Switch that exhaust fan to the left of the CPU to intake.
 
Other than that, a new (old?) case with mesh sides and slots for intake fans. I know the new fad is glass sides, but it's not idea for non-blower cards.

This might not make sense on paper, but try setting your radiator fans to intake. I have found that gets me the best temps for both cpu and gpu in my case setup. I think it allows more of the fresh air front the front to be used by the GPU rather than being removed from the case. It will also give you better air pressure inside the case since you will have more air being taken in than exhausted. Cant hurt to try.

I don’t get hotter then 72 73c on standard bios. 1700 rpm Something is def wrong

P600s

I am facing the similar situation, here is what I have done so far to keep the card in relatively low temp.
 

1. Tune the fan speed with acceptable noise to optimize the air flow, it may help 2-3C
2. change the case, I have changed my case from InWin 103 to Lian Li Lancool2 Mesh, without tuning the fan speed for air flow optimization, it already drop 4-6C. I will try to optimize it in this weekend, may report the result after that
3. Undervolt your card. The main cause of the heat is power, with avg. 370-400w in default, ftw3 definitely produce more heat than other cards. Many complain that EVGA have set the power too high in same frequency when compare to other cards, but I believe EVGA assuming most FTW3 users will play overclocking so a high power can stabilize the OC process. 
   If you are playing games in default setting, you may try to undervolt it, I can keep 1920Mhz with 0.850mv which use 300-320w, you may lost 1-2 fps but the temp will drop ~10C.

This seems to be a common question but I am wondering what I should do about my setup. Photo attached. My temperatures are 80C while gaming (Metro Exodus) fans are at 60%. Anything more than that I find to be pretty loud. When I remove the side panels temperatures go to 76C.
 
80C though not dangerous for the hardware, is higher than I would like and higher than the reviews I read before purchasing. My case has 2 140mm intake fans on the front going at 1000 RPM, one 120mm exhaust fan at the back also at 1000 RPM, and then two 120mm exhaust fans at the top going at 1200 RPMs. My goal was to keep a rig that was more on the quiet side which is tough for this card.
 
Any advice on my setup to decrease these temperatures? I was hoping to be in the 70s on the card with the side panel on. The card is in OC mode without any additional OC. Other than increasing fan speeds I am not sure what else to do. It's a smaller case (Meshify C mid) but still a mid tower. I know these cards pull a lot of power and therefore dump a lot of heat but I was just curious if anyone had any thoughts. Thanks.

A few things I've noticed here.  For one, being a smaller case versus a large case, these GPUs need cooler ambient air flow.  You can't have both quiet and cooler on air, especially in smaller case.  You're going to have to sacrifice in order to dial things in when it comes to medium or smaller cases when using high end GPUs.
 
Check and see if you have your filter installed up top.  If so, you need to switch the fans to intake from the top (cooler air in) as you're literally circulating exhaust against your top filter.  
 
Another possible issue with the top is, having the top as exhaust will direct your front air flow leaving your GPU starved for some air.  So basically the top is taking a good chunk or at least a half of the front intake air away from the GPU and than circulating it off the top filter, presuming there's one up there.  Either way, have your top flipped to intake and use the unfiltered rear as exhaust. 

Also, what screen are you using?  1080p/1440p/4K, 60/120/140/240 hz?  Cap your FPS incase you're going past your screen's limitations since all your'e doing is pushing your GPU which ends up using more energy and creates more heat increasing your overal temps.
 
Once all of that is done, I would play with your cooling fans and see where's its more tolerable if you were to incease them say in 100 RPM increments while putting 100% load on the GPU to see where it settles and keep tuning it to your liking.
 
Worst case, I'd recommend grabbing a EVGA 3080 FTW3 Hybrid Kit once they're released in the coming weeks or month or so.  Install that to the front as intake with your top as intake as you should some  improvements overall.
 
Hope this helps.

In that case, most of the air your GPU is going to see will come from the lower front intake fan, and looking at the photo you posted, the hub of the fan looks to be right at the gpu, so at best the air from the lower 1/2 of that fan is making it down to the GPU.  Your case is likely negative pressure given the 3 exhaust fans, and that's all coming from above the GPU, it's possible that little/none of the air from that front fan makes it down to the GPU as a result.   I'm not sure if the 140 fan mounts in the case are rails or just static holes, but if you could slide that lower front intake fan down it should help out a lot.  Should also consider putting that rear exhaust fan at it's lowest RPM possible and turning the front up a bit.  If the points are fixed, you'd likely be better off with the 3 120mm fan config in the front to get more of the airflow down to the GPU.   Your ambient air temp also has to be considered here and I don't think I've seen it mentioned or asked by anybody.   A lot of the reviews I see use A/C to maintain ambient temps around 21c/70f, so if your room temp is higher, you should expect a higher temp than what they state. 

Undervolting is definitely a solid option if temps are too high. I dropped temps by about 5c with a fan curve so in reality it’s more than 5c since fans are spinning at lower rpms when at lower temps. I managed max boost clock of 1980 and average clocks are 1960-1965 at .95v with temps staying in mid-high 60s. I eventually plan on upgrading my 750w psu and buying a case where I can top mount my aio. My current front mounted aio increases gpu temps, so when I get that new case/psu I’ll max out voltage and wattage while unleashing the cards max power and voltage, but for now undervolting works great.

Hello Today I experienced same thing.
 
Playing Metro Exodus RT 4k gave me 74-75C with aggresive fan curve. My case is Enthoo 719 with 2 bottom intake 2 front AIO Intake and 3x 140 AER's.
 
Hey I'm playing Metro Exodus too. in 4k, I have a question are you guys experiencing any kind of artifacts I mean is really micro but it just bugs the heck out of me. like little flicker of lights, this is the only game that is doing it, I too have EPIC Launcher maybe that is why I'm getting those flicker of lights, my temps hover around 62-65 so I'm pretty sure I'm good at that end. I really hope is the game and not my card because that would suck . I already playing Wolfenstein NC/destiny 2/ and DOOM all in 4k max setting and no flickers or issue, oh and also Battlefield V. So maybe is just Metro Exodus

This is a card where having a pretty sealed box of a case will utterly destroy you. There’s no “blower” function to this card unlike the FE and you need lots of cool intake and good exhaust.

I have the FTW3 Ultra and have played with airflow and fan settings to achieve cool temps.  My card idles at 27c to 28c with three monitors running (One 4k, two Ultrawides at 2560x1080).  At full load my temps settle at 70c to 74c max even when gaming in 4k at max graphic settings.
I have 6 Thermalake 120mm and 140mm fans, and one fan that came with my case (no name on it, but it is quiet... Lian Li Lancool 2 case).  Here is how I achieved the temps.  PC is a i5-10600k with Arctic e34 Duo air cooler.
 
1.  Open case, go into your bios.  Leave CPU fan settings alone, we are only doing case fans.
2.  Drop all fans to 0% across the board so all fans stop.
3.  Raise one fan above 0%... look to see which fan spins up.  Identify which fan is set to each selection.
4.  Set all case fans except the front to 40% at 0c, 50% at 40c, 60% at 60c, and 100% at 85c)
5.  Set front fans slightly higher (I place the largest, most quiet fans in the front pulling in air).  Set to 60% at 0c, 70% at 40c, 80% at 70c, 100% at 90c)
6.  Observe fan RPMs, You do not want RPMs to be above 1500 as the fans will be too loud.  Mine sit at 800 to 1000rpm at idle.
 
I had to make sure the one off-brand fan had it's own settings to be slightly slower than the Thermalakes as it was not as quiet. I set it to 800rpm at idle.
 
Fan setup....

 

This is why I upgraded some of my 120mm to 140mm.  Any little bit helps.  I plan on replacing the 120mm on top with a 140mm, and replacing the no name fan on bottom with the 120mm from the top.

As a follow-up to my previous post:
https://www.overclock3d.net/reviews/gpu_displays/asus_rtx_3080_oc_strix_review/21
Provides an interesting set of data.
It is entirely possible that your game is running the card very hard, essentially doing a stress test.  If this is the reality, then your temperatures are in fact completely normal.

One way you could test "is airflow the problem" going on is quite simple:  Turn ALL of the fans in to intake.  That will insure your system is getting beau-coup cool air in to it, and the "hot air" will go out... where-ever it can.  Your case has plenty of "mesh" areas the hot air can go out, so this setup "should" work & show you, sort of, what your "best case" scenario is with your current fan/case setup.
Then, one by one, adjust the fans you prefer to be exhaust, back to exhaust, until the temps start increasing a lot.  Once you reach that point, put the last one you changed back to intake, and go for it.
Alternatively, you can do the opposite of this as well, turn all of your fans in to exhaust, which will cause the case to suck air IN from anywhere it can get it from.  
You can also try both of those methods & see which one works best.  It's different for every case, and different depending on your hardware setup as well, what setup works best, and experimenting can usually lead to better airflow & better temps.
Never trust a case's default layout, or the layout they show in the pictures... as reviewers like Gamers Nexus regularly show, default configurations on most cases are utter garbage, and what they show in pictures is often a bad idea in reality, for cooling/airflow.

I know these cards pull a lot of power and therefore dump a lot of heat but I was just curious if anyone had any thoughts. Thanks.

For what it is worth I just completed some calculations for my own PC and thought I would share the results.  It may provide some insight.   Doh I can't paste a table in this forum.
 
So: 
I use Corsair 120 SP pwm fans I assume these are close to yours:

• These fans move ~0.03 CFM per RPM or 30 CFM @ 1000 RPM, 36 CFM @ 1200 RPM

I also use Corsair 140 HD fans:

• These fans move ~0.055 CFM per RPM or 55 CFM @ 1000 RPM  

Basically you need to match the total inlet CFM with the exhaust CFM, if they are mismatched you create a pressure differential which results in a loss of efficiency.  ( Simplified explanation: Power = (Pressure change) * Volume/time ) so if the pressure change is 0 there in no power loss) With a mesh case you just leak air with some resistance so the impact is lower.
 
Based on your description you have : 

• Approximately: 110 cfm intake
• and (30+2X36)or 102 CFM out  This indicates that your airflow is pretty balanced.

Next we need to estimate the what air flow the FTW3 needs @60% fan speed: ?

• This unfortunately is a best guess (I cannot find specifications), but somewhere between 35 to 45 cfm per fan or around 115 to 135 cfm total. Edit: some new data from a techpowerup review indicates the requirement may be more towards the high end of this estimate.

Analysis: It looks like your FTW3 needs more air than is flowing through your case, this means heat will build up in the case until equilibrium is reached.  Basically confirming what you are seeing with the temperature drop to 76 when you remove the side panel.
 
Theoretically if you

• add one more 120mm intake fan and one more 120mm exhaust fan you increase flow by ~ 30 cfm (you could try to just add an additional 120 mm intake, the mesh case may take the heat away through leakage.) or
• Convert the 120 mm fan on the back to an intake and convert the 2 -120mm top exhaust to 140's (This would add ~30 CFM total airflow,  new top 140 mm fans would need to be around 1250 rpm ) 

The air flow through the case would then match the "estimated" needs of the FTW3.  I would expect the temps to drop closer to the 76 degrees you measure with the side panel off. 
 
N.B. I believe an earlier poster suggested changing the 120 exhaust to in intake, the math confirms his advice.
