution will be able to repair the issue. A similar but less publicized issue has affected early owners of the ATI Radeon X1900 video card for the Mac Pro. Some have noted these issues have become more prominent under Mac OS X 10.5 (Leopard) due to its increased dependance on the GPU.

Overheating ATI cards FTW. Apple chooses cost over quality. Consumers lose.
A thin machine is great, but only if it works properly. :cool:
The lesson is the same as always!
Never buy a Apple revision A product!!
I purchased the Rev A Intel iMac in January 2006 and never had a major issue with it. My only thought would be that Apple should have used the MXM format for the video subsystem in the new Intel iMacs as this would have made repairs much easier and cheaper for video related issues e.g. now. Has anyone tried using Temp Monitor to observe heating issue and compare those to the stated limits of those components from the manufacturers? Almost ever component inside the new iMacs have a thermal diode that can be measured.
I'm all for Apple's minimalist design philosophy, but this is a good example of possibly sacrificing function for form. Yes, "thinner is better" in Apple's eyes, but at what cost? Do desktops really need to be as thin as possible? Personally, it wouldn't bother me at all if the iMac was half an inch thicker in order to better offset any overheating issues which could have adverse effects such as this.

This info has been on these forums for many days now. Read the iMac forum :)

Early MacBooks also had heat-related issues, though it was more of a shutdown than a freeze.

Never by Rev A products from any manufacturer. (if you care)
