Nice! Happy to see some pics of a Dark in the wild.

The Z590 Dark actually tells you which M.2 slot is PCIe 4.0 directly on the board - no manual needed. lol
 

 
...and I don't even own the board.
 
Nice photographs tech brother! Your tower of cooling power is SWEET!

Now that's embarrassing.
Shows you how observant I am.
It's right there is his picture.

Here's my result from CrystalDiskMark:
 

 
Those numbers are ok, but then I ran the same test on my 570X rig (5950X) which edges it out on sequential reads and puts the smack down on random read/write compared to the Z590:
 

 
The 570X rig has dual Sabrent 1G NVMe 4.0 drives in it and I did the test to the D: game drive and not the OS drive, but I was not expecting that big of a difference, especially since the Z590 has a clean Win 11 install (both are on Win11).  To be fair, the X570 is running a 17% or so OC where the Z590 is stock except for memory being set to XMP1 gear 1.

Will be interesting to pit the 2 rigs against each other once the Intel rig has been tweaked.

I first upload the images to imgur and then paste those URL's here when clicking the Insert/Edit Image button.

I do see it.  Your reads are smoking fast!
 
Once you upload it to imgur, be sure to use the direct link as opposed to the image link, when you grab the URL to put back in your post here.
 
I captured your image and am posting it here:
 

 
So I got my 11900K running at 5.2 GHz on all cores and stable.  However, some of my cores are getting mighty hot:
 

 
Don't know if it is the "free" paste that came with the block, my application method, or the fact that I'm scared to tighten down the thumbscrews really tight since there is no backplate underneath the motherboard.
 
I'm comparing to the temps Luumi is getting at 5.2, which are:
 

 
So I'm as much as 14C higher than him on one of my cores:
 

 
Once I move the Z590 Dark into a case and add my AquaComputer controller, sensors, etc, I'll have a better idea about what's going on.  Given Cinebench R15 only takes 30 seconds to complete, I'm pretty sure it is just the thermal conductivity between the CPU and block that is messed up.

going above 5.3 needs avx offset 1 and avx 512 offset 1. if u run higher than 5.3 clocks on avx workload it will clock down to 5.3. this is an intel thing.

I think I figured out why my core temps were so high.  I had the flow reversed through the Optimus Foundation block.  It should flow in to the center and exit from the sides.  I'll be sure to reverse it once I get done putting everything into my Core 9 case.
 
That case just swallowed up that large Z590 Dark:
 

 
Other side:
 

 
Nest up will be mounting the dual 480's in the top rails.  I stole the AX1500i from my AMD rig and gave it the EVGA P1200, which should be plenty since that rig will just have a single 3090 and a 5950X is not nearly as power hungry as a 11900K.

It will be pretty tight once everything is in, trust me.
 
Each rad is setup like this:
 

 
Both 480's installed:

Oh my goodness! How much radiator surface area do you own? 
 
Wowie, you can certainly improve on my overclocking results. I'm only using a simple Noctua heatsink with a single 140mm Noctua Industrial fan.

Did he just say 3090s? As in plural? As in more than one? 

That looks like a really nice case to work in.

did you set the voltage manually on your 11900k? It seems like the voltage is pretty high for a 5.2GHz all-core setting. Mine doesn't get that high until 5.3+. I think it hits 1.460 at 5200MHz during the OC Robot run. 1.549V at 5300MHz. I currently have it set at 1.39V adaptive with a +50mV offset and -25% droop with ratio-limit set at 5.3GHz for 1-4 cores active, 5.2GHz for 5-6 cores, 5.1GHz for 7-8 cores. I can benchmark at 5.3GHz all-core, but for any normal usage I don't notice a difference at 5GHz or 5.1GHz from 5.3GHz, so I just leave it there to be nice and cool.

Impressive numbers!
 
Got everything wired and plumbed.
 

 
It actually does look mostly empty still, lol.
 

 
Aqua Controller:

 
The Thermaltake Core 9 isn't my favorite case given how huge it is.  I prefer open cases, but since I had this sitting in the attic and it has a 5 1/4" opening (very rare these days) for the Aqua Controller, I decided to use it for this build.  If I go hard tubing later, I'll definitely get a different case and I guess I don't really need to keep the display attached to the Aqua Controller, which will expand my selection quite a bit.
 
Cinebench 15 run is barely registering on the coolant temp graph:

 
The PSU definitely did notice the run however:

 
Core temps are much better now that the coolant is flowing in the right direction:

 
Guess I'm ready to drop in the 3090's next!

it looks like u have disabled ocp(u have maxed ocp). its better to keep it on for safety reasons for daily(default is disabling them, I know its confusing)
