I believe you. I am having a heck of a time with the GPU temperature. Versus water temperature at 34C and ambient of 26-27C , GPU Temperature, GPU Memory Junction are +30 (70C) , GPU Hot Spot is +50 (80-90) (!!) at 400w. I used to be +20-25C at 520W but it has degraded significantly. If I bump up to 520w now and any kind of overclock, my GPU Hot Spot Temperature goes "runaway" meaning it increases and doesn't stop til the drivers crash. Coolant stays at 34C though, so its not a loop capacity thing. I'm kind of baffled, mostly annoyed and debating going back to the hybrid so I don't have to deal with this.

Go to Optimus PC and purchase the Kingpin 3090 3MM Fujipoly thermal pad. This is a full coverage thermal pads for the rear of the card. Then tear down your card, clean it up perfectly and re-mount your block. Take your time and confirm proper die to block contact. My Tjunction on the memory hits like 57C maximum.

Sounds like a paste issue if you know your pump has adequate flow. Stumbled across this... ( https://i.imgur.com/4LotOuI.png)

I saw your vid before, thanks for the tips. you asked earlier in this thread and I don't think I saw the answer - what size pads did you use in VRAM area? 2mm? Did you end up using pads or the putty in the wells? If pads, what size? Thanks

I'm going to guess vertical mount. Paste tends to run out over time.

Nothing impressive about that. An undervolted 3090 Kingpin that’s still hitting 40C at sub 300 watts is pretty rough. The card is consuming a maximum of 287 watts. And the GPU is still hitting 40.5C. That isn’t very good.

I think my vram pads are preventing good contact . This is what I'm dealing with right now. Only the Hot Spot Temperature is very high. It must be a die/block contact thing right? I think the Hot Spot can be GPU or Mem but if the other temps are so low, how can it be Mem? Anyway.. just venting now. I'm going to try telehog's pads setup in 2mm in front.

Evga stock pads are 2.25MM for the front and 2.25-2.75MM for the rear. The OEM KP hydro copper thermal pads are of very good quality too.
Just use 2MM for the front, and you’ll be good to go. You require the full coverage rear thermal pad. This greatly reduces overall temps.
3090 Kingpin hydro copper should be 48-50C maximum even with like extreme 600-650 watts of continuous power consumption.

Thanks for the feedback. I did 2mm Thermalright Odyssey 80x45 sized pads on front everywhere. Instead of TG Hydronaut, I used EVGA frostbite 2. Its possible I got a counterfeit batch of thermal grizzly. I think doing all of the front pads at the same time helped. Contact is much much better. My Hotspot and Memory Junction are about as good as they have been since the card was a hybrid but the GPU is better by about 3C. But I still can't get close to your numbers on Memory and Hot Spot, you probably have a good card :) Most importantly though, the Hot Spot temp doesn't "run away" with a stable OC. On the back, only snag I ran into is that I didn't have enough 3mm to redo everything perfectly. I have to get another 2 sheets for the backplate. Kingpin mounting pictures are elusive so for better or worse here is mine. If anyone has any notes, please let me know. Thanks again all, very much appreciate it.

You know Optimus PC sells the custom cut Fujipoly full rear-coverage thermal pad for the 3090 Kingpin. And it’s only $38 dollars right? It is custom made, Fujipoly quality, 3MM thick, and very soft. This is what gave me the temps I have. These thermal pads are amazing. The GPU temps, and memory temps are bottlenecked by how hot the back of the GPU runs. If you don’t cool down the back, it’s not gonna work out as well. Here is the link. When you use the this full coverage rear fujipoly pad, it totally changes the Hydro Copper. It’s the exact dimensions of the 3090 Kingpin. Buy the pad, and re-do the entire thing. Also, use Kryonaut Extreme (Pink), or Kingpin KPx (Blue) thermal paste. https://optimuspc.com/products/replacement-gpu-block-3mm-rear-thermal-pad?variant=39401788768339

elbramso btw. the best delta t water -> gpu I could get was 19C @ 520w
I believe you. I am having a heck of a time with the GPU temperature. Versus water temperature at 34C and ambient of 26-27C , GPU Temperature, GPU Memory Junction are +30 (70C) , GPU Hot Spot is +50 (80-90) (!!) at 400w. I used to be +20-25C at 520W but it has degraded significantly. If I bump up to 520w now and any kind of overclock, my GPU Hot Spot Temperature goes "runaway" meaning it increases and doesn't stop til the drivers crash. Coolant stays at 34C though, so its not a loop capacity thing. I'm kind of baffled, mostly annoyed and debating going back to the hybrid so I don't have to deal with this.
Go to Optimus PC and purchase the Kingpin 3090 3MM Fujipoly thermal pad. This is a full coverage thermal pads for the rear of the card. Then tear down your card, clean it up perfectly and re-mount your block. Take your time and confirm proper die to block contact. My Tjunction on the memory hits like 57C maximum.
Here is a video I made. Because people were literally saying I was lying. https://youtu.be/e5vE-YEKT-k
I was one of the people^^ simple because u got better results than 90% of all other HC Kit user out there. And still I don't think it's just the rear thermal pad that makes a difference of 5-10c delta - that just doesn't sound right. My rear vrams are actively cooled and the temps are super low but still my gpu core to water delta is ~20c @ 520w and 25C @ 600w... My mounting is not the best for sure but it all started with this block! Maybe the blocks differ a lot - so there as a variance of good vs. bad blocks... dunno BUT I'm done with this block.

Finally got the backplate pad Below is how it lined up with the backplate out of the package. I squared it up with the GPU mount holes and matched up the rest as I could. I trimmed the obvious overhand and made it fit nice in the end. Unfortunately forgot a pic when i was done. Unfortunately, no major improvement in temps either... but the runaway Hot Spot temperatures are definitely resolved. 20x PR run results below. Coolant temp 34C peak Tdelta's GPU +20C GPU Memory Junc +36C GPU Hot spot +40C Good enough but basically the same as the hybrid. Mem/Pwr/GPU are consistent with previous temps. Block performance is good but not amazing. Kind of a bummer after all of this but the card/block looks really cool vertically mounted and it does hold a +1000m/+100c/+121%p clock with everything I've thrown at it so I'll take it I suppose! Have a great night all.
