Very interesting...i have the 011d with 3080ti hybrid and 360mm cpu rad.
I had better temps on the gpu setting the fans in an intake rather than exhaust.
about a 12c difference?
I have found best settings for me is a push pull intake and i get avg 60c.
Thoughts?

Unfortunately, I never tried push+pull on the hybrid kit, so maybe that was the reason why intake wasn't better in my case.

You have to keep certain hard tubes under 60C. Approaching 60C or even being around that range for a long period can cause the tubes to become malleable. 

 

 
"Temperature is a huge part of bending tube, so taking your time and trying to heat your bend evenly can save you a headache. PETG tubing begins to be malleable at around 62 degrees celsius, and melts at 260 degrees, so you have plenty of room to work with."-Thermaltake
 
All it takes is a fan failing and the water temperatures rising. This user here purchase new fans and something happened to them where they weren't working right. His liquid heated up and his tubes became malleable and that's what happened.

Ok small update.  I think the EK block I have is defective by being bent or something.  I have had 3 cards that work that I installed that block on and not one of them would work.  Removed the block and 2 of the 3 work fine.  I did find that trying to shoehorn 3 3090's in one case isn't going to work out.  I can barely work two in there. (and the way it sits right now would be the laughingstock of the internet if I showed a photo of the second card just kinda hanging out the side.)  It's terrible, but for the time being it works (Like crypto is on a hot as hell run so I want to get every nickel I can before it drops)
The third card is sitting here disassembled staring me in the face annoying me to death that it isn't running.  I think this week I'm going to pull my twin 1080ti's and install this card.  If it works my hash rate will go up by about 20 and power will go down a little.  I have to say though, the 1080ti's run virtually cold in comparison to a stock air cooled 3090.
 
As to temps right now.  I'm running the Dell 3090 at stock settings (this card does not react well at all to OC'ing or any tweaking.  It looses hash rate more than anything when messed with)  I'm running the EVGA FTW3 Ultra factory hybrid on stock settings with the Bykski VRAM block.  The factory water cooled radiator for the moment is still installed and is outside the case on it's own.  So both sides of the Dell card are water blocked and only the VRAM on the FTW3.  The CPU is also in that loop.  For the sake of data collection I put three puller fans on the upper radiator to see if it aided the pushers underneath.  Temp changed by about 1C.   For 1 C I'm not sure the additional power usage is worth it. (full disclosure this is on an open case.  Until I can work the 2nd card into the allotted space I'm having to leave the side panel off so that may change the function of the pullers)
The Dell card GPU is running 36C, the VRAM is running 72C
The EVGA card GPU is running 46C, the VRAM is running 80C
According to the inline temp gauge the water is running 33C.  
For what its worth, I think maybe the flow is to fast.  It shows a rate of 187 lph.  I haven't been able to slow it down as each time I try it simply doesn't flow at all.  A lot of this stuff is kinda in the early stages of me learning what works and what doesn't.  I added a valve to simplify draining but of course the valve ends up defective and without a cap on it it will leak.  Fortunately, leaks are one thing I have not really had to deal with.  I had one spot to the upper mounted radiator leak a couple drops over 24 hours, got like 1/32nd of a turn on the end and it stopped.
 
The biggest issue is simply space, or the lack of it.  These water blocks eat up a great deal more space than I had anticipated. I don't think there is any way humanly possible to fit 3 3090's in a single case, unless it is some sort of customized case made for massive cards.  I'm running on a Corsair extension cable and literally have the card supported by cables that I had tucked away previously.  It ain't pretty, but it works.  Function over form for now.

Sorry to hear you got a defective block. There's a lot of mixed reviews about EK talked about in these forums (a lot of good and a lot of bad), but I never really bought any parts from them so I can't comment much about their stuff.  
Yeah, I imagine it would be pretty difficult to fit three 3090s in one chassis, I can barely fit my one 3080ti card in my chassis (I had to buy a lot of 45deg and 90deg fittings and used pretty small tubing).
And yeah, I'm sure the 10series and even 20series cards would probably run a lot cooler than these 30series cards.
But your temperatures seem pretty good.
Not sure what would cause your pump to not be able to change speeds normally, there must be a lot of resistance in that loop, I guess, but not sure where that would come from exactly.
Having a valve is nice if it doesn't leak, otherwise cleaning the loop can be quite a mess.
If you don't have any plugs, they would be worth getting since they are only like less than $10.
I just use the plugs that came with my Corsair XD5 pump.
That's nice you how fixed your radiator from leaking.
Would like to see some pics once you get it all setup and running!

I just slapped the Optimus (and their XL backplate) on my Ti FTW3 after running on air waiting for it to come in. Previous temps were low 70s after ~7 hours of gaming (3840x1600, max settings, various AAA games). Fan curve was set to auto.
 
After Optimus block, same gaming session keeps me under 50. Cooling is with single 480mm in push/pull, EK D5 (Quantum Inertia unit).
 
With +120 and +700 overclock I also got a "Legendary" TimeSpy run and landed 4th overall in graphics score for all 10850K + 3080Ti setups (at least as of a few days ago).

Good stuff. After now 5 years of experience with loops, I will definitely never return to air or hybrid cooling.

Ok, after a small but recoverable disaster I have finished.  When I expanded to cover the second 3090 card I had bought what I thought was a three way junction.  Looking back at my purchases, I had bought two of them and they rang up and a pair of 3 way connections.  As it was late Friday night that I did this I seem to have been not quite as attentive as I should have been.  I installed the assumed three way in the bottom card that night and then came back in the morning.  Install the plug on one side, fitting on the other.  Finished putting it all together and activated the pump to fill the system.  And within seconds that first pump reservoir full of coolant immediately dumped out of the bottom of that fitting that turned out to be a 4 way.  I had missed the fact it had a straight through fitting as well.  And that sent a new EVGA 1300 PSU to the promised land.  So I replaced the PSU with the same one and moved on, aggravated at myself no less.  It's been running about 24 hours now, no leaks.  Both the dell and EVGA cards are front and back active blocks.  The EVGA card is lightly overclocked with -250 core clock and +350 memory clock.  The results are:
Dell Card  GPU 44 VRAM 78  @ 244 watts
EVGA Card GPU 48 VRAM 78 @ 293 watts
The system fluid is running about 39C.
While I was replacing the PSU I had removed a cover that hides the PSU and rats nest of wires coming out of it.  I probably could have left that cover off and fit the third card, however I decided that was just more than I felt the need to deal with all things considered.  Please keep in mind, whereas many who do custom loops are concerned with form first and foremost, I am only concerned about function.  Function over form is the way I have done this, so it was never intended to look pretty.  I did make a small attempt to at least create clean routings of the hoses and cables, however it was the least of my concerns in this build.  This is just a quick shot below (it's been so long since I posted a photo I only just learned photobucket has destroyed what they were when they started and want money for everything now)
 
Also, I decided to pull my two gtx1080ti cards and install the 3rd 3090 in the old machine I have that just runs as a miner.  The two 1080's were pulling just under 400 watts and doing about 81 mh/s.  The one 3090 pulls 295 watts (give or take a couple but always under 300) and does 110 mh/s so it only made sense.  Since the VRAM overheating is the whole reason I did a custom loop, I decided to use all my leftover parts to put a small loop into that machine.  I did have to buy another pump as I wasn't about to use that TT piece of trash I have laying in the box.  Talk about not well thought out and a pain.  The CPU has a corsair all in one cooler on it.  The EVGA 3090 FTW3 Ultra Hybrid has it's own cooler as well. Add another 120 radiator for the VRAM and it's overcrowded to say the least.  So since again, function over form is all that matters in my case, I decided to do a little goofy and mount the pump/reservoir outside the case with tubes running through holes cut in the back lol!  I added a photo of it below.  It has not had but like 1 or 2 or the LED systems hooked up so it's pretty dark.  However, it does not appear as efficient even with only the VRAM in the loop.  It runs GPU 47 VRAM 79-80.  The card is lightly overclocked as well at -250 +350 as well  So now my average hash rate with all cards included is about 325-350 mh/s versus previously with two 3090s and two 1080ti's running about 290 mh/s average but now using 100 less watts.  I realize that having the radiator and fans at the bottom is not optimal in the least, but that case is designed with the PSU at the top and there is no topside vent.  Since I used whatever I had left lying around to build it, even if it isn't optimal it was cheap!
It's been an interesting journey thus far to say the least.  Funny thing is many of the cashiers at Microcenter all said they had considered custom loops but were intimidated by the thought of it.  I won't say it was intimidating, though for me it never seemed necessary.  However having to cool that VRAM and not wanting to see the cards burnt out in a year due to high temps running constantly is what pushed me to do it.  Not really that hard, but very time consuming.

I feel your pain! It was quite a journey going through all of this. I hope I can call it quits now... Although my GPU temperatures over water is 20C... That can use some improvement one day... Just not today as I don't want to tear this whole thing apart. 
 
Port Royal running 20 loops. Keep in mind this isn't a crazy benchmark run with my case fully open, etc. Both runs were with normal gaming fan profiles as that was the point at the time. For me to see what the GPU would heat up to at its worse if I gamed on it.

Your setup looks amazing!  Did you just get lucky with the 12pm Friiday drops from Optimus.  I've been refreshing the page at 12p but I haven't been able to snag one yet.
 
Also, sweet pump/res :) I have the same one.  Its a cool piece of hardware.  I like how you plugged the temp sensor right into the port on the res.  I used a T fitting hidden behind the res... not realizing I could just do what you did.

I'm not using an Optimus, I have a EKWB.

My bad, youre right of course.  It even says vector right there.

Also, if you want to get the EK block, it should be about $100-200 less than the Optimus block, and you also won't have to wait until Fridays before you can get lucky and order it. The EK block is available to order today:

And, there is another thread with more information on the EK block at the following link:

So while browsing threads in the forum I came across a thread about the EK Acetal nickel block.  It seems the gen 1 block had some issues and they added some additional card mounting support in gen 2 to remedy it.  That would explain all the issues I was having with the block now, though to late to use it.
