It's still not a smart Idea to run a completely passive system though. If you don't exhaust heat the air in your case will heat up and it can damage/reduce the lifespan of your components. Besides, it's always nice to hear some sound to assure that your computer is ok (unless you're doing studio work, which still shouldn't pick up noise if you use quiet enough case fans).

I have never been bothered enough by fan noise (unless busted) to run the risks of passive cooling. In fact in my current system I have 4 fans I think, sometimes in look through the window in the case to check if they are actually running at all they are that quiet.

At least on full load, the side and rear front coolers will still run at lowest speed and maybe will keep this card cool enough instead of his own cooler and "take off" when the fan is in full load.
PS: For the 6850 SCS3 with a 80mm fan, lowest RPM given by MB and open case, 30C ambient it hardly gets over 60C on full load. The fan is put with rubber pins at the bottom of the case and in a midiATX case (i think) the distance isn't very big between card and fan. This distance is better for low temps then the attached version of same cooler as i noticed. And with a 12mm fan on low RPM put in front and side its a bit cooler too.

Putting such an enormous badge on top of a passive heatsink is a stupid idea. Whoever came up with that should be fired.
