Not sure about how the Nvidia card performs in the wild, but I'm getting pretty solid performance so far from my 2080 Ti XC Gaming, received a few weeks ago on step up from a basic 2080.  15.4K Timespy gpu score set at 116% power, +120 clock, +1001 mem, temps in the mid-high 60's with max fans in a 20C room.  Samsung memory btw.

Usually run it at 105/50/500 with flat 25% fan to 35C, then a straight ramp to 100% at 65C. Hovers around 60C gaming in 4K 60hz with vsync.  14.5K Timespy gpu with those settings on max fans with temps in the low 60's IIRC.

Runs at 56C at 100% power with max fans in a 20C room with two maxed generic 120mm fans blowing on it from the side.
 
Going to put a hybrid cooler on it any day now.  With a single Noctua NH-A12x25 at 1700rpm (still quiet) as an intake on the radiator I'd like to be able to run it about 50C with the 116% (300w) power limit setting, maybe higher boost clock, for everyday use.  The factory bios will go to 130% (338w).

Thanks, good temps.  I'll have to see what the nVidia 2080 Ti is pushing.  They sound like they're 2000rpm+ on default.

I would not say it's very bad noise, but definitely it's not silent.
 

 
I didn't read a lot about RTX2080Ti but only I hear is that EVGA RTX2080Ti FTW3 have very silent fan.
But it's big card and cost more.
 
If only silent fan is option then you should consider buying Hybrid version or FTW3 version with lower clock. It's 200$ cheaper then original FTW version.
But you must know that many of them have lower clock because can't be stable on frequency of more expensive FTW3 model.
 
 
 

 
 
 
 

Seems in this day and age if you want silent running computers then you need to buy a laptop or use the Integrated graphics.
You can also use a Better Computer Case with Good Air Flow and Keep the Side Covers On and Installed.
And not having the Computer Case a Foot from your head, or sticking your head in the Computer Case.
This helps as well if you have sensitive hearing (Hyperacusis).

This video shows nothing, it is like sitting on top of your Air Conditioner's Outside Condenser.
Or even sitting on top of your Car Engine Driving down the road.

That would be Coil Whine, one sound that I cannot hear.

 
All I hear are Fans and Fingers Snapping
