Remember the 3080 Ti is cut down 3090. Look at 3090 Temps which tend to fall around 93 degrees.

i just installed my 3080 TI and i ran heaven benchmarks at 1440p max settings it was hitting 79-80C is that bad?

Good airflow and moderate undervolt should keep any of these 3080-3090 under 70

how much voltage for a 1920 clock you think?

My 3080 was stable at 1950 @ .900
I would start at .925

thank you! whats your temps & model of card?

It's running pretty warm because it's a 3090 minus 2 SMs. It will be hottest when you use all acceleration units and any significant amount of memory. So ray tracing (RT), DLSS (tensor), lots of vertex geometry / physics simulation a la PhysX & HairWorks (CUDA), and high quality textures / high pixel count (VRAM). Turn off any RTX features, and disable AA if you're playing games at high resolution like 1440p & above; alternatively, reduce resolution to 1080p and use AA to make up for less fidelity.
 
Make sure to cap your frame rate so it's not running full throttle when it doesn't have to. Might want to set power profile in Nvidia control panel to adaptive or optimal if you don't need the almost-3090 performance and would rather keep it in a lower, more efficient state most of the time, which is absolutely what I'll be doing.
 
That will hopefully keep your temps in a better range. You should get EVGA's Precision / XOC software to get temps from the many iCX sensors AND crank down the power target, and maybe the core & memory frequencies depending on how important better thermal performance is.
 
Cannot stress enough: This is essentially a 3090. The die was a rejected 3090, and it likely means its of lesser silicon quality in general (not a "golden sample"). That means it will need more power to reach parity with the clocks & stability of a typical 3090 GPU. More energy means more heat. Period. Luckily, there aren't boiling hot memory chips on the back of the 3080 Ti, so it should still be a bit cooler. Other than that, treat it as a 3090* and scale it the hell back if you are fine with 1080/2080 Ti performance but with the potential flip a few settings to rock a top tier flagship GPU that admittedly runs pretty warm.
 
* And I think no SLI, and it's LHR... Still mostly a 3090 GPU for mainstream gaming.

Those temps are fine, but turn on the OC BIOS to reduce temps. Also, your case and airflow could suck. I just played Apex Legends maxed settings 1440P 144hz, then ran 3D Mark and never broke 71 as the max temp. This card is amazing.

its a corsair air 540 two 140s in the front and rad at the top, 280mm

Nice case. I'd remove the front dust filter, see page 5:
 
https://www.corsair.com/corsairmedia/sys_master/productcontent/CARBIDE_AIR540_InstallGuide.pdf
 
Tie the front fan speeds to system temp in bios so they come on stronger when the GPU heats up the system.  Or use "Fan Control" freeware to tie them to GPU core temp, this can be a bit easier to adjust them by noise level since you can tweak while the system is under load.  Then set a fan curve in X1 so it gets more aggressive with the card fans.
 
Monitor Memory Junction temps using HWiNFO, if your core is getting hot the VRAM is usually 25C or more higher which is pretty questionable.
 

Quick update, my front filter was filled with dog hair... oops. after cleaning it out heres my temps after a 15min heaven run. I will say this card is very loud, using the aggressive fan curve mind you

HUMMMMM.  Granted we don't have that much experience with the new cards, but it's kinda strange to see the GPU core, hotspot and vram temps all in the same ~10C range.  Might have slightly insufficient paste or some cooler warp.
 
Are your case fans cranked up?  I'm assuming you left the filter in place, ew.

case fans are running at 500 rpm LOL

LOL WUT?  That's not enough man, case fans make a huge difference in feeding the card's intake fans fresh air and pushing hot air out of the case.  At a minimum they should be running fast enough to be as loud as the card's fans.

I'm at .890 volts, here's a timespy result!

The problem with that is you’re leaving a lot of perf on the table.

The thing is under warranty and not likely to fail anytime soon. Crank it up, turn up the fans and enjoy the perf you paid for. You should be up around 21K with a lil overclock.

Not bad, just higher than average. No issue whatsoever, but it isn't the card that's the problem it's probably your case and airflow. These cards don't dump heat out of the back of the case like your last card probably did. Welcome to 2021. Time to upgrade your cooling and airflow.

I also have pretty high temps. I set my two front intake Scythe Kaze Flex 1800RPM fans to full speed (in case you never heard of these fans they push crazy air at max RPM and are well reviewed) and I sety a constant 80% fan speed on my FTW3 80 Ti which is as high as I would ever want it in a normal scenario. My case is a fractal Meshify 2 which is generally considered a good air flow case especially if you upgrade the fans, which I did. I also have two exhaust fans in the back which are just the stock 1000rpm fractal fans but that should be perfectly fine for exhaust purposes.
 
Genuinely curious what I'm apparently doing wrong with air flow in my case. Techpowerup also had this GPU hitting around 80c as stock settings so it doesn't seem to just be a me problem. Though too be fair before settings my case fans to a constant 100% and the GPU 80% it actually hit 86c. Which is pretty damn hot even if I did have very bad airflow, (I really don't). It really feels like a problem on EVGA's end, while technically they're charging less than most other AIB's for this card right now, under normal circumstances this would be priced similarly to a Strixx. So It's a bit disappointing how it performs thermally.
 
At this point I'm going to be forced to undervolt the card and run the fans higher than I would like due to noise concerns.
