I purchased a 1080 EVGA hybrid cooler off Ebay to see if it would work well with the 1080 Ti. I was actually impressed and 100% satisfied at the results. This will be my setup until the next series of cards come out.
 
I paid $30 shipped for the used hybrid cooler.
 
 
With Furmark i was hitting around 80c with max fan speed on stock cooler. With the hybrid installed my max temp is 59c after an hour. This is with +200 core and +500 mem.
 
I have the stock Nvidia fan at 20% speed to still cool the VRM and the rest of the components that touch the stock plate. 
 
Thanks goes to Gamers Nexus.

You do not need to disassemble the entire card. Just the top part of the shroud.

 
When all is said and done the only parts missing from the 1080 ti is plastic window and 4 screws that hold the window along with the heatsink.
I also removed the cap EVGA cap to the hybrid cooler. 

nicee thinking of doing this!

It looks like the top part of the shroud is what is holding the cooler in place. Is this correct? Does it stay in place without sliding with the vibration of the card?
 
And nice work!

Oh well that's good to know! So one could simply buy the 1080ti and the 1080hybrid kit then just wait for the official shroud to be released or something like that. I'm sure kany will follow your footsteps.

The cooler mounting holes on the 1080ti are exactly the same as the 1080. The cooler is held on by the original 4 screws that held on the OEM heatsink. You don't need to put the shroud on. The shroud is there to help direct air over the entire card. VRM and other components are still being cooled.

That is a totally sassy looking PC very beautifuf and very clean, the way it should be. Mine will be clean shortly with new parts like a New 240gig Sandisk SSD-drive that will power my Win-10 OS, i hope that will make things better for right now. I love that that Awesome Hybrid-build to, good temps.
 
Don't forget to Post us your results, this is awesome heheh.

For information purposes which hybrid kit did you get ?

P/N: 400-HY-5288-B1
P/N: 400-HY-5188-B1

???

I used the 5188. The ftw (51288) model has copper fins for the VRM. The vrm  placement is a little different on the ti. I would not suggest the 5288 model

Nice! What kind of boost clocks are you seeing while gaming?

a little less than 2100 max in BF1

how is it treating you? good temps i assume.

I have yet to pass 60c in game. My fan curve is mildly aggressive with push pull TT riing 12 fans. Noise is low especially compared to that stock nvidia cooler at 100%. God i hate that stock cooler noise.

You didnt have the hybrid shroud im guessing?

I have the EVGA shroud and the EVGA plate. They do not accommodate the 1080 ti PCB with out modification (cutting). I could make the modifications to the EVGA plate, but I don't see the point for my tastes. I like the look of the reference shroud and everything on PCB is being cooled adequately.

Sold. Didnt want to wait to use my EVGA bucks ;)...since they exp on the 15th(tomorrow). grabbed a aio kit for $.99 + shipping since you can use it toward shipping  
 
BTW, that cap to the AIO pops off easy?
 

Yes the AIO cap pulls off with a slight squeeze and pull. 
 
Here is a video of the Titan X Pascal using this EVGA cooler. The Titan XP is almost identical in regards to cooler/PCB minus the dvi port and a few things here and there. He takes apart the entire card for the sake of the video, but you don't have to. You can also turn the cooler with the tubes facing the io plate and remove the cap to put the shroud in place like I did. 
He makes it look more difficult than it is, but he is also doing it on camera.

Love the sleeved power cables!  Did you do those yourself?  I'd like to try that on my new cards when they arrive.
 
Are they difficult to make?

I bought extensions on Amazon.

BTW, your case fans...fan rads pushing out, top fan pulling in?

What about cooling the actual memory units next to the processor? Is that going to be a problem? The blower fan isn't really going to cool those anymore. 

Was thinking the same, but the mid plate is there. I guess if the memory isnt OC, shouldnt be a problem.  Even the AIO kits that fit the 1070/1080s use the blower fan.  On this mod, the air will escape where the die is, but still shouldnt cause to much extra heat on the ram near the back.  I imagine you can cover that open area and the air will pass over the backside of the mid plate.

The original thermal pads are still intact on the PCB (vrm and other components). 
I have a 500mhz overclock on the ram.
I keep the blower fan at a 20-30% curve. I still feel air coming out the back io grill. I would say around 30-50% of the air still passes over the entire PCB plate.
 
If it's a worry for you, the open area can be covered easily. 
 
For me, I believe the setup is adequate. The orignal heatsink didnt really do much for dissipating the vrm heat except block the air. 
 
 

Noise was my issue also. Below 50c I'm at 20% blower speed. And above 50c I'm at 30%. So only when gaming.
 
To answer another question, Rear and top case fans are all exhaust.
