Hi all, please talk me out of something stupid.

After some adventures with eGPUs, I've ended up owning four 1080 Ti cards (all EVGA multi-fan, non-blower designs): 2x GTX 1080 Ti SC2, 1x GTX 1080 Ti SC Black, and 1x GTX 1080 Ti FTW3.

I'd like to see what happens if I put them all in a case with a modest Cascade Lake i9, or a Threadripper CPU. It would be primarily for GPU rendering, so the CPU isn't the star.

I've been looking at the Cerberus X case, with an ATX or EATX motherboard, a Corsair 1600W ATX PSU and wondering what happens if I just load the case with exhaust fans all around.

Will that allow the 4x GPUs to perform at all? I don't mind a little thermal throttling, there's four of them, and as I said I already own them, so that's a sunk cost.

I suspect it's a bad idea, although I'm hoping maybe not. Any thoughts appreciated.

I think this sounds like a *great* idea - pushing boundaries is what it's all about!

Its a bad idea all the cards will end up thermal throttling by sucking in each others hot air. But theres no reason not to try it if you feel like it, just dont expect it to work well if at all.

Maybe you can try it first with an open bench?
I bet, even so, the first 3 cards will still have thermal throttling.
But if you have nothing else to do, this could be a 'fun' project.
Pushing the Corsair 1600W to its limit could be a huge part of the 'fun'.
