Tri 780ti SLI on fire

Either the AMD guys are more mature than the nvidia guys when it comes to heat jokes or they are not out of bed yet, i come in here fully expecting to see a few jokes about heat etc :)

Those cards do look awfully close, are they supposed to be that close or are they sagging a bit in the slot making them sit closer together?

Dual slot coolers always sit like that unfortunately. Heat jokes are fine but not when someone with three cards is having difficulty with them, that's just unfair! ;)

The strange thing about using four of them on air was card no.1 still managed to get warmer than no.2 and 3 which were in the middle.

I think it's because the heat generated of the PCB (aka heat from the back of the card) slow rises and saturates more of the air circulating around the top mounted GFX.
 
just throwing it out there but would it worth swapping them around it a bit in case some run hotter or cooler than the rest so the warmer running card can be placed at the bottom
 
Finally the green team are taking some heat about their top-end cards, :P

The top one is not hotter because its a hotter card, its hotter because heat rises!

what mean by it is you can have 3 gtx 780's and individually thay could all run at slightly different temps simply due to different amounts of tim applied, I cant see how every 780 made will run at the exact same temps

That is strange. Was always the middle card with my Titans and same now with three of them, which obviously just makes sense.

Last night after a long stint of testing new drivers, overclocking and benching with no real breaks in-between, mine were roasting :). But they all throttled down on stock fan profile (next to silent) to 550Mhz on each core to maintain the target. So how the OPs have managed to reach those temps is a mystery
 
why spend a fortune on the graphics cards and slap them in a midi tower where airflow space is at a premium anyway? only things you can do is use more fans or bit the bullet and get a case that can offer the air flow that you need

the 600t is an excellent case for airflow.

the problem is that the cards sit so tightly together, a full tower would make no difference.

meaning I will need another fan on the side probably

Also place a 120/140mm fan behind the cards ! Air fromw the fan will find its way into the heatsink profile from the rear and that also helps ! (see my pics - I've used this method since 2009 for all my 3 way SLi setups with reference coolers, and it helps).

Take a side fan than can produce a high static pressure ! just like the ones you would chose to water cooling for radiators. The air will get directed into the tight spot between the cards !. I've been testing this out for my own 3 way setup.
