Max is like 3-5 degrees more on your top card. Your bottom card will be always hovering around 60-65 degrees. Even at 80 degrees no damage are made to your cards. Your computer will shut off before any damage will be made. If that the case, then look into another case. Or grab a diff. model 670 with a better cooler and then put the new one on the top.
Like I said to iARDAs, 75 Celsius is nothing for these cards. They have a maximum operating temperature of 97 Celsius. Granted, it is kind of scary to think about them getting that hot, but 75-80 is no reason to say someone should go grab a different model 670 or buy a completely different case.
Also be careful about assuming and relying on your computer to shutdown if the card starts to overheat, I've killed a 570 thinking that.

Also my current 670 hits 1215mhz.
I actually dont have a front fan.
2 bottom fans that as intake
3 top fans as intake
1 rear fan as an exhaust tahts my setup.
To be honest in BF3 i usually sit around 72 max but in some ther games i saw my GPU hitting 75 degrees. Also be warned that my room is HOT. Nothinc much I can do about it. The ambient temperature is not the most ideal.
My cards boost to 1290MHz. The top card does run about 10 degrees hotter than the bottom card under full load, but even so, because of the fan profile the hottest it gets is 77-78 Celsius.
EDIT: For reference, ambient is around 28 Celsius. (Yea I know pretty hot, but with my main rig going and the folder cranking away, it gets hot fast)Edited by PCModderMike - 10/1/12 at 4:27pm
