It won't matter how well you lap the cooler, after 2 min on Firestrike Extreme stress testing it will be at 110C hotspot with a decent overclock and the card will thermally throttle for the rest of the test. The card was designed to run this way, like it or not. If you can get it stable enough to pass the FSE stress test, you will be fine for daily use and it will rarely hit over 100C in any games. With at least 3 cards now, with a properly lapped cooler, the settings end up around 2000-2100Mhz, 1150-1180mV, and 1200-1250Mhz using the reg mods with 99% power limit. This also depends on your tolerance for fan noise and the cooling in your case, but a fan speed around 60% to 70% seems fairly effective.
If configured properly it can be used for testing of sustained performance and powerconsumption - and thus heat generation.

For example - the graph from yesterday is no longer true as the paste cured a bit. Now it shows 62°C GPU 93°C. Tjunction.

The only important thing is that Tjunction has to stabilize well below 110°C where throttling kicks in.
