Yes, I'll have to admit that so far the 1X Titan X HC is Benching very well.
Once the other three arrive (Hopefully before this weekend) then more testing will be done in 4-way SLI.
 
 

Sounds good, looking forward to seeing the pics of it in action.  How cold can you keep 4 running at under load?  That is a lot of wattage and heat to dissipate.  Or does your chiller have a lot of unused overhead?

Don't know exactly how this Old Original 5000 BTU A/C Chiller Conversion I made YEARS Ago in 2008 for my GTX 295 Quad-SLI setup will do trying to maintain/hold low temps with these HC's yet, But the good thing is if it isn't cold enough I can always build a Bigger Chiller by going down to Walmart and buy a 10,000 BTU A/C for a few hundred $$$ and make another conversion! LOL 

Oh cool (literally), it's a frankenchiller!  Is it the really ghetto type with the condenser sitting in an igloo filled with antifreeze?  I was thinking before it was one of those enclosed models like what they sell at Performance PC's.

Yep, A/C Conversion with the Condenser in an Igloo filled with antifreeze using a submersible Pond Pump with a high flow rate using 1/2" flexible tubing.

Has Always worked great and didn't cost $1400 - $1500 like the Performance PC Water Chillers.
You've seen the Pic in my Mods Rigs, Right? It is just one of a few Chiller "Monsters" I have created, including one that I converted from a 5 Cu Ft. Deep Freezer that REALLY went Sub-Zero which unfortunately I don't have any more.
 
 

I think I remember watching that setup being built from your build log you did here way back when. 
Unlike some of the igloo chillers, at least yours has a lid lol.

Well, It HAS to have a lid to totally insulate the Cooler or it would be thermally insufficient at reaching very cold temps.
 
I usually run just above the Dew Point to prevent condensation on not only the tubing, But also the Water Blocks on any of the Graphics Cards I have used now or in the past.
 
Yeah, I have run sub-zero before with the lines/Water Blocks COVERED with Ice, But the Extra few lower temps weren't worth all the trouble. It is like using an DICE/LN2 Pot with No Insulation and That's Not Much Fun at All! 

Well, it should always have a lid, doesn't mean I haven't seen pics of people leaving it open lol, and I would imagine it would still get fairly cold.
 
Since you keep it just above the dew point, is it controlled by a thermostat, or some type external controller?  If you go to Sears and get one of the BIG units, like 16k BTU (biggest window size I have seen there) and used that, how far below zero do you think you could get and would it be sustainable, or would that be running quickly into the same issues you have run into with Phase in the past?
 
I have thought off and on about running a chiller, so now is as good a time as any to ask questions

If you look in my Mods Rigs Pic of the Chiller, you will see that there is an adjustable mechanical thermostat (top left on top of the Condenser) I have wired into the circuitry that cycles the compressor to control the temperature.
The original A/C control panel (Bottom left in the Pic) is still used to start/stop and adjust Condenser Fan Speeds.
 
As I mentioned before in the previous post, There's not a problem of getting sub-zero and maintaining those temps under load, It's just going through all the necessary preparation (ESPECIALLY with Full Cover Water Blocks) to insulate all the hoses and Graphics Card PCB's that becomes a PITA, Which is why I run just above the Dew Point temps in my Home Central A/C Controlled Benching Room!
 
Even when I was using Phase Change Cooling on ONLY the GPU on my previous Nvidia Titan X and EVGA 980 Ti Classified, I still eventually after long operating periods had water/condensation issues around the Evaporator Housing where I had to dismantle it from the Card to remove water build-up.
