So I have finished the assembly of my 3080 Ti today but I am not so happy with the temperatures. The delta is jumping immediately to 15C after the 1st second of full load and constantly climbs close to 20C. i have seen reviews showing 8-10C delta for this block, do I have a contact issue? This jump start from 25C to 40C in the 1st second is really unusual, I never had this on my past cards....

(I'm using an external radiator in case of confusion ;) ) 

I am 18-20C delta over my water and that appears to be the norm. My memory is 55-60C max. 
 
What is your temperature over water?

After 1 hour of gaming GPU was on 50C, memory at 51C and PWR at 51-56C. Delta over water as said 15-20. I will try this trick to tighten the screws again after the card has been warmed up. maybe this will help, otherwise I will repaste it with Kryonaut.

I'm already using Kryonaut and getting the same temperatures as you are. I don't think you can improve that much unless you use liquid metal. My census have shown me that multiple people have the same results. 
 
I think that EK has the GPU mounting pad a few micro meters too short so it's not making the best mounting pressure. That being said, I have spoke to a number of Hydro Copper people on reddit and they are getting similar results. I believe Optimus is the only block that gets around 10C delta over water. Is it worth the extra $200+? Up to user to decide. 

Understand. I was just wondering as I had a 3080 MSI Ventus before, the Bykski block managed 13C delta and the Corsair around 15-16. expected EKWB to be the best… i will tighten the screws after warming it up and let it be as it is…

Ah, well the Ventus is pulling only 320W https://www.techpowerup.c...tx3080-10240-210308-1, the 3080 Ti FTW3 pulls 450W. Linearly scaling this, is around 18-20C. 
 
When I'm gaming in APEX, Warzone or Assassin creed Valhalla and drawing 350W, I am 13C over water, which is close to your Ventus. 

Current build with the 3090 ftw3 waterblock and active backplate.

Bricked my first 3090 ftw3 with the regular standoffs. Took the standoffs out (received the revised ones from EK but decided against them) and gpu has been working great. Now, I have the active backplate. No issues. Memory temps down 15-20c. Gpu, on air would hit 80s. Now, it barely hits 60-65c on full load.

Maybe EK's pads are too hard. Has anyone tried replacing them?

I've thought about using putty, but I feel the EK pads when compressed right do a good job getting memory to 55-60C.

What if softer pads get worse memo temperatures, what is worth it then? Lower core or lower memo temperatures?

I might do liquid metal on 9-12 months. But I want to test on the winter and see if there even is a boost bon worth chasing.

I still think it's the waterblock boss being a few micro meters off. The EKWB Strix block performs pretty well from what I hear with the same pads.

Softer pads tend to get better temps due to them conforming better around the chip. You would definitely get better mem temps using Gelid Extreme's. At least I did on my Corsair block. About 12C. And they are very soft. I doubt putty would perform any better.

So even if the Gelids are softer, should I use the same thickness like the original EKWB or should they be thicker? 

Same thickness.
