HI BAP
Those are reasonable for that card.
Mine both are the same way.
Your times per frame are very consistent so I wouldn't much worry about that. That card seems to run in the 70's and reaching 80 every once in awhile will not hurt it.
We had an ice storm here on Friday, overnight, and left a good half inch on the car and the sidewalk and porch. I chose NOT to go out and try to walk on it for fear of falling and messing up my back. I waited till later when the temps rose and the ice started to melt.
Hope all is well out there with you and mrs. BAP!!!!
My best,
