I'm a little confused. I would really appreciate if someone clarified this one thing for me:
 
Would I get better temperatures if the fan of the AiO cooler pushed air into the radiator and OUT of the case (exhaust) or sucked air in from the outside and through the radiator (intake)? I'm assuming the latter?

Theoretically, the air from outside would be cooler than the air inside.  That does mean, however, that you are putting more hot air into the case.  You would need good air flow if doing that.

Hey guys!
 
GOOD NEWS! Everything went well, took me 1hour 1/2 since i really took my time and my tools were outdated, had to be creative for those small screws! So here it is , this installation is FAR from final since i got 5-6fans awaiting shipping from the egg so i'll post an update of the build but right now you can see how it looks.
 

 
And now the temps!
 
I'm running it stock (superclocked) on EVGA OC Scanner Furry GPU Burner 3072mb for the purpose of tests.
 
BEFORE AiO
 
Idle : 35-36c
Full Load : 68-70c
 
AFTER the installation of the 980 AiO Hybrid
 
Idle : 28c
Full Load : 46c-47c
 
------------------------------
 
Conclusion, you can see that it ROCKS. temps are WAY lower AND the pump is near silent in a good case. Sincerely, i couldn't be more happy with this produc. They should've thought of that 2300years ago.

VERY nice.... now those are some lovely results!

Sold out already??

Looks like that Front Fan will push cool air right over the top of the fan mounted on top of the Radiator.
This should bring some really cool temps. Nice Job.

It even looks like you have room to use two fans.

Just for reference: I get Max Temps of 68°C for a Core: 1491 Mhz at +112mV

 
I'm using the SC bios with modded TDP by Sheyster from OCN!
 
Voltage is maxxed but still in the same interval as the stock bios, at least according to Precision X. My ASIC is pretty average also at 67%.
 
I didn't thoroughly tested the OC for stability though... I just gamed for about an hour with GTAV and I didn't experience any crash ( while I did at 1501 Mhz).
 
I'm pretty happy with the result, just too bad for the humming noise, it is really a bummer during night time.

From what was mentioned about the aio pumps being very picky about voltage, I wonder if you over-voltage-ing could be causing the hum?
Maybe try turning off the OC for a few minutes and see if that affects it?

Hmm gonna return mine tomorrow after work. Maybe its my case airflow but for some reason the hybrid cooler is doing worse than the stock air cooler for me. Idle about 60C, load 91C, vs idle 37C/load 80C for the stocker cooler, all at stock clocks. I'd tried reseating the AIO and swapping back and forth between the stock and AIO to see if I was doing something wrong. I dunno, my case thermals must be bad or something. I just can't get good temps with my Titan X in my H440 case using this cooler. 
 
From a freshbootup its very low temp I might add, starts at around 23-24C when I first boot up which never happens with the stock cooler, stock cooler always starts up around 32-33C. But it just slowly starts climbing like the fan isn't getting rid of the heat fast enough. I even tried just exhausting the CLC out the side of an open case but that didn't seem to help either.

Sounds like your pump and/or your fan isn't even working. Pinch the tubes while it's running you should feel the fluid moving. If not working you probably need to open your card back up to make sure you installed the Y-splitter properly on the small 4 pin connector that the GPU fan originally fed off of. That's where your pump gets its juice from + the 120mm fan on the radiator.

Oh I'm sure it's working. My PC is all low rpm Noctua fans with the low noise adapter, and a PSU that runs fanless until 50% load. This pump instantly quadruples the noise of my entire PC :P

Oh you guys, making all this work for me. Spent a lot of time tonight fiddling with setup. I got both AIOs mounted as intakes and it did improve my temperatures. To say that the clearances were tight would be an understatement. I had to not use the included washers to get it to fit. I attached a picture of that. I had to redo a lot of the cable management. The end result is pretty clean I think, but it really took a lot of effort to get it that way!
 
I got everything plugged in and realized that the fan on the bottom was not spinning! Took it out and did some troubleshooting and figured out that the fan was just dead. I'm not sure if it died tonight or if it ever worked at all. I'm 90% sure I verified that both fans were spinning when I first installed them, but I'm not entirely sure. Either way, there is no visible damage to the fan. I went to my wife's computer and stole her 120mm exhaust fan, and the temps are running higher on that card. I'm not going to lose any sleep over temps until I get proper fans going. (I also ordered 2 backplates today!)
 
Which brings me to my question - I think I'm going to get Corsair SP120s and 140s to replace the stock stuff that came with my case. Should I get the quiet edition or the performance edition? I think I would really like a quiet PC, but if it's going to make a big diff in temperatures, I'll go with performance. Any thoughts?
 
Here are my new temperatures

* again, this fan was stolen from wife's cheap Antec case because EVGA one broke
 
** also, I have no idea how you guys are getting 1490 out of your GPUs. [H]ard|OCP reviews said they got +220 core out of theirs with the fans running at 100%. I ran my OC benchmark at 220, but 250 caused me to crash.

Quite simply, single core/thread performance. Almost every single PC game in existence relies heavily on 1 core while all the other 3~7 cores get a pathetic 15% usage or whatever. Even games that flaunt saying "Our game will use as many cores/threads you can throw at it," it still primarily just uses 1 core (Arma 3 for example). Direct X 12 is supposed to 'help' remedy this by "spreading out the load" on all the cores more evenly which is something we've been wanting several years ago ever since quad cores were introduced. I unfortunately doubt this will happen for a long time and would assume the game would have to be built from the ground up on DX12 and not simply just ports. Of course, we have to assume game publishers actually optimize PC games which we all know will never happen.
 
If you look at CPU gaming benchmarks, the $350 4970k almost always outbeats the $1000 5960x in practically 90%+ of all gaming benchmarks due to the higher core clock. You can realistically get a 4970k to about 4.9Ghz w/o much issue. The 5960x you're looking at around 4.4~4.5Ghz good overclock. This gap will become even larger once Intel release Skylake supposedly coming out in a few months. The i7 6700k will replace the 4970k with an estimated 5%~15% performance improvement. This means a 6700k at lets say 4.8ghz will be roughly the same as a 4970k at 5.04ghz~5.52Ghz. Potentially anywhere between 600mhz~1.1Ghz more than a 5960x which is actually quite a bit. For some reason, the mainstream platform always gets new technology anywhere between 6~24 months before the enthusiast "X" platform does. The X99 platform will probably just receive a +100mhz bump on the 5960x calling it the 5970x and will be stuck with this for another whole year.
 
Many older games such as flight simulators and MMO's are about 95% always 1 core games. I doubt we'll see any MMO's built from Direct X 12 from the ground up anytime soon. Even the PC Master Race game Star Citizen doesn't use cores that well. Of course it's still in pre-pre Alpha so not holding it to high standards just yet. Another example, Skyrim only uses 2 cores. For every +100mhz in CPU speed was like another 5FPS or something like that I forgot the exact #'s. For me personally, if I got rid of my 3rd Titan X and changed to a Skylake platform, there would be half a dozen games that will decrease in performance wanting that 3rd card for 4K resolution but at the same time I'll also have half a dozen games that will increase in performance that need more than my 4.4Ghz on 1 core. So it's really a wash but I end up saving thousands of dollars.
 
FYI: my source is I have a little USB monitor where I can see real-time usage on all my CPU cores and GPUs (% used, temps, current clock, ect.). I've tested dozens of games from 2013+ and it's all pretty much the same story. 1 core takes the most load and the rest are not really being used that much. I bought my system when there was no such thing as a Titan X but only 980's. You pretty much needed 4x 980's to get decent FPS on a 4K monitor. 2x Titan X's are roughly 3.5 980's in performance so more or less 4x 980 performance. If I bought my system when the Titan X's were already out, I probably would have went with a Z97 platform instead. Just my personal preference of course. I plan on waiting out Skylake to see what happens. There are games that do indeed benefit from a 3rd & 4th Titan X on 4K.

seyumi's detailed explanation covers pretty much all the important points.
 
Just my $0.02 on the matter: From the research that I've done, I think 4.9GHz on a 4790K is closer to an "epic overclock" than "can hit it without much issue". 4.7 is a more realistic OC, and even then you can't always get that just because of the silicon lottery. Tip of the hat to anyone who went with a 5960X, but it's a very expensive processor and from a bang-for-the-buck perspective, most people go for the 5820K as it's the exact same as a 5930K for all intents and purposes until we start talking quad-SLI. The actual comparison you should be making is something like 4970K@4.7 vs 5820K@4.5, especially since they're similarly priced.
 
For pure gaming, the 4790K is a better processor, and a Z97 setup will cost less than X99 (though the difference is relatively small in the context of Titan X systems). However, it really is so close as to be "a wash" as seyumi said. However, when applications CAN utilize the extra cores, the 5820K comes out on top by a much more significant margin. 5820K > 4970K in BF4, for example. AnandTech has a great article that covers this from August 29, 2014. Sorry, my account is too new, and it won't let me make links.
 
Personally, I went with X99 just because 4790K felt like a sidegrade from my 2600K@4.2. 6-cores felt like a more worthy upgrade for my SLI Titan X's, and I do just enough non-gaming stuff that utilizes the extra cores for it to make sense. Also, all the reviews for the Rampage V Extreme were so glowing that I really wanted to get one!

 
Wow so many posts already XD I backtracked your responses and just wanted to thank you both for your detailed input. I agree that if you OC both then the Z97 CPU's will win on single core performance any day, but I guess personally that difference is negligible, as long as I get the 5930k to the 4.5Ghz area. I'm going to go for thatone because I'm planning to fully utilize the PCI-e lanes with a couple of additions like a PCI-e SSD and perhaps an M.2 version in the future (not possible with the 5820k in some configurations).

Outside of gaming the video/photo rendering/editing speed with a 6 or 8core just wins it for me. I might upgrade it to an extreme edition once broadwell-e shows up, to make the switch to an 8core. If these AIO coolers prove their worth (I'm sure they will), I might also go for a triple Titan X setup in the future.

More on topic: thanks for all these temp posts guys! Truly awesome results. I guess some of the difference people are mentioning are just due to hot air being 'stuck' between the 2nd card and the PSU, or the 2nd card and the 1st card. Also, some folks have a wider cone of air blowing onto the 2nd card from one of the radiators (when they are intake ofcourse). As long as it is a 5 degrees difference on average I don't see it as a problem.

I really do hope that if they release a Titan X shroud, that it looks as badass as the current one on the Titan X. I would pay a little extra for it to be metal like the original one.

Edit: also, seyumi, could you tell me at what fps numbers you are getting microstutter with fc3 and bioshock infinite? and with what monitor? I'm kinda curious about 4k, but I'll stick with my 144Hz Gsync panel for now, and in some cases Gsync is supposed to eliminate microstutter.

I am very happy with my EVGA AIO cooler on 2 of my Titan X.
 
The temp is more than perfect
 
I runs the game such as Tombraider, GTA5 , Batman:Origian all the games never drop on boost clock(1164 , since I never OC the card). During the game 1st Card never goes above 48 degree and 2nd Card never goes above 50 degree.
 
It seems second card is hotter than 1st card. But never mind since both card never will reach near 80 degree.
 
I was just wonder do you guys use other fan instead of EVGA fan?
 
I currently switched to Corsair SP120 quite edition one but since I connect the power to AIO cooler power if the temp goes above 40 degree the fan start in high RPM it makes noise.
 
Is it OK if the put the power on motherboard and put the fan speed as silent constantly?
 
Anyway I bought new Antec P380 case to minimise the noise as well.Cant wait to see the case.

I run Bioshock Infinite at vsync 60FPS on my 4K monitor. There were a few scenes where my 2 Titan X's would go full 99% load and the FPS would dip below 60FPS so then I put a 3rd Titan X in. I immediately noticed a horrible difference. I was now getting a 100% consistent 60FPS but the game felt horrible like I was getting 30FPS or something at ALL times even though I was technically at 60FPS. After some research it looks like it's some form of SLI latency and people recommended using a frame limiter. This actually worked for me. I had to use a 3rd party program and limited the frames to 58FPS (needs to be below the monitor hz to counter vsync lag). The game was now smooth again just like when I had 2 cards. There were times where that 30FPS feeling came in but it was only for a few seconds. Not as consistent as just using 2 cards but was at least bearable. Farcry 3 was similar but my FPS was just all over the place when I went from 2 cards to 3 cards. The frame limiter helped but it was still more consistent on 2 cards. I'm sure this is just a problem with these games and their SLI profile to be honest. I've played about half a dozen other games and don't experience this (FFXIV, Tomb Raider, RE6, Sniper Ghost Warrior 2, Saints Row IV). I hope I don't run into anymore of these issues on my dozens of other games I haven't played yet.

Hey
 
do you have a cpu overclock ? i remember seeing a youtuber jayz2cents ? having problems with 3 cards because his cpu overclock was somehow bottlenecking the thrid SLi card. Check this out.

Hey
 
Most people have all in one screwdrivers/torx/whatever kit. These most likely have everything you need BESIDES the small screws which are phillips #00 or 000 not sure. But damn they're small.

I would say that the above setup is the Smallest I would go with Two Cards. Though I would recommend a larger Case for best Air Flow.
I added Links to you above images to we can see the org file to zoom in. Click on the ABOVE IMAGE for a Larger View.
You should be fine the two bottom fans.
 
Each Card will Overclock differently from others, no two Graphics Cards are the Same. It is all a Gamble.
