Hello all.  I did a search, but did not find what I was looking for.
 
I have two GTX 570s running in SLI.  I am running the 285.62 drivers.  I want to know what the max operating temperatures are for GTX 570s, please.  I am a little concerned my cards may be running too hot, although I am not getting any artifacts, or graphical anomalies.
 
My current operating temps (per the eVGA Precision software) are as follows:
 
Idle:
Card 1 (top card): 81 degrees Celsius
Card 2 (bottom card): 50 degrees Celsius
 
Under load (currently playing SWTOR):
Card 1 (top card): ranges from 92-98 degrees Celsius
Card 2 (bottom card): ranges from 85-89 degrees Celsius
 
My load numbers prior to the SWTOR 1.1 patch were:
Card 1 (top card): ranges from 89 degrees Celsius
Card 2 (bottom card): ranges from 85 degrees Celsius
 
I run all game settings on max.  After the recent SWTOR patch, I noticed my temperatures jump, and I now hear my GPU fans spinning up, which I never noticed before.
 
Thank you in advance for your assistance.

Max temperature is 97C.  Your temps do seem a little high.  My 570's idle around 45C and have a max of about 70C (top) and 65C (bottom).  How is the airflow in your case? Can you maybe clean up some wiring or add fans to help out?  If you have the cards next to each other in the first and third pci-e slots, try moving the bottom card down to the lower pci-e slot to space them out.  You could set up a fan profile in EVGA Precision or MSI Afterburner to increase the fan speed as the cards heat up.

I too have that case and a pair of 570's. Those 230mm fans are not that good same as the 120's that came with it. My idle temps right now are 31 bottom and 34 top card. I know that my temps might be lower because my cpu is water cooled as i dont have heat from my cpu going into the case. I have also replaced my 120's fans with cooler master 68cfm fans. I dont play SWtor so I can not tell my temps for that game, but when i play Batman Arkham City my GPU temps dont go over 62-67c.

Thanks for the detailed response.  I will look at the profiles.
 
I have seen others asking if both cards will be flashed at the same time, but I have not found a definitive answer yet.  I would like to try it though, since that extra 15% could make the difference on my heat.  I definitely don't want to burn up one of my cards.

Yeah, the auto fan setting at default is not adequate. I too run SLI GTX 570's and they usually reach 66*-74*C while gaming and I keep my fans at 60% or higher.

Ok, I just flashed my cards.  I found other posts where users have done this, so that made me feel more confident.
 
I ran the flash program and it automatically searches for each card, flashes it, then searches for the next card until the process is complete.  Once complete you can see the script say 'no other cards found', then the window closes.
 
Now that my cards are flashed, I will look at creating some profiles.

I don't.  I blow air through the fan intake, and I blow air backward through the fan exhaust ports on the cards.

Perhaps I should take them out and blow them out individually.  Good idea.

 
After awhile, dust builds up on the heatsink underneath the plastic cover and I couldn't blow it out with air.  You can take off the screws around the side of the card (very small, don't lose 'em!) and the two in the middle of the backplate and lift off the plastic.  Link for pics, go to pic #9, 11, 12, 13 for plastic shroud removal.  The heatsink and fan will stay in place and you can clean out the dust with a q-tip and some air.  For my fan profile at 1.1V I have 70% @ 60C and 80% @ 70C for reference.

Nice picture process.  Thanks for those!

I took both my cards out today and took the air flow shielding off so I could inspect each card, and blow them out.  I have attached pictures of what I found, which wasn't anything; exactly what I expected to find.
 
Cards have been in my rig for almost a year and a half:
 
Card 1 before cleaning (nothing significant found under the air covers): 

 
Card 2 before cleaning (nothing significant found under the air covers):

 
Card layout in case:

 
I'll continue to watch my temps, but think I have covered all the bases I can for now with heat control.
 
Thanks again for everyone's help and feedback.

I'm going to have to go home and try the suggestion of physX like you did above.
 
I have a very similar setup to yours and am getting same temps and I've tried everything as far as airflow goes.  Never thought about moving physX from the top card to the bottom.  Can't wait to see the results!

I always attach my monitor to the top card and set the bottom 570 to PhysX.
 
Idle:34-36c
Fan speed: 60% 
 
Load (BF3 on Ultra settings): 70c max.
Fan speed: 70%

Cool.  Keep us posted and let us know if it helped you.

 
Unfortunately still running at same temps..it was a thought tho!  I'm going to see if I can get the fans to 100% by flashing the cards.

I noticed you said you had lots of fans, and flow.  I'd double check the filters that are on the case too.  Since that will cause problems, and  if any of the fans are installed backwards.  Too much flow, or improperly balanced flow is just as bad as none.    But clogged filters will be the death of ya.  My 560TiSC can run hot if I've been running it for 10hrs straight and hit 80C with the room being 25C, but I'm using 2 fans to cool the entire case.  A single 600rpm fan in the front and a 900-1800rpm fan tied to the cpu line.  That's with 6 drives, and a 750w psu inside as well. 
 
My setup is much like yours with the psu bottom drawing.  Though, I'm using a coolmaster 430.

've got those temps on BF3:

with 22-23° room...
but i had to make a fan profile like this:
 

 
Btw...why you don't use pci express 2 and 4??? you could have a lot better temps...

I just wanted to throw something in here. The Azza Hurrican is a nice case, but you may want to look into upgrading a few of the fans. Front ones for starters and replace the 2 top exhaust fans either with better 230mm's or a few 120-140mm fans. The fans in that case are VERY horrible at moving air. I used the case myself before my HAF and upgraded all but the two side 230mm fans.
