I was noticing that one of my cards gets quite a bit warmer than the other one, and was wondering if this was normal. Attached is a screenshot after a 60 second Furmark run....

I see that the fan speed is on auto.

Yes the first card does a lot more work. Also see which card you have physx on. I set to the gpu 2 to take some load off the first card.

They are right next to each other yes... Unfortunately I am on a micro board. I believe my case has fairly good airflow. I have a SickleFlow 120mm fan right next to it running 70 cfm.... ?

they're EVGA cards. they have crappy cooling. they're expected to run hot. although at that temp, don't expect ANY overclock at all.
my cards usually gets around 76 on first card and 71 on 2nd card playing crysis on hot summer days. and that's like the maximum spikes. normally they stay under 70.

Is there any "mod" I can do to decrease the temps?

I had the same problem with my GTS 250's. I had to move one of the cards to a further slot. To do so, I needed a longer SLI cable...

It makes a huge difference.

I'm curious why the first card would be doing 'a lot more work'? What work is it doing that the bottom card isn't doing, exactly?

I had always assumed that the higher temps on the top card were attributable to restricted airflow and/or the presence of a large, very hot card sitting right underneath it, with the heat rising directly into it's fan.

And I can't figure out how which card is set to do physX would matter in Furmark, when it doesn't use physX

It could be PhysX or CUDA or something to that affect that will only run on a single GPU and doesn't scale in SLI.
