check to see if the core is touching the cooler.
That is alarmingly high. Due to the 90nm architecture of the core, the heat release should be lower than the 6800 series. I get 60 on full load.
You should be getting sub 55 on full load. Make sure cooler is touching the core, or put some ceramique or AS5 on it. If that doesn't do it, RMA the sucker.
