So if i get the 1080 and just don't use the shroud, will it definitively work fine and can I install it? I thought the GP102 vs GP104 had other implications? Is that "bad?" Is it just a cosmetic thing?

Yes you can simply remove some parts of the stock cooler and only install the water block. But It will not look as good and some of the air flow that can travel tru the end when the shroud is in place will escape in your case. The shroud is only cosmetic because if you leave the fan on auto and the gpu gets 50 degres the fan will not ramp up really high, so for the ram cooling I dont think it will have a big impact. And it is a lot more simple to use that way. You dont have to remove the baseplate and cut some parts of the new one.
Maybe some thing im gonna do if their is no Hybrid kit design for the Titan X Pascal. 
 
We need to know if its gonna happen. Thats not hard to say.  We are working on it or sorry guys not this time. YES or NO thats it
 
 
+1 for me :)

Some entrepreneurial person should just sell custom shrouds for the Titan X. I for one would buy a reconditioned kit with the shroud already cut if anybody could make one. Feel free to pm me or let me know if you're interested. Tired of waiting. In fact, if you're particularly entrepreneurial, make like 10 and put them on eBAY. I bet you could make a $50-100 a pop for each one plus costs of the original kit - I know many friends who would pay who don't have the tools to cut the shroud themselves

I had a dream last night that EVGA finally released it's Titan X Pascal Hybrid cooler and then...nothing happened

I want to be CRYSTAL clear - if I get a 1070/1080 cooler and put it on my titan x without the shroud, some have said it will have some vram issues but shouldn't be a big deal
 
Does this mean I will be totally fine? If you're really telling me I can do it without the shroud and I'll be 100% ok, both card and vram, i'll buy it today and just put it on without the shroud

The existing 1080 hybrid kit can be made to fit perfectly, shroud and all, with only *minor* and very simple modifications (all you need is a dremel with a cutting disc and a grinder to make to small modifications to the EVGA kit cooling plate). Several folk have already done it and posted guides... I tried to post some good guides but EVGA forums won't let me post a link for some ghey reason ...
 
Otherwise? Just search around overclock.net and you should find the links fine...
 
You can run the hybrid pump just fine without the shroud.  You should find some way to cool the VRAM however as they do get super hot and I'm sure it would, ultimately, affect performance.  There are various ways you could do this ... just find some way to mount a decent 80mm fan over the VRAM ... or even get something like an Antec "Spotcool" to point at the VRAM area.
 
If EVGA doesn't release their hybrid kit for the Titan X soon, I am simply going to mod a 1080 kit ...

One more thing about the VRAM issue ... I use two Hybrid kits on my dual GTX980's and can say that the VRAM cooling performance of these kits is rather astonishing.  Even with the pump assembly somewhat blocking air flow, I measure a consistent 110F degree temp of the air shooting out the back of the cards (I have them set to run at 50% when gaming/overclocking my cards).  
 
Furthermore, when I installed the 980 hybrid kits, I added copper heatsinks to the cooling plate ... not sure if this is helping much but I know for a fact that the VRAM/Shroud cooling works great simply because I can game all day over 1500mhz on core and because the temp of the air exhausting is so hot (about the same temp as the air coming out of the radiator portion of the kit, actually)..

The VRam doesn't get as hot as other components. There are plenty of cards that don't even have hest spreaders on the VRam. The VRM is extremely important to keep cool.

You'll need to earn the right to post links ---> around your 11 or 12 post I believe
 
 
It works fine with the back half of the shroud over the factory fan; unlike in the photo in the above post - keep the factory cool plate to help with heat disapation.

Star light, star bright,
First star I see tonight,
I wish I may, I wish I might,
Have this wish I wish tonight.
