Hell my current card 1900xt hits 93c at times, and it has a fan....So fanless I'd say that's pretty good, if it's designed to take that heat cool. I don't think in the test they even had it IN the case, case was open and not closed case like most would run it. Bet its warm as all hell then.
I do dream of water cooled silence though.....god how great would that be.
