Not sure why you say that the XT is only good for 1920x1080p when its clearly capable of 2560x1440p Ultra at 70-80 FPS in nearly all cases and will shoot over 100 FPS with a few small settings tweaks down to "High". And these aren't even the titles that favor AMD lol.
 
As my linked thread earlier shows, its even capable of a smooth experience at 3440x1440p high settings, but I would recommend Overclocking the card at this point to really make it a fully desirable experience with better 1% lows.
 
The RX 5700-XT is hardly any slower than the RTX 2070-S. We all know this already, they are both 1440p gaming cards. Im not sure why people still don't understand this. If a card can hold a stable frame rate over 60 FPS with 1% lows at or above 50 FPS, then the card is a perfectly reasonable choice designed for that game at that resolution and those settings. Its as simple as that.
 
I mean Im currently 2560x1440p gaming at medium/high settings on a MSI Twin Frozr GTX 980 4GB and Im getting 70-80 FPS. I mean yea it could do High settings with a drop of a few frames but the VRAM is the problem. So even the GTX 980 is VERY NEARLY a promising 1440p card and its about 40% slower than the XT with 25% less cores lol.

I just ran it at stock, and Vram topped out at 84C. The heatsinks and shims come with adhesive tape. I'm not sure if it's 8810, but I'm sure it does an acceptable job.

I bought a 5700XT and slapped an Accelero Xtreme 3 on it and have tons of thermal headroom to overclock the GPU, reaching pretty comfortably up to 2100 MHz below 90C hotspot at lower framerates, 2000 MHz at 95C hotspot at 144 FPS. But the memory, oh the memory. Even after installing custom copper shims with additional heatsinks, the VRam reaches in excess of 95C, closing in on 100C during stress tests. What's the reasonable limit for GDDR6 VRam?
 
Any ideas for custom cooling the Vram?

So I bought some copper shims for the Vram, and some 14mm copper heatsinks to place on top of them. This is mostly to cover the chips that are blocked by the gpu bracket on the Accelero Xtreme 3.
 
 

 
 
The section in blue was particularly problematic. The heatsinks would not fit under the GPU bracket:
 
 

 
 
I ended up having to extend out another layer of base plate and tweak the pins an embarrassing amount. It's completely jank, and I'm not proud of it, but I had no choice.
 
 

 
 
The other heatsinks needed to be tweaked as well to fit under the GPU heatsink, but I was able to make those look much nicer. So was it worth it? Stock settings with no Wattman, I was getting around 82C-84C, but any overclock shot my Vram temps up to 100C and would have continued if I let it. I was able to achieve a 5553 score on Superposition by overclocking the Vram, but I don't want to talk about the temps I put the card through doing that.
 
This is with no memory overclock, but max GPU overclock (2150 MHz), power limit 50%, at 1.2 volts:
 

 
 
So all in all, worth it. But temps are still way too hot, and I don't think anything short of a waterblock would solve the problem entirely.

Okay well at least in real-world benchmarking, like Heaven, it stays reasonably cool, around 80ish.

When I studied for the CompTIA A+ certification (never finished, but that's beside the point) the book went over the fact that damage to electrical components can occur from static shocks that are so low voltage that you would never know the discharge occurred. And the worst part about this is that these minuscule discharges often don't manifest as complete component failure, instead they manifest as phantom errors, shutdowns, and random crashes. You'll spend forever trying to figure out what setting is wrong or what configuration is set improperly, and you'll just be chasing ghosts.
 
Every time I work on an electrical component, whether it's a GPU, a motherboard, or whatever, I use a strap. In a pinch, you can simply get situated, ground yourself by touching bare metal of a grounded object, then clamping on to a metal part of the component you're working on. That way, at least you'll be at the same potential. Ideally I'd plug in my PSU and clamp to it.
 
Just my two cents.

Semiconductors begin to malfunction at 100 Celsius. 

Micron rates theirs to work from 0C to 95C. For lifespan I'd keep them below 80C

As someone who works in the electrical industry, a backup generator with ATS, the wiring, additional labor to install, whatever you throw at it, will never cost more than what was lost here. It is routine to have these backup generators even in uninteresting projects like apartment buildings. At least here in the states. I can almost guarantee that there was a malfunction in either their ATS or generator.
 
They would only need a short-term backup battery bank in the range of seconds before the generator took over, so that wouldn't have been the problem. If the short-term had failed, the outage would not have lasted 13 minutes, it would have lasted seconds.
