The FE cooler is honestly the most impressive part of the 5090.

30% more performance with 30% more cuda cores and 30% more power.

👍

Thinking like an engineer, you may not need 58 different tools. If all the bends have the same radius, they could just use the same tool, but stamp the different parts a different number of times for each piece. You can calculate the deformation at a given pressure for the fin material, so for example, the least bent fin gets 1 stamp press, and the most gets n+58 stamps. The process becomes longer and more involved, but the cost of the tooling could remain within reason.

Great video, very interesting, I always love your work!

14:08 PCWorld had an interview, with an Nvidia rep, confirming the curve's purpose matching your suspicions. Good catch!

[RoyNotHome]

It makes me very happy to see Joe here and that he's landed on his feet with you.

Only reason I can think of for someone to a) employ an ex EK waterblock designer and b) get them to do an accurate CAD model of 5090... is to make future 5090 waterblocks

1:32 that "whatever" came from a man who is completely done with A.I marketing.

[EcoAcid]

RTX 5090:

30% faster than 4090 (ignoring framegen, pure raster)
30% more power consumption than 4090
30% more expensive
30% larger die size on the same process node

Such innovation, much wow.

1:19 graph is all we were waiting for.

[alanbixby]

PCWorld has an interview with a NVIDIA product manager yesterday which confirms many of the assertions raised here; the fins are concave to optimize for the pressure delta of the passthrough fans, the angled fins are to redirect air to make a "shield" to deter cannibalistic looping air. Definitely worth a watch.

[qqekzss]

Tell me Joe is doing all that work because there is a Grizzly FE block in the works, don't waste this man talent . By the way we need an entire WC lineup from Grizzly !

[Kappa_mi]

As Nvidia is becoming more inclined to thinner cards third parties are producing bigger cards than ever

[brunoyuji]

Usually the dimples, bends or louvers would be to increase turbulence and thus increase the air side heat transfer coefficient. The concavity of the fins may be to try and increase flow velocity through the center by increasing the resistance on the edges (since there is more fin surface area).
Honestly the thermal design of this card looks amazing and a real treat for thermal engineers. I hope I can get my hands on one to actually see it in person.
I wonder if they have brazed the heat pipes to the vapor chamber or they have them directly connected to the chamber. Can't wait for you or Steve to cut them open!

[theheadone]

regarding the stamping tool, I doubt that they made 52 different stamping tools, I would say it's more likely that it is stamped with varying pressure with the same tool to get the different bends. Still an expensive process as they need to keep all the plates organized for assembly though, even if they only used one tool.

[bsoul]

As someone who works in a metalshop with laser and punching machines, what they most likely did to get the decreasing profile in the fins, is use the same tool but use less force while punching in the profile. It's possible they could use some Ertalon (nylon) in the die to have some support when the profile gets smaller. We use wheel forges in CNC punching machines that roll over the plate to make shapes like that (but much longer) and then lower the pressure so it will flare out the profile into the metal sheet and makes it look better.

Good to see watercool Jesus found new home.

[wesamycin]

Now that the EK Joe is working with Der8auer there will be waterblocks for 50xx from ThermalGrizzly

When you do your review, can you show PCIE 4.0 VS PCIE 5.0 I'm on a 5800x3D so would like to know thanks 🙏
