After some experience with my corrected heat transfer I'm generally
between 62 to 70. I don't do any gaming so I guess I'm okay. We
turn the heat down a lot and room temperature seems to make a
measurable difference, more than I would have imagined.

I wonder if adding a slot fan to lose a few degrees would add anything
to the lifetime of the card. Probably lose as much or more on my
electrical bill.

Thanks for the comments. Helpful.
