your 2nd gpu intake fan is bringing in hot air from the 1st gpu. You either put a giant fan or remove your chassis

Yes ! Got your point !

But when I look at things like this on Google :

There's basically no air or spacing. How come ? They run at 100C+ ?

In my case, right now, there's about 4 slots left between the 2 cards. It's not crazy space, but it's more space than what I see on most pictures.

That's why I'm asking myself if that's the right card for a chassis, and/or if I should use horizontal/turbine fans like on the "reference" cards who will rear-extract the heat.

Thanks !
