Hi guys , my current setup is a crossfire between two MSI r9 390x cards.
Im using corsair 600Q case, the cards sit really close to each other and the main card tends to overheat. It goes up to around 80-90C, while when I used the cards separately they never got to 80C.
In my mobo i have 3 gpu slots, I'm using the first two because the third one is blocked by part of the case frame.
I thought of getting a bigger case so that I can use the third gpu slot (to space out the cards and allow for better ventilation). My question is will this be enough? If not, what other suggestions may I try?
Thanks :)

If its the main card (top card) that is overheating then its most likely an airflow issue as you said. Easy way to see if its an issue with airflow or the cards cooler is to simply swap the cards around so the secondary one is the main one (or remove the secondary all together) and compare temps. My 290x's have 2 free slots between them and the main card runs at a max of 70C under load. It doesnt seem like you can do much else with the case in terms of airflow so i would say if it is the cards being too close together upgrade to something like a 750D :)
