rotated the heat sinks so that airflow runs front to back (as opposed to pushing it down on the 780ti or up toward the solid panel just above it).

The first card goes right up against the heat sink (at best a millimeter or two away) although its fan faces toward the second 780ti. Those are literally no more than 1mm or less apart betwen the fan's edge and the bottom of the next card; same for the separation between cards 2 and 3.
I plan to try inserting a spacer to see if that will at least stop the fan from making contact

I need to amplifly cooling above stock at least on cards 1 and 2, as a mere 15-minutes in BF4 with all eye candy had the cards at 97c, 93c, and 58c respectively during tri-sli and ultra settings. It was crushing on frame rate even at those settings to a single 1080p screen (awaiting 3 x PG278Q on backorder which is the real reason I have 3 780ti's). I know heat wouldn't be an issue with two 980s which is a potential option but I'm not sure that could drive 3 1440p 144hz monitors effectively with eye candy, and I had bought the 780ti's just over a month ago. >.< I need 3 total displayports (which is on 1+ 980s or on three 780tis collectively).

So far, I have added minor plastic spacers on one side which stopped the contact but not the temperatures. The first card was hitting and throttling at 99 C and the second was around 95 C while the third was in the 60s.
I have since added an extra 120mm fan (secured in mid-air by wire ties...not pretty, but functional...so that it spans across the exposed ends of all three cards blowing towards the rear of the chassis. This lowered sustained peak temps by 10 C across the first two and perhaps 3 - 5 degrees across the cooler one such that the cards don't throttle and peak around 89-90, 83 - 85, and 58 - 63 respectively. Still high, but considerable improvement. We do plan to optimize it further, but it looks like I need to send one card in as my 3 x PG278Q monitors finally arrived and I found that the display port on the first 780ti doesn't work. 😞

1st, drop the plastic spacers and use wood instead (Thats ABC of hardware)
2nd, for temps, some of us were really in to the temp issue and what we found out was this:
there is only 2 ways to lower the unlocked cards temps:
1 - get a liquid cooling system for the cards
2 - (this is the best way to go for fans) USE GPU-Tweak for making a Fan Profile. these unlocked cards have a difference of 18c-23c UNDER LOAD between the CORE & VRM (that means, if the core is at 82c then the VRM will be 100c). what you want to do is to keep your core temp under 82, and to do that use GPU-Tweak.
here, this is mine:
