Arctic Cooling's Accelero S2 passive cooling solution is compatible with Nvidia's new 9600GT card, at least with the ECS 9600GT version.  

Arctic Cooling has showcased an ECS card that will use Accelero S2, which is Arctic Cooling's well known passive cooler. The only drawback of this cooling solution is that the card is a bit wider, but this is the price you have to pay for a completely silent solution.

It is definitely nice to see that Arctic Cooling has a way to passively cool the 9600GT.
