So let's say that we take a 1080Ti and overvolt it to maximum while having the power limiter disabled by shorting the shunt, what cooling solution would be able to cool the GPU below 50c?
I have an old Hybrid AIO from the maxwell era that would still work, but I dunno if the 120mm is enough even with two high speed vardar fans.
There's also an option of buying from a 3rd party vendor, then replacing the thermal material with liquid metal (to improve heat transfer, even just by a little). Currently I'm looking at the Zotac AMP Extreme 1080Ti which has a monstrous heatsink.
Below 50C? Well I sometimes go above 50C with an open water loop (all day sessions will bring me up to the ~60C) having used CLU and waterblocks with at least 240mm for each card in my loop and another 360mm rad that also takes care of an OC'd CPU included in the loop. So those cards technically have over 240mm rad space each.
Yes my cards are Hawaii that may be putting out more heat then the 1080Ti (not really sure on that) but I suggest you need to be thinking at least a 240mm if not a 360mm rad if you want to get close to 50C.

Only stressing my GTX1070@2000Mhz with a benchmark like Unigine Engine i reach temps of 44-45°c that is with a 360 slim rad crossflow. But i have a rad that isn't efficient as a normal one and the CPU is in the loop, so probably a with a better setup i can stay arround 40
A 120mm AIO fell short for the performance you are looking for, but you will still have good temps around 55°c

Just for context i run my 980 Ti on my custom loop (Albeit a crappy one) and it maxes at 53C with 1443 mhz and 1.212 vcore. Before i started pushing my CPU it would max out at 48C. Mind you this is in a very bad loop. There is a lot of constriction because i basically have a Z in the loop. The case i have is also super bad for airflow. If i had a better case, and better flow in my loop it'd probably be at 48c. If the loop was exclusive to the GPU i would suspect temps wouldn't exceed 45c. This is with a bigger GPU 601mm2 compared to the 471mm2 on the 1080ti? If you go a custom, or AIO 240mm i think you'd be under 50c as long as you have the airflow.

I should have a 1080 Ti SLI under water no later then tomorrow and may or may not be shunt modded.
Once they arrive today, I'm going to test them with the stock FE air coolers to make sure they work and to see if the shunt mod will be of any benefit. If so, I will do the shunt mod before installing the blocks.
For reference, my current 1080 SLI has only ever seen 40c or 41c once when my ambient temps were extremely high. With my ambient temps around 20c to 22c, my 1080 SLI is usually in the mid 30s or lower under full load with OC and voltage.
My loop is a bit larger then most. 5 x 360mm rads.
To stay under 50c you're looking at a custom loop. Even on an open bench the zotac is not going to be able to stay under 50c at full load. My zotac 980ti could keep it under 65c with fans 100% at full load but 50c would have required seriously low ambients. You could build a custom shroud for some high speed delta fans and probably hit your temp target without going water but I really don't see the point.

It's going to depend on how much air you're moving through it. The zotac is one of the best air coolers I have messed with if you feed it with cold air you're going to get really good results. Your delta for 50c is really low even with two top of the line 480 rads I peak at 53c with a 22c ambient.
Ambient temperatures in my home office are 30 Celsius in the summer. I live in Texas. I think the highest my GPU (980TI Kingpin) has been is 42 Celsius. Waterblocks are Bitspower.
The only way I could imagine getting temps below 51c without water cooling is to put your system in a refrigerator or freezer.
1080ti has lower TDP than a 980ti so I expect it to run a few degrees cooler.

Might be worth a new thread as we are getting a bit off topic. But thickness generally allows for more surface area with more fins. It's a balancing act to keep noise low while getting the cooling you want. Could I strap my server fans on my rads and drastically lower my delta t? yes but for me the noise is not worth it. Thicker rads are still a function of cfm and surface area.
I just picked up an EVGA 1080 Ti SC2 Hybrid, I've not pushed it too far yet but at 2050 boost the highest I've ever seen it was at 49C and that was after a long session in 77F (25c) ambient. The water block on this card also cools the memory... it got to 51C. Solid card, happy so far and looking forward to pushing it further as time allows.
You can pull it off with an EVGA Hybrid kit, but you're going to have to get some fast fans to keep it under 50C. My Xp with 2x Silentwings 3 (low speed version) in p./p keeps it at 60C with +100mV on the vcore (locked at 1.093v) and a shunt mod at 4K (4k draws more power and thus higher temps than lower resolutions). However, from 50C to 60C, I only get a single bin drop. So, instead of running 2050, I'm running 2038. Hardly a noticeable difference.
From my experience like EVGA Hybrid and aftermarket air cooler Raijintek Morpheus II and custom water loop on few cards
Older EVGA Titan X SC with EVGA Hybrid temps, my best temps has been in 60's or high 50's that's with 1469MHz OC
With Raijintek Morpheus II and Titan X SC with 1469MHz OC my temps has been in 42-45 °C under heavy load in rendering or gaming
Under water Titan X SC I've never seen higher temps than 32-34 °C
Currently running 3*GPU(GTX1080Ti and 2*GTX1080) and temps on GTX1080Ti are with 2126MHz OC are in 32-36°C region, but mostly sits at 32-34°C during the rendering or gaming
With both GTX1080 my temps are pretty much around 2-3°C lower than on Ti,both GTX1080 running OC(first 2164MHz and 2100MHz respectively)

Yup that's correct, have similar experiences with CPU cooling when I switched from H100i v2 to NH-D15 and I've got better temperatures with NH-D15 than with H100i and higher OC as well with NH-D15 I could run with H100i v2
Raijintek Morpheus II, Kraken G10 or G12 with Corsair H90 (140mm) or H105 (240mm), EVGA Hybrid Kit or Chill Water.
Slap on that Grizzyl Kryonaut or Conconduct (liquid metal) and you are fine.
If you don't want to build custom loop those are very good options.
