More Pictures of NVIDIA's Cinder Block-sized RTX 4090 Ti Cooler Surface
Back in January, we got our first look at the cinder block-like 4-slot cooling solution of NVIDIA's upcoming flagship graphics card (called either the RTX 4090 Ti, or the TITAN (Ada). "ExperteVallah" on Twitter scored additional pictures of the cooler. Its design sees the heat dissipation surface pushed to the entire thickness of the cooler, and ventilated the entire length.
The card's PCB isn't conventional—not perpendicular to the plane of the motherboard like any other add-in card—but is rather along the plane of the motherboard, with additional breakaway daughter cards interfacing with the sole 12VHPWR power connector, and the PCIe slot. This slender, ruler-shaped PCB spans the entire length of the card, without coming in the way of its heat dissipation surfaces. The length is used for the large AD102 ASIC that's probably maxed out (with all its 144 SM enabled), twelve GDDR6X (possibly faster 23 Gbps), and a mammoth VRM that nearly maxes out the 600 W continuous power delivery design limit of the 12VHPWR.

It's a halo product GPU so I won't expect sane pricing.
Still, it's a halo product. Expect a very insane price.
How much is too much?
It's as big as my Johnson.
It was occasionally scalped much higher than that - not because there were any shortages or large inrush of buyers, just because it was the only card in the new Ada line up that made sense, it had larger performance increase than price increase, as obscenely as this sounds, and the higher price kind of made lower end cards look better? It didn't work, warehouses are still full of unsold cards, revenue is still falling. Luckily there's forecast of large orders for AI, so gaming sector can go and find something else to do.

Can't wait for someone in a woodshop to run this one. I can imagine the Youtube videos: Dusting a 4090Ti, using a leaf blower on a 4090ti, fastest way to clean your 4090ti....etc.
it's not gonna be dust bunnies in there, more like dust caverns :D
