At the end of the day, even if the temps are higher than they "should be", as long as I'm not getting thermally throttled, I guess can live with them.  Should I be concerned about card life expectancy at all, where I'll be gaming a few days a week for a few hours a day, with temps in the mid-to-high 70's?
 
*UPDATE* - I'm getting thermally throttled, going from 1,995 Mhz Boost Clock to 1,950Mhz, while GPU1/2 Temps are at 72c and Memory 2/3 Temps are at 75c.  Everything is at stock values (No OC on Memory, Core Clock, Voltage or Power / GPU Temp Targets).  Well, that sucks.
 
Any last thoughts or suggestions before I RMA the card?
 
Thanks everyone.

Reading through a couple of thoughts.
 
It isn't GPU1/2 but GPU1/Mem2
 
Are you blowing air in or out of your case with the radiator?
 
do you have roughly the same amount of case fans blowing in the opposite direction?  Not that you are creating a vacuum or high pressure that the fans are fighting with.
 
If you are blowing air from in to out, do you know what the internal temps of your case are?  Not that you are just blowing hot air from the CPU/GPU across the radiator?
 
If it isn't any of those, it is likely either a pump issue or thermal paste application issue.

Hey Baratak - I'm blowing air out of the case with the Rad.  The ambient room temps are 20c and the in-case temp is 21c.  It's pretty darn sure it's not an air-flow / hot air situation.  As I mentioned earlier, I had the 1080ti FTW3 Hybrid card before  getting it's 2080ti variant, and it never got hotter than 55c, under extreme load (Superposition / Heaven / 3dMark as well as BF5, Anthem and Kingdom Come Deliverance).

At that point I would either RMA, or with EVGA's Tech support blessing, replace the thermal paste. 

Baratak - yeah, I'm going to RMA it.  I honestly don't want to muck around with taking the shroud off and dealing with Thermal Paste - that's why I bought the Hybrid card to begin with.  I appreciate yours and everyone else's suggestions and help.

The 2080 Ti FTW 3 Ultra cards can pull a lot of power...much more than the 1080 Ti did.  So it does make sense that you are seeing higher temperatures.
 
When you are looking at GPU and CPU temperatures, you need to reference against ambient...otherwise, they don't mean anything.
 
For an experiment, I would turn your AIO radiator input fans up to 100% and re-run your base line (noting the ambient temp).  If the GPU AIO radiator is getting starved for air, the increased flow should help.
 
I never really liked putting the GPU in the back slot, with exhaust fans out of the top.  You are limiting the air flow to the GPU radiator...simply because the first exhaust fan is pulling air out of the case...the second exhaust fan is pulling air out of the case (having to fight the first exhaust fan)...and the GPU radiator fan has to fight both of those to pull air through the radiator and out of the case.
 
For my setup, I have both the CPU and GPU AIOs in the front of the case as intake (they each have a push/pull fan setup).  I have two fans on the bottom of the case as intake.  The fans on the top and back of the case are exhaust.  This way, the radiators are seeing the coolest temperature air (as the best they can cool to is the temperature of the intake air.)
 
With this setup, I get temperatures for my 2080 Ti FTW 3 Ultra hybrid as follows (with a 26 C ambient):
 
250 W Power Draw: ~45 C
275 W Power Draw: ~47 C
300 W Power Draw: ~49 C
325 W Power Draw: ~51 C
350 W Power Draw: ~53 C
 
This is consistent across two different machines (I have two PCs, each has the same 2080 Ti card in it, with the radiator as input and push/pull fan setup).

When you shared that picture you had your hoses rather twisted, you could be constricting water flow somewhat with them like that.  I know I had to spin my radiator around once to get the hoses in a much better alignment.  See pic.

KSGNOW2010 - So, if I crank both fans (Rad + Card) up to 100%, GPU1/2 and Mem2/3 are in the 54c to 59c range, after 4 Heaven Benchmark runs.  Mem1 is at 40c.  It's better, but still high, IMO.  I RMA'd the card, so I'll try again with a new card.

So from what you've said in earlier posts, you have 6 intake fans(top and cpu rad fans) and 1 exhaust(gpu rad)..  Not enough exhaust IMO.  I have a 570x corsair case, with a h115i mounted on top(2 fans exhausting out of case), my hybrid ftw3 mounted same spot as you as exhaust, 3 intake fans on the front of the case.  I also had a 1080ti sc2 hybrid.  The sc2 never went past 45 Celsius. 
Had a 2080ti XC Ultra temporarily, temps were 60-70.  Anthem caused the card to get to 85ish with fans at 100%, decided to get the hybrid again as I was uncomfortable with those temps.
Switched to the ftw3 today.  Idles at 30ish, Havent had it go past 60 yet loaded.  I think these cards do run a bit hotter then the previous version.  
 
 Not sure if it's a possibility but if you can fit your CPU rad to exhaust through the top, and have 2-3 intakes bringing in cool air from the front.

I have not touched my fan curves , they are default and generally the radiator fan (FAN 2) runs in the 90-92% range with stock settings when the card is under full load.  Its not loud at all only about 1850 RPM, GPU1 never gets more than 55 deg, GPU2 around 63 deg, mem 1 in the 40's memory 2-3 stays in the mid to high 60's.  The air cooling fan over the power (FAN 1) units only spins around 45% 1500-1600 RPM and of the 5 power the highest is 55 peak.  Not sure if the fan curve in your bios is different than mine though since it's an Ultra maybe? I'm running it on the standard bios switch and the bios version is  90.02.17.00.D1
 
I can't see where lowering fan 1 would cause your CPU to go up much as its just cooling a heat sink over the power area.  Technically though you have the non Ultra edition so you would think it would run slightly cooler than mine at stock.

Mav - I really do think I’ve got a bum card / rad / pump. My new one comes in tomorrow, so I’ll be sure to post the temps of the new hybrid. Thanks man.

I'm pretty sure these are assembled by hand so the card itself is probably fine but the cooling block may not have been well seated or could have air bubbles in the cooling paste or something.  Or could be the cooler itself.   I'll cross my fingers for you that you get a better lottery ticket the second time around :)

Mav - new card, same results. I installed a second fan to the rad (Push / Pull) by snagging one of my top exhaust fans and temps dropped a good 7-8 degrees C, with the case doors off in a room (my work office) that’s 25c. Getting two more SP120’s to replace the stock EVGA fan and for the Push fan for the rad.

I’ll bundle it all up tonight, bring it home, and will post the temps. Damn that I didn’t see this with my 1080ti Hybrid.

Overall my RTZ Cards Run 12°C to 18°C Hotter than do my GTX Cards.
On Air Or On Water.

I run the two fans off a motherboard header...through a splitter.

I'm assuming the 4 pin header the current radiator fan is on could handle 2 of these Corsair ML120 Pro fans with a Y-Splitter don't you think?  Seems like it would be best to run them off the GPU so you can have them sync to the GPU temps.

? Why risk damaging the card doing that? $1500 down the tubes, warranty lost. Run the 2 fans off the motherboard or just a fan controller better at 100% all the time or possibly the included adapter (with fan) that has a resistor to run the fan at like 50 or 75% not sure on that.

Push/Pull FTW, Mav.  I'm home, in a room with much better ambient temps (20c) and during my 4th Heaven Benchmark run (it's running while I type this), most all temps are between 53c and 57c.  It's not anywhere near as hot as it was without the push/pull config.  I will declare success with those temps.  Why would EVGA ship a ****ty 120mm fan and a ****ty 120mm Rad with a beast that pumps out more heat than my wife does when she's angry at me?
 

 
Well in all fairness the stock one did keep it cooler than the air cooled model for the most part right? 1 fan does better on mine but my case has pretty great airflow.  Only reason I want to try push/pull with mine is I may want to OC it at some point.  Maybe I will just put one of the Corsair fans on and see if it performs better than the EVGA one. 
 

Ive only noticed a 1-2c difference with dual fans on the 1080ti ftw hybrid I use in my sons rig.. no point for me. Of course though I run it at 100% and maybe it makes a bigger difference with the hotter 2080ti.
