good evening everybody:) im a 3d artist and for rendering, im currently running 2x2080 ti asus turbo blower, and a 2990wx threadripper for the cpu

now the point is that i'd like to upgrade my sistem to 2x3080 rtx, but at the moment there are no blower edition, except for the 3090 by gigabyte, but wont take that into consideration, at least at the moment

my idea was to put instead of 2 blowers, 2 opened air cards, like the gigabyte eagle oc or similar; so knowing that each card will occupy 2.7 slot, will be possible to have 2 cards close to each other, and not have too much heat inside the case? which is a 750d by corsair.

thank you

It will be hot. A lot hotter than the 2080ti blower cards. Especially if the top card has very little gap between the two. You would be better off watercooling them.

Depends on your motherboard and if you have a fan on the side blowing air at them.

thanks man, yes for sure will be way hotter. i have 2x140mm fan on the side of the cards, one below and the aio nzxt x73 radiator above
 
What renderer are you using? Have you considered a single 3090? I use octane render and unreal engine.

I previously had a 2080ti and a 1080ti

Or as vark mentioned. Definitely water-cooling them would be a way forward.

im using fstorm for gpu. yes the second option but way more expensive would be a 2x3090 blower by gigabyte. watercooling dont even know how to do it man and dont know anyone can do it for me

im doing archvzi rendering so i need at least 16k cuda cores to feel a brutal difference. since now i have roughly 8k
 
You'll need 6 slots total, and probably the toughest part of that will be finding a motherboard that ideally does x16 on 2 PCI-e slots with that distance apart from each other, most of the issues with dual GPUs the reviewers have had is finding appropriate motherboards. That might not be as much of a problem for you since you can't do SLI so you don't have to worry about the bridge. But because many of these coolers are like 2.5 slot rather than a full 3, it means more space between the cards than if they were say 2x2 slot right next to each other. As long as your case has good airflow with some decent fans across the front panel you should be OK.
 
thanks guys for replying. motherboard is a gigabyte designare ex...i have 5 pcie slots. actually i have quite a bit of space between the 2 cards and each card occupy 2 slots. something interesting i've found out, maybe could be interesting for you also guys, is that evga is the only one manufacture to produce for the xc3 series, for both 3080 and 3090 , 2.2 slots wide cards with 3 fans. heres the link so probably i could go with them
