570 too hot?

[liscoe]

Hi,

Bit concerned about my gtx 570 temps- from comments and reviews read online the card should idle at about 35-40 degrees C. Mine however seems to idle at over 60 and I can't see a reason for this.

I have the stock cooler on the card and it is set to automatic, currently running at 48% 1380RPM. Even when running the fan at a top (noisy) speed of 85% 3930 RPM the temperature only comes down to 44 degrees. When gaming temps hit 85 degrees!

My pc has been on less than an hour this morning, I have two 120 fans in the front of the case and one in the back so there should be decent airflow. My motherboard temp is 32 degrees and my cpu also 32 (noctua D14) so I don't understand why the graphics card should run so hot! I was hoping to overclock the card but concerned already that things are running so warm on stock speeds...

Ah yes just been playing with settings and I do have two screens attached- disabling one of them drops temps dramatically down to about 45 degrees. Noticed though that my card only drops down to 405MHz instead of 50MHz as it should. Strange, time for more investigating...

Are you running two screens? that will effect idle temps dramatically.

Also my card hits 85c on full load, Crysis etc.

*******************************************

The 500 series has 3 modes, on the GTX570 it is, idle (51mhz), 2d (405mhz), and 3d (732mhz reff), make sure in the 'Manage 3D settings' in the Nvidia control panel that on the 'Global Settings' tab you have power management set to adaptive, if it's already set to that click and apply it again, also what program are you using to monitor the core clock?, I'm using MSI Afterburner and it does take a few seconds to down clock sometimes, also running two screens off one card may stop the card running in idle mode (51mhz) and might just down clock to 2d mode (405mhz) instead, try disabling your secondary screen and see if that effects it.

Thanks for all your help- when I disabled the second screen and rebooted the card now runs at idle and temp is 38 degrees which is fine.

Bit annoying about running at full speed just to power the second monitor though- I'll just have to enable/disable as required...

What resolutions are the two monitors? I've read that if the second screen is the same resolution as the first, the card will still down-clock to 2D (51MHz) mode.

I've got the GTX460 1GB and with two 1920x1200 screens it clocks down to 51MHz. I'd assume the same with the GTX570?

And just to think people have a pop at AMD for the same issue.

Becareful about running the cards clockrate to low otherwise you will get screen flicker.

sorry to butt in, but I never knew about this, i wondered why my 470 was a bit warm. thanks

Not true. Modern Nvidia cards can handle dual-screen at the same low power setting as in single-screen. The condition is that both screens are the same resolution etc.

Been running dual-screen on GTX460 since it came out and it's always in 51MHz, low-voltage etc.

Buy a second card, sli them then you can have one screen per gpu. Win/win situation! (provided the rest of the system supports it lol)

I have a GTX470 with 2 monitors attached (both 1920x1080) and a third running off a cheap GT210.

My GTX470 clocks down to 51/101/135 like it should, my idle temp at this very moment is 36c

Is your graphics card settings in the NVidia control panel set to adaptive?
