Hello, I have an RTX 3090 FTW 3 and my temps are running hotter than what others are reporting. My idle is 49 C and when running games, it goes up to 81 C. Any tips? I have my computer on carpet with the Power Supply Fan going down. I have an AIO 240 mm at the front with two fans at the top and one in the back. 

Have you set up a custom fan profile?  or have you tried flicking the switch to OC.  Those temps seem very hot, for comparison my idle temps range from 22 C to 27 C, and when gaming my temps avg around 55 C.  I do have a large case and AIO for my CPU.

I don't have a custom fan profile. I just turn all of them up to 100%. Basically my PC is in the closet so I don't care about the noise. 
Also, I have the card at Memory +900 and GPU + 100 with Power at 119%. 
 
I've never gotten my idle down to 22 C or 27 C even when it's not overclocked. 
 
I've taken the side panel off which is made of glass and removed the front panel but no difference. 
I'm posting a link below of my case.

Being in the closet without airflow will heat up over time so I guess that could be part of the reason? I live in New Zealand, we are going into summer but the last couple of weeks have been unusually cool.  Yesterday, the outside temp was around 16 C outside, I had my windows open and gamed for 2 hours and on exit I checked the temps and the avg was 55C.  I browsed the web for a while and temps were sitting between 22 - 26 C.  The only other thing I can think of is that there is not good enough contact between the GPU and the heatsink, I would log a ticket with EVGA.  You may need to get a replacement card?
Your case is much smaller than mine, I have the 900D which is a super tower case.  I have 3 intake fans, a rear exhaust fan and 4 top fans 3 of which are attached to the radiator.  
Also my card is only running factory Overclock of 1800 Mhz, I feel that going past that just generates too much extra heat for too little gain.

For me the fans werent even on at idle, which bugged me and i regularily achieved 70-80c with the stock fan profile

Few problems with your setup.
 
1. Your case does not seem to have a lot of vents to intake / exhaust air.
2. It's placed in your closet which most likely has limited air flow due to it being an enclosed space.
3. You have the card running at max power with a+100 on the core clock. It's going to get really hot.
 
I guess you can try undervolting your card while trying to maintain performance if you mainly this card for gaming. That should help reduce a couple degrees. Best of luck.

Also while I'm waiting to hear back from EVGA and receiving the new case, I will try:

1. Changing the AIO Radiator position from front to the top
2. Remove the computer from the closet and run it in my room

make sure your airflow is good

I just got mine yesterday. I’ve been benchmarking in Control since the Northlight Engine is intensive and with RTX and DLSS all parts of the gpu are being pushed very hard. Power consumption and temps are considerably worse than every other game I’ve tried due to the above combination. Car slammed into the 450W limit with very small setting bumps and temps hit 80C. Ubisoft titles on the other hand do not stress certain parts of the gpu despite being hard to run and draw less power than most other game engines. 73C and 370W draw was typical. Ambient in both tests was 75F.

My case is a Luxe 2 and the card is mounted vertically with the add-in mount replacing the horizontal slots entirely, so the card is nowhere near the glass and still has 2 inches from the motherboard. Plenty of Be Quiet! fans cranked up on it as well. The only remaining option was to abandon the core slider and tune the boost/voltage curve manually. I left the memory at +250 (20Ghz effective) and maxed out the power and temps sliders. I set a maximum boost of 2040MHz at .975V. Normally this tries to pull almost 1.1V. Power consumption dropped a solid 30-40W across the board and clocks held at least 2010Mhz in rasterized titles versus just 1830MHz out of the box. Control could hold 1980Mhz, but power draw does still spike to 470W requiring a fan speed of 80% to keep temps below 80C.

These are very hot and hungry cards, folks. Like an old AMD Vega you benefit most from lowering the goosed stock voltage as much as you can for the boost you want.

hot air tends to rise so your airflow needs to make a way

Ambient temp and case airflow is everything.
When I game I set my fans to static 100% , Power and temp target to max, with a 143 Overclock on GPU and 500 on Vram, I rarely break 60c whilst gaming. Highest I have seen is around 62-63c. Max on voltage slider also (regular bios).

I do have a big case with good airflow, I'm sure there is something simple I have missed.

It isn't so much how good airflow but where is that airflow.  If you are not doing something to keep the warm exhaust air away from the card's cooling fans, then that air is heating things up..

I have 3 140mm fans bringing cool air from the front and 120mm exhaust at rear and 2 140mm fans exhausting through the top as well. My previous GPU would sit all day at 62.

Update on this:

1. My new setup is
   • Moved the radiator to the top fans below the radiator with a Push Configuration running at 100%
   • Front now has 3 fans that I had laying around so they're not the best but running at 100%
   • One rear fan at 100%
   • Still no glass on the side and the GPU fan is at 100% with no overclock
   • Computer is no longer in my closet, it's in my room with room temps being 77 F or 25 C. 
2. My GPU Temps are now averaging 60 - 64 C so that is a lot better. Still not as good as I was hoping for like the people above that are averaging 50 C during gaming. 
3. Maybe I need to wait on the new case and fans I ordered to see if there will be more improvement

You’re setting your expectations too high. These cards can pull 130W more than the 2080Ti FTW3 with only a slightly thicker cooler. It’s going to run warm.

Haha that's exactly what I'm thinking too about the 22 Degrees lol

The 30xx series cards are power hungry and are gunna run warm, even with good cooling. Your Temps sound fine, I wouldn't worry.

I ran 100/900 OC and would idle 32C and peak around 65C.  Thermals really depend on how your case is set up.  As everyone else said though, you're in a good range.
