That is not correct. the end of the card has a blanked off heat sync. the air intake is sucked in around the fan

You're thinking AMD, this is Nvidia.

I give everyone, one. If I comment, I know. So before correcting me, fact check first.

It is blanked off in the middle of that heat sync. While it does add to the thermal mass and case fan airflow would help with cooling a bit, The card shroud is not an open tube with a fan in the middle. Towards the end of this video, he shows how the fan shroud is shaped to block off the back of the card and direct air toward the outside of the case. if you look at the heat sync, you can see the blanking panel that is molded into the heat sync that blocks air flow.

Just think, if it was an open tube with fan in the middle, how can you make sure that the air is always exhausted out of the case? You cant, it would also exhaust air into the case out of the back end as well but those cards do not do that. all the air is exhausted outside of the case

So my request went ignored...

Is the video card, in your video, a 980ti?

No... This forum lives and dies by people willing to exchange information, not beliefs.

Its not my video and no the subject of that video is a 1080, however, the axial fan used in all of these blower designs draws in air around the inner silver circle you can see in the photograph and ejects air in 360 degrees. Without ducting to force the air to go in the direction you want, which in this case is over the main heat sync and out throug the silver grills to outside the case.

On your photograph, on the smaller rear heat sync at the top right of the photo, look closely. There is a line that runs across the direction of the fins, perpendicular to the length of the card. That line is solid material that blocks off airflow. If it wasn't there, the axial fan would be blowing air out both ends of the card instead of maximizing airflow over the GPU to the fans left side.
