3x Blower-style cards

[cisto1999]

Is there a major difference in installing 3x blower-style cooled GPUs directly beside each other with no free slot between them or would be a solution with 1 slot free space between each card much more better for temps and therefore for performance?

The reason i am asking is case-purchase - do i need a 8-pci-slot case or will 7 be enough?

Well a blower style cooler would be better than open air but your gpu temps are going to rise vs that it has room to breath, how much thats something you might want to look up online.

I don't know much about that, but 2 gpus is really the limit for gaming if thats what you want to do

space between all three is ideal. Your temps will be higher from having them all side by side. Depends on the cards too and how hot they get. But if I were personally going to make that build I would use an EATX case. But if youre going to do this for just gaming then  you wont see any gains from a 3rd gpu. and you will see minimal gains in most games from the second gpu as sli/crossfire support for the past two years has been very poor. 

 

Even then your mobo may not support full 16x speeds in every pcie slot with then all occupied.

You would definitley see better temps with some space between each card. Still though, if you are going triple SLI/Crossfire, i highly recommend a custom water loop if you have the cash for it. It'll look amazing, and keep everything nicely cool and quiet.

It is not for gaming but for rendering.

I would prob go for the blower style since they exhaust the heat out the back instead of blowing air around the case (need a good airflow case to remove that air) What render are you using?
