Log *complete* S4MAX'23 / World's smallest 4090 build: Brickless 5l S4Mini, 4090FE, 7950X3D, 800W, water cooled

[metapath]

@morj Thank you, I'm yet to find good source with the psu mod walkthrough.

I got my hands on affordable corsair waterblock for the 3090. Annihilator waterblocks are really scarce, althouh I have seen the later versions pop up on auction history aggregators.

1. Which waterblock (am4/am5) do you think I could get as a stand-in?
2. Which would you choose as a base for customizing acrylic top cover?

PSU mod is described in the original @petricor thread, that's what I used to make my replica.

Hey @petricor with the release of the 9800x3d maybe you can do an update to see how much the loop improved with this new CPU undervolted.

Waiting for something bigger

oh boy, I already see a 9950x3d + 5090 build lol

How is this 1 million ppl if the scores you told us about were all in the three thosands maybe I missed something but 34k/5 isnt 1 million

Petricor! My brother, Idk if you've known but I've been a longtime fan PPL admirer of yours..., and I'm wondering... are you going to update your amazing build with a 9800X3D & 5090?

So with that said... are you updating this build... are you retiring from SFF?

Nah... no retirement in sight here! But why settle for 9800?! guess I'll need to come up with a better plan for cooling though! That's not an update anymore, but a redesign... will be exciting!
First step is rather annoying though: Getting hold of that FE kit early on... happy to pool interest if anyone has an inroad into reliable sources!

I don’t really see how a waterblock for the 5090FE would be feasible. The PCB isn’t even connected to the PCIe slot, it uses a ribbon cable.

The main gpu pcb is connected to the pcie slot directly by a connector. The displayport and hdmi connectors are connected by a ribbon cable though. What a water block would have to do is emulate the attachment points that the stock cooler has. So a water block would need to hold all the parts more or less where they are as it is. A greater challenge than previously but not insurmountable.

It's actually an amazingly well-suited case for an sff water block: May imply to design one though! The modular layout has the potential for the design of something much smaller than a 1 slot card - now that's really exciting. And I see an opportunity for aftermarket mini-riser-cables that come in the form of a tiny ribbon cable that goes between the daughter board connectors , with the daughter board going straight into the mother board's slot. And if you run video through an onboard dp-over-thunderbolt or usb4 interface like I do, there is a good chance the card will work without the dvi connector board altogether. The result will look radically different and much smaller than anything we have seen so far - very exciting days!

I can't wait to see what you do with this

I haven't yet seen anywhere that shows the dp/hdmi output pcb closely but it is possible that it can be disconnected and the card still work. The one or two glimpses I've seen of it had it with only a couple passives and possibly a small voltage regulator. Can't say definitively though. The one thing to be aware of when water blocking this gpu is that it is unlikely to be as thin as the 4090 since it has comparatively tall inductors that are on both sides of the pcb. At least for myself, I am not going to be trying to get my hands on one this generation; the thickness is extremely critical for me. Not to mention that it is over my power budget.

Valid point - it does have some vertical prominence!
Unfortunately I just missed out to the probably seven 5090fe that Nvidia were offering on their UK website this afternoon - just did not hit refresh fast enough in the 5 seconds that mattered- that means that for the time being, and whilst resale prices come down (£5k on ebay - yay!), I'll have to resort to 3D models.
So: Should anyone have been lucky enough to get hold of one and dares to take it apart, I'd be extremely grateful for dimensions or a mobile phone 3D scan!
