I wouldn't particularly care about temps I got when running a benchmark. You can always find a test that will lead to high temps.
I don't see a temp above 71 degrees in the pic you posted.
That pic shows video fan speed at only 54%. It doesn't appear to be working very hard. I'd expect high speed fans to be noisy.
You have to research whether the video card temps you actually experience while gaming are "too high".
Fans on video cards can be replaced.
At any rate, a PSU change would not be high on my list as a way to reduce temps.
If your research determines that you video card gaming temps are dangerously high, I would look somewhere other than the PSU:
changing video card fan
changing video card
improving overall case ventilation
You may have a poorly designed case with poor ventilation overall, but changing these things might not have a lot of effect on video card temps. The video card heatsink and fan are the most effective ways to change video card temps.
