1- 1.3V is always the max safe voltage
2- 90C is max safe in my eyes.

I read that 1.25 was a bit of a danger zone. Either way, I would try to avoid that high a voltage. Chances are that a stock cooling unit ain't gonna like that voltage redface.gif

And you'd be more likely to care about VRM temperatures more than core temperatures since the former rise at a much faster rate than the GPU itself?

Sort of asking for my own purpose.

Where did you read that? 1.25v is the default voltage of boost cards. And like Flashfir said, watch the vrm temps. That's what actually fries when you hose your card.
