Probably won't make a difference one way or the other. In theory, more heat could reduce the lifespan of the chip or more speed could reduce the lifespan of the fan, but the differences are so small and chances are they'll both be working fine long after the card is obsolete. 78 isn't obscenely high and the default settings are usually fine. Usually video cards only run into heat problems under load. Most video cards will shut themselves off before they can be damaged by high temperature. As far as defects go, it's more common for memory chips to fail than the GPU itself.
