Anyone can point out any review or bench or give any other opinion on this?
I will probably add two more EVGA titan SC to my rig, ofc with updated PSU as well but a bit considered 
with temperatures for 4 of these stacked together. 
There is pretty good airflow in my rig right now at least I think so...
These 2 babies at full run 1050mhz core stays at max of 65-70 degrees right now with tweaked fan curve to jump[  in a bit faster and earlier than default.
Wondering if it would be a problem with 2 more of these added to rig and staying on air cooling?
I'm not really into water cooling, never did custom builds before beside CPU water cooling kit, so I wouldn't really wanna start with titans without practice :)
Thanks

I am currently on tri-sli with SCs and have been contemplating adding a fourth card. I have decided against it on the grounds of performance above everything else, clearly it is slower in some games, and only marginally faster than three way in others. I don't think the extra heat would be a problem in a large case, I have no problems with heat in my Cosmos II case with three cards.

I found this and this; note what makes both reviews unique as hints for how and which games allows four Titans to shine.
 
The following is my [somewhat ignorant] opinion since I don't own four-way SLI:
 
Of all 4-way reviews I've seen over the years, most indirectly betrayed the graphics cards by testing relatively low resolutions such that the fourth card doesn't add anything leading people to believe the fourth card is a waste. Might as well be a bias by the review that happens to see 4-way as a waste.
 
For Titan and GTX780, most reviews limit testing triple-1080p-- which is ironic, who drops $4000 on graphics only to get $600-700 worth of monitors in surround?  Only extreme total resolution will properly scale four Titans, I wouldn't dare waste awesome on regular resolutions.

We all know what happens when you add a second card for SLI and performance doesn't improve as expected, the culprit is usually a stock CPU or a low resolution.  Well that logic doesn't somehow change just because we add more graphics cards or already overclocked the CPU.  For any review, if you see the difference between 3-way and 4-way as marginal, it means scaling was held back by something (either the CPU overclock wasn't high enough or the total resolution wasn't high enough)-- but for some reason everyone blames the fourth graphics card as if 4-way SLI is a waste.  
 
If anyone can't afford more total resolution or afford better CPU cooling to crank that overclock even higher, it isn't the fault of the fourth graphics card.

He's using it for rendering...  I'm not sure what the block of text you posted is supposed to mean.  I tried reading it over and over.

so yes again, I'm using it mostly for rendering. right now even after couple hours of rendering both cards are not going over 50 degrees. also game as well and then it doesnt go over 70 degrees. 
'Finaly I do have a lot of fans getting air in and as all titans are with stock coolers that are using inside air and all pushing out that kinda works fine with current air flow setup again. 
well anyway I will have a chance to test it pretty soon I guess, should get new cards by the end of the week or over weekend if everything goes smooth :)

So, did you manage to run 3 or 4 Titans without water? I'm waiting for my two Titan X and thinking of buying one more later and yet there is no info about runing there cards without water.
And if you managed to do so, could you make a picture of your case and the instalation place?

Thanks for the info. I also saw some benchmarks, and most of them were good. Yet, I was worried these tests ran on a benchmark PC units.
