is there not another slot lower down on the motherboard?

I would personally cut a hole in the case and turn the psu upside down (to reduce heat making sure there is feat raising the case off the floor) then move the cards further apart on another slot if available (you can buy longer crossfire cables) but apart from that you could always sell your motherboard on ebay and buy a different model.. but that might be a bit far fetched!

p.s buy some cable ties as i think you could improve your temps by atleast 2 degrees!
Well if there was another PCIE slot available I would have already moved it there.

Turning the PSU upside down and cutting a hole wouldn't do anything really. It exhausts out of the case, it isn't blowing hot air on the card.

And cables aren't the issue here. Like I said airflow isn't an issue, I have 2x120mm fans on medium (high shows no decrease in temps, while low shows maybe 1C increase over medium) blowing directly at the two cards. The cables aren't in front of the card impeding the airflow, but rather bellow them where nothing is going on. Even taking off the side of the case does nothing to lower the temps. The problem is GPU1 is so close to GPU2 it has a hard time drawing air in through the blower.

Lol the OP in that link provided has 2 580s for a 19" monitor.

On topic, I think you should just go for it, the performance may not be great but they aren't expensive if they really suck. Or as previously mentioned just deal till you can afford a WC loop.

looks like and IDE ribbon cable, and that to me screams a big fat NO!

I would highly suggest getting a different cooler for it instead.
Look to see if anyone would be interested in selling a dual-slot cooler that would fit your card, like the MSI Lightning for instance.

Perhaps you could aim a fan at the back of the top card for better cooling. That dropped temps by about 5c on mine. (with the backplate off it reduces it even more)

An aftermarket cooler would easily fix the problem, but I'd rather not shell out ~$30-$50+. It's not THAT big of a deal IMO.

I do intend to arrange a 120mm fan pointing at it's backplate. That should help a bit since the backplate is metal and conducts heat fairly well. Not to mention I have a lot of exhaust to take care of that heat.
I also haven't been able to replace the stock TIM yet as I'm not at home currently.

I think I will wait and work on those mods first before I buy the extender.
