Having difficulties with a triple 290 setup

[Chief Thunder]

Hi all! So i finally built it... my first ever water cooled setup, expanded from a swiftech H320. everything worked great, just like in all the tutorials and guides till I ran the valley benchmark. The temp in my middle card went from 40 to 92C in like 5 seconds...so instantly shut the comp down. figured could be an air bubble, and did some more bleeding ( i read air bubbles work out over time) and set the pump to work at full blast. now it's much better, but still rises past 80 but stays there for a while. doesn't shoot upwards like before within a matter of seconds. But it's still pretty high given that the bottom and the top cards idle at around 40 and goes to around 60 under load. they rarely change from one another, which is exactly how it should be considering it's a parallel setup. I've attached a picture here, is there anything you guys can think of? bleed more? bad mount? wrong parallel assembly? the loop order is this:

 

pump>GPU's>CPU(with swiftech pump/h320) >140 rad>360 rad> 280rad>res

 

Cheers!

Remount the block on that card.

Re-seat the block on the middle card

 

Edit:

Nice setup btw

if so as the others have said re-seat the block on the middle gpu.
