Undervolting.  Sigh.
 
Undervolting is dangerous and does not reliably reduce power or temps.  It can give inexperienced users a false sense of security while they overheat their GPU for hours on end.

Undervolting is reasonably safe and reliably reduces temps. There's absolutely no way undervolting would lead anyone to overheat their GPU if it wasn't overheating already.

Re-read my post.  It is dangerous because it gives a false sense of security.

I undervolted my card and fried it because I had a false sense of security.. said no one ever.

That's because the people who do it are idiots.
 
I bet you more than half the new world blown 3090's had an undervolt.

That is a hilariously ridiculous thing to say. Although, it might be true, if only because there's no reason not to undervolt your card, and anyone who's spending $1500+ on a GPU is more likely to undervolt than your average consumer. Correlation not causation and all that

I want maximum performance therefore I do not undervolt.  Never have and never will instead I would rather overclock and give the thing more juice These cards are built to be used this way.
 
Green freaks or people who have poor cooling/power undervolt.   It's like putting lower octane fuel in a sports/muscle car, I'll never understand this.

UPDATED OP. Problem solved. 

Looking better, but 80C at 280w is still very hot.  Need to work on your cooling config, get more air through your case.  Can run mine at ~425w and 68-70C.

Unfortunately this was a short period of joy. The error happened just again. Will contact EVGA.

But someone who can't keep their card cool at 400W, applies undervolt and sees "oh muh 20C cooler temps!" at a light load, turns down their fans and doesn't watch temps, can easily hit 400w again and overheat on a heavy load.  Like New World. 
 
I automatically assume people who undervolt don't know what they are doing, because they were not able to adequately cool their gpu.

When you make up completely fictional scenarios in your head and treat them as reality, I suppose you could come to that conclusion. Undervolting my 3080 reduced my already adequate temps a few degrees, and it runs games great. There's no harm to undervolting, no matter how many straw men are running around your imagination.

Cool story bro.  Please take your normal gaming settings, including fan speed, and run Furmark 2X MSAA for a half hour.  Then run New World.  Let me know how it goes.  Thanks!

Do you know why the Power Target changes all the time while on Default? Would still like to know why @86°C threshold the fancontrol stops Fan 1 and Fan 2 while Fan 3 is running @99%.
Would be fine if a EVGA Technician could make a statement one this issue. 

On default, power is supposed to be 100%.  X1 shows a power reading in the main page by the slider.  If you are hitting thermal limit, the card will restrict power to get it's temps under control.  
 
Sounds like you have something seriously wrong with your fan control (obviously), but I don't know how to fix it other than all the typical hardware and software troubleshooting steps.  See if you can eyeball the fan connectors, they are by the PCIe.

Furmark runs fine, temps are around 71C. And I have no interest in MMOs, especially not one made by Amazon.

Yeah I've seen practically nothing but benefits from undervolting. Only downside is that every now and then a new game will come out that will prove your undervolt to be unstable, so you may have to tweak and create a separate, less aggressive profile just for that game.

Also, I believe the person above who viewed undervolting as decreasing the performance and capability of a card to be wrong. Undervolting can basically equate to OVERclocking at certain lower voltages. This can lead to significant performance improvements, particularly for power limited cards.

Not sure why the undervolt hate?

same here, undervolting has been working great.  My gaming time is 99% for VR via my G2.  I do have a custom fan profile too, and I don't mind the fan noise 'cause I can't hear it when my HMD is on.  Rock steady, locked in performance.  temps are great. 
 
100% agree with you Fuzzy

As long as you're hitting the same clockspeeds, there's no reason not to undervolt at those speeds. And you're straw manning again. Recommending someone to undervolt is hardly a solution to anything, but it can certainly make temps/fan noise better.

Only people I know undervolting can't get a proper OC on their card and cool it enough to run it at max power.

It also make no sense to kneecap a $1500 GPU.

Not all undervolting decreases performance. If you are smacking off the power limit at 1.068v and getting power limited to 2000MHz, then if you undervolt properly then you may end up with 2050Mhz at 1.05v with the same power limit, so higher performance.
 
That aside though, I do agree, its never something I'd do voluntarily unless I was getting higher sustained clockspeed out of it. And while its certainly never a 'solution' to a heat problem, in some cases (heatwave, case fan failure, A/C failure etc) its a decent enough stopgap.

 If you can't get 2,100mhz on an GA102 while gaming, it is either too hot or not getting enough power, or you need to crank up the OC.
 
Locking voltage at 1.050V is not undervolting because the card would normally expect to operate around that voltage.  Anything 1V (.9V?) and over is not an "undervolt".  When I lock my core voltage to 1.1V and put my PC outside in the middle of the winter to run benchmarks, do I call it "overvolting"?  No, because that would be dumb.
 
What you describe is called "locking voltage", which can be useful in any number of scenarios. 
 
If you turn down power limit, is it undervolting?  No, it's turning down the power limit.
 
I have no problem with people locking their core clock and voltage to whatever they feel like, or reducing power limit.  I do have a problem with it being recommended as a solution to overheating.

Yeah I think that's fair enough. I put the hybrid kit on mine and temps plummeted. Funnily enough, my undervolt became completely unstable as soon as I put the hybrid kit on. Never really figured out why. I just don't bother now as the performance I get at stock is great for gaming anyway.

Your undervolt became unstable because of the lower temperatures which add increments of 15 Mhz to your clocks. You see the graph below? You get 15 MHz more for every section of temperature you manage to get your card in.

Why not cool the card better and undervolt? 

If your card is cooled properly to operate at sustained max power limit at under 70C, you can apply plenty of normal core overclock and Boost 4.0 will do the rest.  
 
If you want to see the ultimate result of cooling the card better AND locking voltage:

Which of course is Not A Good Idea.

I lol'd.  Yeah I had the same thought about voltage and current, and how it relates to heating.  If you hold clock and load steady, say with a static scene, increasing Vcore greatly increases power due to V^2/R = P.  Thus heat goes way up.  However, R is a not fixed resistance or an impedance graph, it's the complicated load of a processor.  Sometimes it just needs more power, sometimes it needs less, depending on what it's trying to do.  Yes, you can make it clock high at low voltage which will keep it in different range than stock, but that range may include max power without you realizing it.
 
Recommend using Heaven bench in a window and the pause/camera feature, to see the effects in real time.
 
If you have consistent load, you can get the same result with the sliders as you can core clock locking software.
 
If you have an inconsistent load, locking at an appropriate clock and voltage will make the card power down under light load.  Or you can just set low-lag v-sync and a power limit to get the same effect, but more stable and less hazardously.
