https://www.techpowerup.com/298858/possible-custom-nvidia-rtx-4090-cooler-features-13-heatpipes With a typical graphics power (TGP) of 450 W, and power limit of 600 W, the upcoming NVIDIA GeForce RTX 4090 will be one hot GPU if not cooled really well. We don't expect a single 2-slot air-cooled RTX 4090, and even 3-slot could be close-to-reference, leaving 4-slot to be the standard (at least every custom RTX 4090 leak we've come across points to a 4-slot design). Twitter user "wxnod," behind spectacular leaks of ZOTAC and GIGABYTE graphics card boxes, is back with pictures of what is possibly the cooling solution of a custom-design RTX 4090 (or RTX 4080). The cooler features multiple aluminium fin-stacks skewered by as many as thirteen 6 mm-thick copper heat pipes. These pipes don't make contact with the GPU, but rather a copper vapor-chamber that serves as a base-plate for the GPU, and possibly memory chips surrounding it. Be prepared for one huge heatsink for this GPU.

A majority of these heat pipes won’t be touching anything in particular, so what’s the point? Why wouldn’t they be stacked if they are attempting to draw heat from one pipe to the next? Maybe there will be a mid plate on these cards to contact some of the heat pipes, but that doesn’t make much sense either.
I'm willing to bet there will be a plate soldered to the pipes and that would spread out the heat a little more. Or maybe this is just a ploy to get folks talking about the new cards, free marketing lol
I updated my post above. This is going back and forth between VideoCardz posts and techpowerup posts, and leaving out images included in said links. There is a vapor chamber between the heat pipes and core, but for some reason that was left out of the post. The video cardz link that was posted also shows exactly which card the cooler belongs to rather than numerous posts about each section of the card. It was all bundled nice and neat into one link, but not shared that way.

cool? .... time for factory 420mm x 45mm radiators  asking a lot from MB, to hang all the weight off of it, they should come with Vertical case mounts or Upright (end) mount, to stand card on end & riser cable

Maybe they will come with a fold out adjustable kickstand, that is rigid instead of being a wire like the e-leash?

AIB's need to step up and give us more water-blocked options for 40 series.
So many of us are just going to pay the money for GPU's with these humongous coolers just to have them taken off and shelved to collect dust. Such a waste!

If the card photo is real, I'm sad to see there's no SLI connector.

No kidding. Going to take time to see who designs good full coverage waterblocks too, and not just blocks that cool some components but not others. For a card that expensive I want everything cooled so there will be as small a thermal cycling range as possible. A vapor chamber combined with a crazy number of heatpipes. So glad I was already upgrading my radiator to a MO-RA3, that GPU by itself is going to saturate even a thick triple 140mm radiator.
 Have water, will cool.
