I can say after using Gelid Extreme thermal pads, my temps are now 1-2C better than stock. (88C @118mh, 72c in Unigine Heaven)(Fans at 85%) Had to fiddle around with the sizes, but remember.. if you do go to change the thermal pads don't touch anything but the memory. The vrm and other components are just fine reusing the putty and luckily with an ftw3 card you can verify that by looking at all the temps. So when I changed my card over to a hybrid, I did 2 mm plus 0.5 mm on the memory and that did the trick.

Here's what my ghetto setup looks like. Noctuas and heatsinks scattered all over the back plate.. thanks EVGA! 🤦🏼‍♂️👍🏻

I have the same cpu/gpu 5950x & 3090 ftw3u, I went with ek's block and used 10 W/mK thermal putty from digikey's website paired with thermalright odyssey pads 12.8 W/mK and thermal grizzly kryonaut paste for the gpu. I wrnt from evga's stock air cooler for the 3090 to the 3080/3090 quantum vector block

Following Jufes tutorial fron the youtube channel "Frame Chasers" I only applied the thermal putty to the memory chips for my initial install and pads on top for the purpose of filling in the spaces between the chips and the putty forms around the edge of the chiplets and gives superior transfer of heat compared to just thermal pads. The thermalright pads are close to the same firmness as the blue ek pads(~3.5 W/mK) so I had zero issues during installation.

While I wait for the active backplate to come (sept) I am using ek's backplate for now with the stock evga thermal pads which I compressed before the install along with the blue ek pads that came with the backplate. I will use the same process for memory chips on the backside as I did for the front(die) side.

The results I've achieved are surprisingly good, really good actually. I'll post some pics below, the quick miner screen from nicehash corresponds with HWInfo, just an fyi.

Gaming @ 4k my temps are between 45°C - 52°C for the gpu while my VRM's and memory run cooler than mining. I couldn't be happier with my results and I'm excited to install my active backplate.

I hope all this information helps someone out and answers some of the unknowns that are out there in regards to ekwb block install. If you want a parts list of my build let me know.

Ambient temperature in my pc room is around 24°C - 26°C

Temps with mining with stock air cooler: GPU - 42°C
MEM - 90-96°C

Temps after ekblock install:
GPU - 35°C
MEM - 64°C

Why can't I share Imgur links to my pictures for my previous post? Is there a way I can show my pictures?

You can't post links until you have 30 post.

Oh ok thanks.

Following this thread very closely as I've been thinking of replacing the thermal pads, but seeing that stock numbers look better.

I went with ek's block

 
Is this the EK-Quantum Vector water block? I've been looking into this product as well. If so, which radiator did you pair with it?

Don't do it bro. Not worth the headache.

Assuming you mean the thermal pads aren't worth it? Leaning more towards the water block + active backplate route.

Yes it's the 3080/3090 ftw3 quantum vector nickel/acetal block.

Radiators are EK 360 PE and a EK 360 XE.

I cannot post links yet but my Imgur profile is aardougjess is you can find me on there you'll see my pictures I was trying to share on here.

I noticed everyone is putting the heatsinks directly on the backplate and not over mlcc / poscap capacitors.  In a guide somewhere else someone put a single, larger sized heatsink across the entire back side.  This would put more heat over top of the mlcc / poscap that previously was not there.  Is that an issue for the capacitors to have that heat over them or would that be acceptable operating conditions for the capacitors?
