The second card will block off the center fan....What little airflow there is will be heated from the backplate....Vrms will sizzle. Cores wont care.

I'm pretty sure that's something they suggest with any multi-GPU config, but it will almost certainly work fine without any open slots.

Step 1. Come up with excuse for 'broken' cardsI'm really starting to like this card, but I'm not sure I can justify it since I do have CF 290s.........first world problems are kicking my butt.
AMD stated 1 open slot required between cards. Read it it one of the reviews or AMD's site. Guessing it's for the vrm cooling.

There are so many things wrong with that setup that I don't even know where to begin. The card spacing is a secondary issue compared to the fact that they're using the 295X2 rads on intakes. That's 1000W of hot air going into the case.Are you so sure? :hmm:

How can you tell its intake? The 120mm fan could simply be pushing air out the front.
I have a similar setup with my Nanoxia, all my rads are pushing hot air out, with fresh intake from side and bottom.
I would be concerned at the lack of airflow for the VRM fans, they already get hot at ~90C under load, definitely better to have an extra slot between them.
Judging by the placement of the fans all of the radiators are exhausts and the rear 120mm is the only intake. Its very rare to not use push and instead use only pull to move air through a rad. If they where all intakes every rad would be pulling air through instead of pushing. Not likely.
Also, notice that shroud has open. Slots on the sides which should all the fan some air intake. Probably not ideal, but also not blocked off.
That's a good point that I had not considered, and VulgarDisplay seems to have answered it. Which means it's not quite as awful as it first seemed, but I'm not sure this is much better. The "right" way to do it would be to use a single 120mm for the CPU, and then place the GPU 120mms at the top and back respectively. This would allow cool air to be drawn in the front and out the rear.How can you tell its intake? The 120mm fan could simply be pushing air out the front.
The 295X2 uses an axial fan. There's no real possibility of pulling in air via the slots in the shroud, as the only way that fan can move air is by pulling it in from the space on its intake side.. So those slots are for exhaust purposes.Also, notice that shroud has open. Slots on the sides which should all the fan some air intake. Probably not ideal, but also not blocked off.
Almost all blower fan setups have the same "issue" (other card blocks the blower fan) yet they still run alright. It's not ideal, but it shouldn't lead to VRMs blowing up. Besides, the VRMs on the rear get hottest anyways and the extra airflow from the other card next to it's fan may actually help with that.

No. Looking at your rig I'm guessing your more of a cooling guru than me.
I bet you wouldn't put a solid object in front of your case fans tho
See you beat me to it when I was searching for pictures. Visualizing it is hard for some.
