Older games only use 1 card & not sli hence only 1 card is used = only 1 card gets hotter.

even using sli fsaa 8x mode?

not just regular fsaa the sli aa mode

Can you name the games that produce this issue ? so we can find out if SLI is running or not.
also what are exactly your temps in both GPUs ??

ok in afr mode in anarchy online gpu1 is 63 and put 2 is 64.

in sli fsaa 8x mode gpu 1 is at 70 and gpu 2 is at 59

Still seems like the second card is getting hotter, just not asmuch.
Does the card perform better using that mode over a single card?

in ao i notice some performance yeah but whats wierd is that 2nd card is at idle temps, at 1680x1050, 8x sli fsaa, 16x ansio it should warm up at least a bit. especially considering how long i play this game.

like i said once i go to afr mode, they both get in the 60's within one degree of each other, which from what i understand is normal behavior. im wondering if maybe they broke sli fsaa in this latest beta is all somehow

Well in that case i think its normal since in SLIAA mode one card does the rendering + 4xAA & the other does the other 4xAA sampling which then combined together to produce 8xAA (or 16x by 8x + 8x) . so the first card is actually doing more work that the second i believe.
i didnt check my temps on SLIAA , but thats what i believe is the reason.
