Hi everyone, noob here, if i was to get a second hd 7970, how would i cool it? For example woudnt the top card heat up the bottom card? which would overheat the card too much. Or is a normal fan going to do the trick?

And also can i buy a different card like a sappire instead of powercolor of the hd 7970?

Thanks in Advance

My specs are
hd 7970
core i5 4670k
msi z87 g41

make sure your psu can handle 2 gpus

i think heat isnt a big issue. as long as they don't burn its fine i guess. like 70-80 C would be max,
depending on which model. totaly fine.

using 2 hd 7970 from 2 brands isnt a problem. only the clock speed would be automaticly adjusted to the same level as the slower one. so no issue.

Thank you!

I just checked my psu i have a corsair tx 750 v2, but i noticed it has only has one pci e connector but alot of 4 pin connectors laying around. I hope i will be using that to connect my hd 7970.

Thanks again!

Hi - double check your connectors - the TX750 V2 has 4 pcie connectors, and it's
not modular, so they gotta be there. And they are the 6+2 (8) pin variety.
You will need all 4 to CF 2 - 7970's.

Hi, thanks again, incredibly helpful people in tomshardware. I found it was tied up and was put it under my drive cages. Thanks again.
