Everything is one loop in my system; single reservoir and one pump. There is no point in two independent loops, imo, unless it is for aesthetics and wanting two different colours of coolants in your tubing etc. The main idea is to have enough radiator for your heat output. I think a 480 rad could just mange two 980ti and your CPU, alternately a 360 and a 240 would be better and definitely enough rad.
The rules change from vendor to vendor as far as warranty. All you need is an AIB that allows removing the cooler. When you want to sell it you can just put the air cooler back on. I usually try to sell the cards with the waterblocks.
I'm sure they would. Doesn't change the fact that the cooler is a joke if you plan on ocing. I wouldn't buy a b reference r9 290 either. Wouldn't get a reference and with a poor blower. Dual or triple slot cooler and the AIO cooler I may even try now too.I think a Lot of people would disagree with you on this. If people already happily pay $649 for a reference 980Ti with 10% less shaders, a TX at this same price would be great. A custom cooler or block would be pretty cheap to add...
The real issue here is that the original Titan offered more memory and unique DP features not on other GPUs from NV. Now, it just has 12GB vs. 6GB memory BUT is held-back by only using the reference PCB and cooling. I agree this is a pretty big drawback and the TX will be much less desirable for anyone looking to OC once the really good custom 980Tis arrive. I wonder if NV will re-think the Titan strategy to allows for more customization? It would be relatively easy to offer the same board SKUs we will see between the TX and the 980Ti if it was allowed.

OK, so one pump, one reservoir but possibly two radiators. Does the size of the reservoir matter? Does it help cooling performance to have a large pool of liquid, or will it work just as well if you barely had enough to fill the loop and with only a small reservoir?
I'm excited about getting 2 or 300 more Mhz on the CPU, adding enough boost to the 980TI's to match or beat all the aftermarket cards and to do it all fairly quietly and looking sexy as hell to boot.
Wow, over 20% more than a stock 980 TI. Scaling is amazing. Power consumption out of the box is barely over a stock 980 TI, too.

GM200 is really held back by the reference blower. Look at the cut down GM200 demolishing Titan X!
OK fine. You guys convinced me.
::Water obsession mode activated::
I'm researching a new case and my first ever custom loop. Gonna cool this sucker DOWN. I want it all quiet though. Is that possible for water cooling? To get cool and quiet? Also, I wonder if my enermax revolution 1050watt will be enough with some added OC to cards and CPU. I won't be adding voltage to the GPUs though. I'm just not comfortable with that. I'll open them up as far as stock voltage allows though.
It's not that simple. The cooler while adequate could be better but what holds back titan x and even 980 ti is the vbios limitations. I've removed them all completely for my cards and use them at 1450 mhz in every single game. Temps never exceed 82C while at that clock and this is with no fluctuations in core clock since i had boost removed.
Really? Overvolt and increased power limit on the stock blower? That's nuts. You better check the back of the card. That thing must be blazing hot. When I was running without a proper backplate, my infrared gun measured nearly 100c on the VRM and over 85c on the VRAM. Might want to be careful. Oh, the noise. I can't imagine how loud that thing is. I'm willing to bet it's over 50% on the fan curve. Probably around 60%.
Hey, its one reason to look forward to old age, right? Noise issues become less and less important.
What?
Wait, that joke works better in person...
moonbogg: I have a Thermaltake Core X-9 case and it has TONS of room for radiators. The "Cadillac" of water cooling cases are Caselabs but very expensive.
I would suggest a single loop for both your cpu and dual gpus. The EK Titan X full water blocks fit the GTX980TI and address BOTH gpu and VRM cooling.
A formula was given to me on this forum by one of the water cooling "gurus" BrightCandle, to calculate the amount of radiator space needed for standard 120 mm rads to cool enough to keep a 10 degree delta between the room temp and your actual loop temp with fans at @800 rpm. It requires you to calculate the toal wattage put out by your cpu and gpus.
120 mm rads spaces needed = total wattage / 130.
I used 250W for my 3930k @4.6Ghz and 300W per card for my R9 290s. If you overclock the gpus, that total wattage really jumps.
In your case, a 3930k @4.3Ghz is no more than 225 W and the 980TI is @250-275 per card. Lets be safe and say 275. 225+275+275=775/130=@ 6 rad spaces.
I clearly over radded my rig but did it because I had the room with the case I have (holds 2 480s in the roof and 1 480 to the side.
It helps though as I jumped to an 8 core/16 thread 5960x I had plenty of capacity.
My suggestion is buy the biggest case you can reasonable afford, both in price and space. It gives you plenty of room for both radiators, and pumps, and reservoirs.
This is good advice. While I really like the look of a water cooled setup in a smaller case, it takes a lot of effort - or using acrylic tube, to really get it all in there neatly.
I use a 900D and space/tube runs are never an issue. The case is too big really and I'd rather something smaller, but it's easier to work with.

hahaha
Now I remember why I stopped coming around here so much...these mofos spent more of my money than my wife.
I can attest to that. The 350D is a great case, but it gets awfully cramped....another reason I would rather avoid SLI/CF if possible. 2xGPU boards (like a Fiji '295x2') with HBM could be FANTASTIC for these smaller builds, especially on water.
Waiting for some professional site to do a review of 980Ti vs. 980 both at 1.45-1.5Ghz clocks. I expect the former to win by 35-40%.
Why it wouldn't be that way? 980TI has almost ~1.45x more resources than 980. Everything is scaled, ROPs, TMUs, mem, L2 cache, memory bw, shaders. Tests show pretty much linear scaling, so it ends up in clocking contest.
I'll repeat it again - 1400Mhz GM200 and GM204 is big nemesis of AMD, air OC extracting extra 25% of perf out of these cores is going to have disastrous results on AMD lineup.

I'm looking at that Phanteks Enthoo Evolv on AT's coverage of Computex with room for two 140s or 120s up top and wondering if that could fit a pair of Furies.
