Worried about GPU temp SLI

I have a second 580 coming in but the SLI cord connecter that came with the motherboard is gonna make me put the second 580 directly below the first 580, any know if this is gonna make the temps go way to high? They will both be overclocked to 830 core, 1660 shader, 2050 memory, like the single on I have right now is at, and that one runs nice and cool. My mobo is ASRock Z68 Extreme4 Gen3.

Also while where on the topic can my PSU handle it? Its in my sig.
 
Oh one more thing, do I leave the drivers installed? Will the second gpu just pick up and use the drivers or should i get rid of them, then re apply the same drivers?
 
The temps will go up, 100% sure. The question is, will they be safe? Which cannot be answered until you get the second one. And that PSU is fine.
 
Ok, I don't even think you have an option of running it any other slot, because the 3rd slot runs off another external chip. This adds PCIe lanes that SandyBridge lacks. Like my motherboard, you will probably need to use particular slots regardless of the bridge length (it will come with longer ones).

Having been there done that, you will need to watercool one or preferably 2 of the cards. You can try and run them on air, but expect above 95oC under 100% load.

Watercooling will be required here IMO although given that your cards are OC varieties, they're probably not reference design pcbs, which may prove tricky

With the new card installed, max the fans and run the Heaven Benchmark whilst monitoring GPU temps.

Then add 5- 10oC for summer if its not hot there now, and thats where you'll be.

Alrighty I'm installing the card now, the single 580 max temp sitting at 100% load is around 69-71C so I hope it doesnt rise to much.
 
Didnt run any benchmarks just played bf3 for about an hour, and the max temp was 75C for one card and 72C for the other. Tested sleeping dogs benchmark to see how it improved over a single 580, and it did pretty good.

Single 580
Average FPS 60
Max 86
Min 33
GTX 580 SLI
Average FPS 98
Max 169
Min 59

Also tried the RE5 benchmark but it failed to have any serious results, one 580 averaged 131fps, SLI averaged 153 when it should be around 270fps according to what everyone else is getting SLI.

Any other games or programs good for testing how much fps scaled?

Ok just did the Heaven dx11 bench, just posting this stuff so you guys can tell me if I'm getting the right results or if somethings messed up and they should be higher.

Settings where maxed out including Tess, AA, AF ect at 1920x1080

Single gtx 580 results
Average FPS 36
Min 10
Max 91
Score 918
gtx 580 SLI results
Average fps 70
Min 27
Max 173
Score 1781

Yeah well that scaled around 100% so its fine. Suprised at temps.

I'm using MSi afterburner and it keeps the fans at whatever the gpu temp is, so it rises to about 70c then stalls out, after hours it will hit maybe 75c to 77c but I've never seen it get higher.

probably helps that my rooms always pretty cold, and my case is giant with a million fans lol.
