I've put about 12 hours of gaming in on the new setup. I'm still missing a wire and a couple fans I want to upgrade the EVGA hybrid radiator with, so I don't have my case side panels on yet, but right at the moment it's running incredibly quiet (only real noise is the GPU radiator fans when they kick on and I don't have them super high so they're not loud at all...will be even quieter once the glass panel is on).
 
I only messed with my OC for a few minutes. Ended up getting a cold right after Christmas, so it has limited what I've felt like doing at night, which is usually my play time lol. Ended up with a new highest score for all but single-core for myself on CPU Profile. It seems that 6.1GHz on 2 cores wasn't stable, so I might actually get some better all-core scores as I think even with 5.8GHz all-P and at least 4.8GHz all-e I only hit 83C on the hottest core for a second in the max-threads test. The other tests were in the 60's or colder, but they're very short. If you look at the comparison between that and one of my previous best runs, you can see that the average clock speeds were up by 162MHz and temperatures were 7°C lower on average. I'm still not 100% sure on how the adaptive voltages with the V/f curve are supposed to work on this board, as there are three different 5.8GHz values I can set, and I can give them all different values...Currently just have all three at +0 lol. -25mV on 51x and 54x.
 
The two games I played (7 days mostly) were pretty light on the CPU and one day it hit a maximum core temp of 52°C lol. I think it was under 150W the whole time though.

Outstanding results. 

I finally got all my fans and cables in, so I've finished putting it back together.
 

 

 

 
The fans go under the top panel that the radiator sits on now, so it was a nice test of the disconnects. Just disconnect three cables and two tubes and lift the whole rad/pump setup right off the computer. Easy-peasy (other than the weight lol).
 
I tried to get a close-up of my pump tubing as I had forgotten that picture last time.
 
I wasn't sure where the water temperature sensor was going to live when I started this and it ended up just sitting on the PSU shroud. I keep the case so dark with minimal RGB lighting that you can't even see any of the wires or tubing under the GPU and it just glows nicely. I had shined a light at the computer just to take that second picture above, so you could see inside, but normally it's pretty dark in there (which is why I like the Dark Base Pro 900 case and went with the "Dark Water" and now "Dark Palimpsest" names). It's subtle, and even though it's tall as can be and looks monstrous when you really start thinking about what all is there, it's very quiet now and nice to sit next to.
 
Also, the fans I put in (Silent Wins Pro 4 120mm on the GPU radiator...holy crap they move some air). I cranked it up to max just to test it out and while it does make some noise at 100% (just air-flow noise, I can't even hear the fan motors really), it pushes a lot of air out the vents at the top of the case. I was really hoping that radiator swap would work out and so far it seems extremely promising. Let's see how temps are after some hours of gaming with all the panels on the case (I have had it fully open the last couple weeks).

Very nice setup!

Cool upgrade!

A fantastic upgrade. Well done!

Oh...where did you come from?

 
I happened to see it show up as "in stock" on Best Buy the other day. Just randomly. I've checked at complete random every now and then since launch and have never seen it. It was for pick up near me (a small town area where I'm surprised our Best Buy is even able to keep the doors open)...I was thinking this whole time "no chance they ever get a 4090 here" lol. I ordered a Heatkiller block for it and a new bequiet! power supply. The rest of the parts should be here this week. When I picked up the card, I asked the guy at the register if he's seen many of these. He was like "NO! This is the first one I've seen here. How long did you have to wait?!"
 
I'm going to fix my pump order while I have the loop drained. I accidentally ran it so that the one pump pulls from the system and pushes into the reservoir and the other pump pulls from the reservoir. Once it's running, it seems fine, but there's some distance (and height) between the pulling pump and the system. This makes there be a chance for air pockets to develop which are not so good for the pump. I'm going to make it so the res-pump pushes into the other pump. So two pumps directly in series pulling from the reservoir instead of relying on pulling up a tube from the system below it.
 
More updates soon.

Another excellent upgrade. 

Pretty awesome man!

I installed the 4090 to make sure it works before doing any water block work. Seems like a huge step up in benches. Haven't gotten any games in yet, but after doing all the work to take out the other card, (also doing BIOS update, vBIOS updates to air to sell the other GPU, taking the case apart, DDU,...etc. lol) I only had so much time to test things. Did a few speedway runs, TSE, played with Superposition a bit and called it.
 
Just testing the card (no side panels on the case):

I think I'll end up moving up the whole motherboard tray (which also lifts the rear fan and everything). I used to need room for a thick push/pull-rad setup up there and now there are just fans.

Observations: Everything is CHONKY. the card is chonky, the adaptor is chonky. I'd have to bend the crap out of it to fit my side panel on. It'd help if I routed tubing differently, but I was just doing a test here, so I left it. I can't imagine how obnoxious the STRIX cards are.
 
Completely stock Speedway run: 9918
Did a quick +150core, +500mem run: 10213
Added a bit more core and cranked up the power slider (not that it did much): 10389
Didn't have much time to play with it before moving on to test other things. I basically just wanted to make sure the card functioned correctly before doing any mods and wanted to run through several benches quickly. Also curious what thermals looked like with the power draw on this card.
Time Spy Extreme: 18816
I had my CPU at my 24/7 settings, not my max-bench settings, so I wasn't breaking any records there, but the GPU ran +285core and +750mem. It crashed at +300core and I didn't play with pushing memory at all. That said, pushing my CPU a bit for a previous score only added ~200 CPU points lol. I think my best with the 3080ti was 11184 total. While I'm showing TSE scores, here's a 4080 laptop with 13980HX: 9105. I don't remember if I had it in the manual-maximum mode or just the high performance mode right under that, but compared to my 3080ti desktop, it really isn't bad.
 
I'm curious to see what the 4090 does on water though... 
 
Speaking of which, my water block came in, so this'll be the next process. I'll do the changeover all at once so I'm definitely waiting for the new PSU to arrive too. Sneak peak:

 
The power supply I ordered is the be quiet! Straight Power 12 1200W. It's platinum efficiency, handles 200% excursions on the GPU line and has the single cable for the GPU, which will help in my case dramatically. Also, $279 was a lot more palatable than the $419 for the Dark Power Pro 13 1300W. The ripple is a little worse on these, but they're still a really well built supply according to the reviews that exist so far so I'm hoping for the best.
 
The saddest part of all this though...after this upgrade, the motherboard will be the only EVGA part in my desktop. I've also recently dropped the EVGA mouse I had as I got sick of dealing with its issues. I still have the keyboard, but just those two. I used to have the PSU, GPU, Motherboard, AiO, keyboard, mouse...lol. oh well.
