Cooked my graphic card yesterday. Same iMac model. Incredibly WORKED! (a bit less than 10' at 200 °C, no evident smell but can't be sure of temperature since I have a gas oven with analog thermostat).
Put new thermal paste and made some stress test in the night (http://www.geeks3d.com/gputest/). Temperature during stress test went up to 100-105 °C for few instants, then fan speed increased and temperature stabilized between 80-90 °C. Playing a game does not stress the GPU so much (bit over 70 °C).
So, happy for now. I saved the 180€ for a professional replacement of the graphic chip.
