First thing. The amount of paste is so excessive it's not funny. Second thing, the paste, like all other stock paste, regardless of hardware type, is dimpled.
Surely manufacturers know that perfectly flat paste would be better for temperatures and therefore longevity? Wouldn't it stop cards dying of heat related causes? Wouldn't that mean less faulty or dead cards, meaning less cards are returned? Wouldn't that mean companies wouldn't have to spend so much on replacing faulty cards?
After a replacing the thermal paste with a booger-sized amount of paste (less than a BB size), the card is now idling around 25c, and loads at about 65-70c depending on the game. That's much better, isn't it?
Moral of the story: Change your GPU thermal paste and get better temps! /captain obvious.
Not so obvious at first thought is that less heat rising from your GPU = less heat rising into your great dirty big air coolers that we love so much. Not really an issue on water or anything else though. But with air, it will help overall temps, even if only by a small bit.
Note on warranty: Many manufacturers state that changing the paste will void your warranty. I saw screw em, change the paste, and if you ever need an RMA, try anyway and don't mention it. See if they notice, or even care. Through all of my RMA's with XFX, Sapphire, Asus, HIS and other companies, they have never cared. What they don't know won't hurt them. (Note, not all the cards were mine, but many were from friends of mine who bought them through me, or they gave me the money to order it for them. I also changed the paste on all of the cards. Not thermal pads however)
You should have no excuse for leaving the stock paste on now, even with the stock cooler
