Help with 570's

Alright folks,

Just been having a play around OC'ing my 570's to squeeze that little bit more out of them. Now, I'm currently using EVGA Precision X as the tool for all that is needed. My 570's are different brands though, because I was an impatient barsteward and just bought the first one I saw. My first 570 (top slot) is a Gainward Phantom and my second (bottom slot) is an EVGA one. I've just been testing it out and all seams well except for the temps. My Gainward maxes at 71c but my EVGA goes up to 87c. I understand that the Gainward one has a better cooler but I was always under the impression that the main card runs the hottest? The Gainward card exhausts from the back and not the bottom so I don't think it's heating the EVGA card up. I think these cards are safe up to 97c?

Here's a couple of screenshots under idle (stock clock speeds)

As you can see the EVGA one is running quite hot at idle, but it appears to always be under load? Why is this? :confused:

Appreciated any help lads :)
 
Higher temperatures are expected with SLI. I too run 2 570s. One's a reference Asus, the other is a EVGA HD. Mine are a slot apart with both fans clearly exposed. Top, Asus card hits 80c whereas the bottom one maxes around 65-67. Ideally, it's best to keep them below 80-85c.

A lot of people use Antec Spot Cool fans to direct airflow into their two cards:

That's an idea. Cleaning never hurts too. You can take the shroud off the EVGA card to clean it.

You could also add some fans into a side panel (If that's possible)

Hi,

we do also allow to remove the cooler so you can change the thermal paste, if you use high end thermal paste this can lower the temps too. With the precision Tool you can also set up a custom fancourve, if you raise the fan speed earlier then the auto settings you can mostly run it cooler with the same final speed. Generally our card is inspected up to 105 degree. Normall working temps are arround 80s so yours is at the higher end but still ok for this chipset.
 
I can always give that a try cheers mate. I just don't udnerstand why the second card is under load even at idle? Is it not switching back to 2D mode from 3D?
 
Hi,

if the card will not downclock anymore to 2D mode it do sound like a driver issue or something is running in the backround, have you checked this? In a case like this I would suggest to clean out all driver and tools that do have access to the card with a tool like driver fusion and download/install only the latest ones.
Have you already tried to test the second card alone in your system if it will act similar?
 
After a bit of research it's because I'm using 2 monitors. In SLi the 2nd card is always under load because of this and the first card is loading 405mhz because that monitor is 120hz. If I drop the hz to 60 the card then idles at 50mhz. Thanks for the help though guys, all makes sense now.
 
Thanks for the update. Yes, I did forget to mention if you have screens connected to the second one this could also be the reason. Nice to hear everything is running like it should now :)
