Hey guys,

I have 2x 5770 cards in crossfire. The top card gets damn hot. enough where i put my finger on it and its not going to burn me but its not comfortable either.

my question is what temperature range should a 5770 run at and what temperatures are they rated to go to?

I've been trying to find a longer crossfire cable than the stock one but i can not find one for sale. The cards are practically touching.
 
Use an app like MSI Afterburner to log the temps of the cards. Anything under 90°C at full load is fine.

How is your case cooling? You need good intake and airflow to provide the cards with enough cool(er) air.

Also try setting up a custom fan profile, easily done with MSI Afterburner. The stock AMD fan profiles are quite benign. They tend to want the card to run at 100°C+ before they will really do anything about it.
 
wow, I did a little searching myself and I can't find any longer CF connectors either. Only thing i can think of is upgrade to a 5970 or water cool the cards you have.
 
If you can touch the card without burning you it's fine. Typically cards are designed to run up to a point where you would be unable to touch them they're that hot. That's simply their design (and also why they carry heat warning stickers).
