I hung up and took my card apart and reapplied the tim and when i tried rebooting my computer there was a pop and my card blew a verry small amount of smoke will this be under warranty or did i break their already over heating broken card ?
I assume you don't have the little piece of paper about Warranty information that came with the card anymore? If you do, that should say what voids your warranty and what not. You can also check xfx site if they got a online copy of the warranty terms, or even call them. It really depends on the manufacturer if they "allow" taking off the heatsink and change the tim. Some do, some don't.
You probably did something wrong when putting the heatsink back in place as JTHMfreak said, or you may have put too much tim so it spread to the electronics causing a short circuit or something, causing a sensitive component to pop, or the card just happened to die at the same time of a manufacturing mistake or something, which would means it goes under warranty. Modern cards throttle automatically when they go too hot, and shuts them self down automatically when you are about to reach the critical point, so without voltage modifications and so, you can't "overheat" the card just by running games and such.
