Sli on mATX

post #1 of 19
Thread Starter 
Hey guess, not sure since im going to be using a mid tower case but a mATX if its okay to SLI. I am using a Haf 912, with 2 addition fans along with the 2 stock, a Gene V mATX ASUS MB, CM 212 + and I am planning on getting a second 680 GTX. Currently I have the 680 GTX SC + wit ha a backplate, now i heard temps get REALLY high with mATX ( I had crossfire 6870s on a mATX but temps were okay however I had fan's always quite high) is this true? What aftermarket 680 should I get, and what position should it be in, Top or Bot?

make sure the bottom GPU doesn't have a backplate, else it'll starve the top one.

Best to go with both reference in order to eject all the hot air out. If you don't mind the noise.
Shhh!

SLI and crossfire make for warm/hot temps even mid sized ATX. it's just with 2 cards you can' really fit an aftermarket VGA cooler and add to that the heat from the bottom card rises because heat naturally rises and the top GPU sucks in that heat.
This is one reason why intake fans are more important on/in a case than exhaust fans.

I dont get how a backplate is bad?

top card backplate = no problem

bottom card backplate = even more limited space for the top card to intake air. (the bottom card backplate almost covers the top cards intake)

this is in a a 4 slot m-atx sli configuration.

top but make sure its only a dual slot card or else you will not be able to sli them. the top card usually gets hotter since it has less airflow going to it because of the restriction of the card below it

and the hot air generated from the bottom rising up and getting sucked in to the top card's fan.
