Not that I support scalping, but if you decide you don't want to keep the card, you will make profit on EBay, guaranteed, all of these 30-series GPUs are selling for well over retail, even if listed as slightly used - you can just list it for retail then see where it gets bid up to.  Even after the 10% fees, you'll make profit.

 
I took a look at sold 3090 XC3 Hybrids and they are going for right around $2000 (lowest I saw was $1995 for a sealed one).  So after 10% and say $20 shipped insured, that comes to $1,775, which is pretty much exactly what I paid for mine with taxes and shipping.  The market for 3090's is not the same as for 3080's due to the value proposition for just a 10% performance increase.
 
I also noticed the memory gets insanely hot when doing memory intensive work.  My infrared registered 180F on the backplate!  The AIO only does the GPU, not the memory.  The blower fan does help with the front mounted memory modules, but does very little for the ones mounted on the back side.  Yes, there are thermal pads on the memory chips on the back to the backplate so a fan blowing across the backplate does bring the temp of the backplate down to around 165F, which is still way hot.
 
I'm curious if the 3090 Copper is any better at cooling the memory chips on the backside.  From the pictures I have seen, it doesn't look like it.

I read some reviews. I'm sad to hear that these have a loud pump in them. Maybe the 4080 Hybrid will be for me.

I mean saying "they have a loud pump" because 2-3 people said theirs does is a bit of a stretch.
 
I think at least one of those "loud pump" people so far has a faulty pump in their card for sure, based on just listening to his recording of it - he's working with eVGA to get the card RMAed (it literally sounds like his pump is grinding so that's definitely not normal pump sounds).
 
I'll be receiving mine Wednesday & I'll be sure to report back on pump sound or the lack thereof... though being able to hear it is always a "maybe" over the general system hum because uh... 16 fans.
 

 
Well, technically speaking it's 20... because there's 3 on the GPU & 1 on the PSU... details.

For the 3090 memory they have half of it on the backside of the PCB I believe, and this is not directly cooled by the active cooler.
 

I have the same question (3090 FTW3 Ultra) do I need to switch to the hybrid bios? Mine arrives Wednesday. I'm still unclear. I asked multiple time during evga weekly and no answer. Others asked as well.

Has anyone posted any before and after numbers with the Hybrid kit? Really curious how much AIO kit improves over air cooling.

The pump on my XC3 is quiet.  The rad on mine is mounted above the pump/card.

The pump on my 3090 XC3 is also really quiet. I also have my rad mounted above my card.

Quick question, what clock speeds are you or anyone else getting with the 3090 XC3 Hybrid? So far I have hit a max of 2055 while playing Cyberpunk with just normal boost clock. Normally the boost clock speed stays at a steady 1985 while playing games.

Getting mine this Friday. Will it be OK to mount the rad in the front of my case? I have an ITX build so my options are limited. If I mount to the front of my case, what orientation should I have the radiator. I.e. should the tubing entering the radiator be positioned towards the top of the case or the bottom of the case?
 
Also. I have a 3600x and now the xc3 hybrid. Will my evga 650 gq PSU from 4 years ago still hold up? I know people refer to tier lists for PSUs but I feel like this particular PSU is not talked about all that much. Hoping someone might have some insight on the EVGA forums :)
 
Thanks in advance.

Tubes down is always ideal, tubes up is okay as long as top is higher than pump but there is air in these AIO for sure.

The first few seconds you plug and power these on you can hear air cycle through the AIO. So having tubes up you'll have air present, it can't travel to the pump easily but cavitation can happen a little bit.

Tubes down is always best or Radiator top which does the same thing, tubes only exposed to water.

Thanks for the info! So looks like I'll have my rad mounted vertically at the front of the case with the tubes entering from the bottom. One more question regarding airflow. Is it reasonable to only have 3 fans in an ITX case? I.e. having the two fans on the radiator as intake and one case fan as outflow. Or should I add an additional fan for outflow? And to have the radiator fans set up for intake in the front of the case, would the order be:
<- Radiator <- Fans <- Front of case
Or is it more the orientation of the fan rather than the order of radiator vs fan that matters? Sorry, I'm new to AIOs so I'm trying to make sure I set this up right :)

If you only have one exhaust fan i would reverse everything, heat will build up inside your system. At least reversing everything heat is exhausted.

I would add the second fan for sure.

Edit: the best configuration is push-pull > Push > Pull

I would put the fans in a push configuration where they push the air through the radiator.

If possible, mount it with the tubes down at the bottom (which should be possible in an ITX easily).
 
If you're getting a 3080, that 650W is not ideal, if you're getting a 3090, upgrade PSU, don't risk your system on a lower wattage power supply.  I would recommend getting at least a quality 850W in either case to be on the safe side!
 
Also, you should seriously consider mounting the GPU radiator as EXHAUST - these things put out over twice the wattage-based heat as a CPU, you'll be pumping very warm air in to your case if you have it setup as intake, which is not ideal.
Regardless of orientation, I second the recommendation of (if you can only fit one set of fans on the radiator) doing PUSH (having the fans blowing air through the radiator) as opposed to having them in pull (sucking air out of the radiator).

What kind of temps are people getting with their xc3 ultra hybrid? In cyberpunk I get to 60C after a few hours of playing. Had to remove my front cover to my 280x to get it back to 55C.

Sounds like your system has some serious airflow issues, people with "good airflow" on the forums seem to be getting temps in the 50s for the most part post hybrid install or with their Hybrid cards.
 
I'll report my temps once I get my card installed, should be here today according to UPS' latest update.

Thanks for all the advice. I'm going to get an extra fan so I have two intake case fans and then set the fans on the radiator to push out the case as you all recommended. Are the fans that come bundled any good? I'm thinking of getting some static pressure fans instead. And to save money I was hoping to just reuse the bundled fans as case fans. Is that reasonable?

I noticed that scalpers (and others) who are selling them are just looking to get their money back. I have a feeling that it's mostly scalpers. They probably thought they would get 3k for them and now it's down to 2k minus fees. I just saw a 3080XC go for $1150 on ebay. It was $1125 and someone bid it up right at the end. At least it didn't start jumping by the hundreds right at the end when the serious bidders tend to show up, but $1150 is still wrong. This "launch" is so messed up. The timing makes it even worse because you know a bunch of db kids are screaming at their parents right now to get them one of these cards for Xmas. Plenty of others too who can't wait, or have more money than sense.
 
It's just one of many reasons why I am fine with waiting for a HC. I would rather that the impatient ones get theirs first. It's all good because it means fewer people to compete with when the HC's come out. In the mean time, I hope that EVGA drops a mountain of air cooled cards and gets through those mile long queues. Cards from other manufacturers will continue to drop at a similar rate and demand will start to drop over the next 1-2 months. It's just as well that the HC's are delayed. It's important that EVGA gets them working properly, and it also draws attention away from them because a lot of people don't want to wait, or are not interested to begin with. Gosh, why would you wait if you could pay $1150 + fees for a 3080XC right now.

  The AIO only does the GPU, not the memory.  The blower fan does help with the front mounted memory modules, but does very little for the ones mounted on the back side.  Yes, there are thermal pads on the memory chips on the back to the backplate so a fan blowing across the backplate does bring the temp of the backplate down to around 165F, which is still way hot.

The AIO cools the GPU and the memory. EVGA even has a patent on what they did. "Patented copper memory plate" and it shows a image of the memory plate on their site.
 
Now lets cover how this works. When I was installing my kit, I saw thermal paste on my memory plate. I was about to wipe it off because I thought it was on there by accident. 
 

 
Then I realized what they were doing, the thermal past makes contact directly onto the AIO itself. Then I told myself "DUH!" Good thing I didn't wipe it off. 
 

 
So now EVGA is making use of the edges of their AIO to extract heat away from their memory. And I took measurements of this.

For reference, here's Gamers Nexus measuring the memory temperatures 
 

So the plate being tied to the AIO actually works :)
 
Now I know the 3090 has memory on both sides, but this should still help. The card will still extract heat away from both memory modules due to contact and thermal conduction, just not as efficient. The rear memory modules are still attached to the backplate with a copper base. 

 

The pump in the 3090 FTW Hybrid isn't loud. Even at full load the pump/radiator fans are still pretty quiet. Mine completely died four days after it arrived, but otherwise it performed well.

Yeah, the 280x might not have been the best idea for having two rads lol.  I have no choice but to use a pull instead of a push fan config.
