As others have said, the Titan X EK waterblock fits perfectly. I had a Titan X Pascal before selling it and buying the 1080Ti to save some money, and from what I can tell, the boards are near identical. The biggest difference I could see was the missing VRM. Not surprised at all the block fits perfectly. Temps for me were idling at 30 (warm room though), hitting low 40s in heaven with a +500Mhz overclock to memory, and +140Mhz to core. Tbh it overclocks better than my old Titan, not bad lol.So one of 2 things are going to happen.
1. It's going to blow up and I'm going to buy everything again as i drink my tears.
2. It turns out fine and i keep doing it as my wallet gets destroyed.

Looks like I need to whip the block off & check contact with the card as temps last night while playing Doom hit 89c
Idle temps are fine at 24-25c so I'm guessing the core isn't making good contact.
89c on water!?, highest I could get mine to last night was 30c after a hour of playing Wildlands.![]()

From a stock FE on air to a watercooled one around 2100mhz you're looking at about 20% I'd imagine.
Don't think I'm going to watercool until it's warmer as it's going to be about £400 for all the kit I need.
Yeah. I looked at watercooling this time as well, but was put off by the entry price. It's cheaper and easier for me to stick with my AIO CPU cooler and go high-end air for my 1080 Ti, with pretty much nothing lost in performance either.
Your locked on the power to the card (core), it simply won't let you give it enough juice to fry it.Or black bits from the burnt card? Ha
Did you see the guy spending £600+ W/C his cpu and new Ti? Crazy **** man!!
I get it, it looks really nice and performance is top notch. Understandable too if you have a loop you've built up over time and you're only changing blocks with each upgrade... But from my perspective it's just not worth it, there's no real performance gain for the outlay for me.
