GPU Over 100c 2 weeks after applying Thermal Paste

I have a somewhat old ATI Radeon HD 6800 and I've had this issue where my GPU was over 50c when doing normal things (surfing the net, idling, etc.) and goes over 100c (115c was the highest) when I play somewhat graphic-intensive games (Guild Wars 2) even though I set the graphic settings to "Optimal". I changed the graphics to the lowest even, and the temperature still was around the 90-95c range.

Then we applied thermal paste on it, and the temperatures finally roamed around the 80-85c mark which is fine. 2 weeks after though, it was back to over 100c. The weird part is that the idle temperature is completely fine now (around 40-50c).

I'm kinda of worried because if this goes on, not only my GPU would die on me, but I'm fearful that the rest of my CPU components will to. Would re-applying thermal paste fix my problem, or is it time to buy a new GPU instead?

Dude you probably applied the thermal paste wrong... But if you're sure you did it right, stop pushing the card to much, 100c for a GPU is way to high and will kill it soon, lower the graphics the maximum as possible, if the high temperature persists, start using a resolution LOWER than your default monitor resolution, it will put more work to the CPU instead of the GPU

Thanks Niceguy and Natan.

Maybe the thermal paste is applied wrong. I think we applied the right amount, but spread it out instead. The GPU is spinning, but oddly enough it tripled the speed when my temp reached over 100c (which is understandable) but now that my computer is idle (around 45c), it's still spinning real fast (around 3700RPM).

I did try to lower all my games' graphic quality, and it was still pushing 100c. I'll probably stop playing those games for now until I fix the problem or buy a new GPU.
