I got the card today, first thing I did was replace TIM. I had to repair the card, before that it was fresh from a RMA, so no dust at all.
I don't think it should be that hot at 100% fan, its only 185W TDP, my 260 was 175 and had a crap cooler and never went above 75.
Good airflow, two 90cfm fans up top on my radiator, two 70cfm intakes blowing directly towards the card, one right under the card's fan.
I shudder about the VRM temps too, the 55nm GTX 200 cards don't have temp sensors on them, or cooling.
I had three of them and all of them ran hot. Replacing the TIM may help, but I am a person that believes you shouldnt have to do that. It really sucks when you spend hundreds of dollars for a product that they didnt perfect before releasing it. One of the reasons why I changed to 5870's, cause they run much cooler. I do miss some features from Nvidia, which is why I am looking at going back with a GTX 580 X 2. LOL
