Does running gpu under heavy load and highish temps reduce lifespan?

Manufacturer says throttling begins at 83C and it's safe up to 94C

My question is that most games I play now on medium or higher easily push the temps to 82C and gpu load to 50-70%. I can run most games in the low 70s with vsync and the like.

Would continually gaming at higher temps reduce the lifespan of the card overall?
