Actually, several content creators I know constantly complain that the X1900XT overheats. Even a new card in a new machine that is clean can still overheat. I just lost a Mac Pro due to this. Thank God I paid for the Apple Care.

On a different note, I found an article a while back about the X1900XT. If you have noticed on other threads here, we refer to three versions of this card. Well on a subtle note is a temp spec that is slightly different between the cards.

Chances are you have an older card like the one I had that just failed. My newer X1900 is fine. The new one being replaced is also a newer version.

There is a difference.

A note to any of you who've had system freezes. If you have gotten strange pinwheels of death or reboot required lockups, chances are, this is why.

Keep a can of compressed air in the roadcase. Also invert that can every now and then to cool off your GPU.
