Interestingly, the passive versions are smaller and lighter than ASRock's overclocked triple-fan Taichi models. While it makes sense for the overclocked cards to be bigger and heavier because they're being pushed to their limits, you'd expect the passive GPUs to have much larger heatsinks than the non-overclocked GPUs with triple fans. But, according to ASRock's data, the passive GPUs have a slightly shorter length.

We're looking forward to getting our hands on these passive cards, as we want to see how they compare against their active brethren. Although it's a shame we didn't get these cooling options at the launch of the 7000-series AMD GPUs or even the 4000-series Nvidia cards, one can always say, "Better late than never."

These are absolutely “passive” in the same way that there are passive Tesla and FirePro/Radeon Instinct cards. They depend on high active airflow through a server chassis to remain cool, they will not dissipate 300W through convection in a standard ATX tower.

I agree. These are not "passive" cards in that they are meant to work without any fans or no more then some minimal ambient airflow. Cooling systems like this use large widely spaced fins to allow air to move easily through them. This thing is a highly dense heat sink and requires a high amount of airflow through the length of the card or things will overheat quickly. It's clearly meant to work in a server type system where there are some very high speed fans directly in front of these cards with the airflow directed directly through these heat sinks and out the back of the case. They don't come with a fan because it's expected that the system will provide the fans, not because they don't need a fan.
