Major overheating issues

Lol thats a classic mistake right there :)

As said above move the fitting on the top card to the right and put the blank in the left output

I'm not convinced it's going to solve anything as if the flow is bypassing the top card, then the bottom card should be staying nice and cool but it's not. When bottom card is primary, it's cooking as well.
 
I looked at them pictures and was like "Hmm something is wrong it doesn't look right, I'm missing something" then when people mentioned bypassing I was like "Oh yeah, oops"

heheh, I hope it gets sorted!
 
Yes I agree it is Bypassing GPU 1 as it should go in the top and come out the port on the right.

you could make it easier for yourself and put them in parallel like this, that way it will go through both GPUs at the same time.



better flow and few degrees cooler than serial.

They could do that but if they havent got two more fittings they cannot do it,

I just looked online and most people have the inlet on the left and out on the right.

So what i do is more the small tubing to the right ports and move your 45 dregree tubing to the bottom left port.

I'll give that a go, easier than changing it. Still doesn't explain why the bottom GPU cooks when that's the primary GPU.

This would also sort the plumbing with the same parts:

Sounds like a mounting issue, however I think your set up is strange and from experience won't be helping that much:

1 x 480mm roof rad with 4 Corsair fans pulling air through the roof, pushing through the rad (OUT)
1 x 360mm basement mounted rad with 3 Corsair fans pulling through the side panel and pushing through the rad. (OUT OR IN, PREFERENCE WOULD BE OUT)
3 x front panel fans pulling air into the case (IN)
1 x massive exhaust fan pushing air out the back of the case. (IN)

Now I haven't done anything on your scale since the days of 480gtx sli, but it is always better to be pulling cool air in through your fans and pushing their air out through the rads, i.e.

I would be doing this:

1 x 480mm roof rad with 4 Corsair fans pushing air through the roof, pulling through the rad
1 x 360mm basement mounted rad with 3 Corsair fans pulling through the side panel and pushing through the rad. (either way with this one)
3 x front panel fans pulling air into the case
1 x massive exhaust fan pushing air into the case

Your air flow seems unbalanced to me, you are sucking too much air in and not enough out, again best to have it balanced the other way, i.e. suck more out of the case as possible

As a point of reference I used to run two 480gtx and I think an 875k using one ThermoChill PA120.3 on the roof of a 700d and it was fine, I turned it the other way around and all was not well.

Sorry Dazzerd but I disagree with your "Better to have more out than in" regards air flow
I always slightly positive pressure my case (More in than out) or try to balance is as close as possible, otherwise the case will try to suck in air ANYWHERE it can, through the gaps int he case panels, through the front grill edges, through the rear pci covers...
As all my inlets have filters of some kind it also helps with dust control!

I suppose its a personal preference but just wanted to say why so the OP can make up their own mind :)
