FYI, I have the O11d XL, with my bottom rad being the 60mm EKWB XE rad, with 25mm Uni-Fans on top of that, then 14mm hard lines running on top of the Uni-Fans.  On top of that is the EKWB Vertical GPU mount in the top most slot...
 
Everything clears by the faintest of margins.  I can slide a piece of paper between each of those things but really nothing more.  So your 54mm rad shouldn't be a problem.  

DHL just updated my delivery to today!!!

 So I cant get rid of a giant bubble in the corner of the block no matter the orientation of the OC.  MY fiancé thought I was crazy flipping my PC upside down. Below is a video of me moving the bubble by squishing a tube while the pumps is at 100%.  Any ideas on how to get rid of it?
 
Edit.... well it appears I cant post links so heres a picture
 
 
 

Rotate the card around so it moves toward the outlet and it should go out.  Usually I haven't had too much issue doing this in the past.

Is it possible to use the original backplate with the EK block? Unfortunately the EK backplates are not available for the moment...

Looks like the trick was rotating the computer when it was turned off.  All is good now!

Fantastic!

Did you use washers when attaching backplate or attach it directly to the back of the board?

Did you all of you have problems with the locations of the thermal pads on the black plate?  Are the pads touching on both sides fully or if there not full contact?

Are you talking about this? https://forums.evga.com/m/tm.aspx?m=3201194

Yep, that's what I'm talking about.  I'm curious if EK got the heights right.  Everyone that has used the Optimus water blocks has said they have exceptional tolerances.

Finally had an opportunity to take some decent pictures after the ekwb install.
 
The following are my updated stats with the ftw3 air cooler and ftw3 ekwb:
 
Port Royal Runs

1.081v (throttled down to 1.068) 1980core (throttled down to 1950) +0mem 70C
1.081v (throttled down to 1.043) 2130core (throttled down to 2070) +500 mem 74C

For my daily I have it set to 1.0v at 2130 core and 500 memory.
 
 
 
 

Thanks for the detailed information.
 
What software are you using for OC and Undervolting? What have been your highest scores so far in Port Royal?

Nice looking build - congrats.

You happy with the Cloud White coolant?

I have some waiting to use with my build - moving away from clear for the first time and really hoping it holds up.

I ran the cloud white myself for about 6 months before doing a maintenance. It left some gunk in the blocks and left a film on my reservoir. Went to clear. function/form.

For us with the 3090 FTW3, that active cooling backplate looks mighty nice. I hope they make it for our cards.

 
I considered attaching a CPU block to the backplate near the backside of the GPU location or several MOSFET cooling blocks to the backplate above the VRAM location.  It would be another excuse for me to finally buy a drill press. 
 
With my air cooled 3090 FTW3 cards and MSI Gaming X Trio card I had a 140mm 1600 RPM Noctua fan  blowing on the stock backplate to aid in cooling.

EK confirmed to me that they will be making the active backplate for our FTW3 cards. They could not give me a date though. I'd still get a drill press though. I mounted my card vertical (at least for now) and it has 2 120mm fans blowing on it from the bottom so it should be pretty good for now until I get the block from EK that I have on order and the active backplate eventually.

Thanks for the detailed information.
 
What software are you using for OC and Undervolting? What have been your highest scores so far in Port Royal?
 

MSI Afterburner. I've been waiting to use Afterburner since the Precision X1 software is pretty terrible when it comes to undervolting (i really don't want to deal with moving a bunch of dots around), but only Precision X1 can control all 3 fans properly.
 
When I was testing lower voltages with the air cooler, I would have to toggle back and fourth between both applications. For whatever reason, I would do a benchmark run only to find out fan 3 wasn't running at all, or running at a different speed compared to the other fans, very frustrating.
 
Now that I have the gpu blocked, I can completely bypass Precision X1 and just use Afterburner. I'm hoping EVGA updates the Precision software and gives us something similar to Afterburner in terms of undervolting.
 
My highest score in Port Royal is 12745 with the 2175core and 600mem overclock. The run was with my 5.0ghz overclock on my 9900k. I haven't tried running my 5.3ghz overclock, I'm hoping to break 13k when I get a chance this weekend.

Thanks. This build has been going for the past 4 years. It's housed a 980ti, 1080ti, 2080ti, and now 3080. Went through the x58, x99, and now z390 chipset. Not new, but not old either. Looks better in person IMHO, I'm not a great photographer.
 
I've only used Mayhems Pastel White coolant since I started this particular loop, never used any other type of fluid. It has held up very well for more than 4 years.

I've never used Cloud White from EKWB, only Mayhems Pastel White.
 
I sold my 2080Ti in August and left my 9900k in my loop and patiently waited until I got the 3080 and EK block to tear everything down, clean, and rebuild. Mind you I never cleaned my loop until this past week, all I did every year or year and a half was drain the loop as much as possible and refill with new coolant. Been doing this for over 4 years.
 
Last week, for the first time, I took it all apart and cleaned everything with water and I was surprised that only certain fittings had a bit of gunk on them, all cleanable with a bit of elbow work. There was a tint of white on the tubing but no other discoloration or degradation. The res does leave a bit of film but it hasn't been an issue beyond looks.
 
I wouldn't use anything but Mayhems Pastel White after my experience with it and hearing from other people about other fluids they've used.

With a little modding you can use the original backplate of the 3080 yes.
