Default Dual screens and higher temps

Anyone with dual screens noticing higher temperatures? There was a review (forget which site) that showed the GPU was idling at 90C when two displays were running. NVIDIA's official response was that it would be fixed by driver updates. Anyone notice this problem? Some reviewers have not reported seeing this and I just wanted to know if it was still an issue. And also if it is fixed is there still a rise in temperature when using dual screens.

They released a new bios to fix it, but it didn't really do much. With two monitors installed the idle is still too high. From all accounts the idle is still in the 70's to 80's, which is absurd. In contrast my 480's with a single monitor idle at 44 and 41 respectively.

Yeah that is a little ridiculous. I have a 5870 and it gets a lot warmer with dual monitors too though not by as much. The only fix I found is to use your second screen on a different video card. Might work with using 480s in SLI and dual screens but then if you want three screens you are out of luck once again.

I'm running dual monitors with a 480 and my case is a lancool pc-k62. My card idles in the upper 70's lower 80's. Seems to my like nvidia is throthling up the frequencies too much for dual monitors.. they might be able to throtle clocks down some with drivers resulting in a lower temp at idleing hopefully... wishful thinking. It's so much louder then my 8800 gtx.

I'm running SLI GTX 480s on dual monitors, and my first card idles at 50-55C and my second card idles at 35-40C. I have my fan at 80% though.

Man..I cant inmagine having my fan at 80 percent all the time.. it's so annoying, although I'm coming from years of watercooling so I have been spoiled. Dont have the money yet to go watercool this round.

Hey JasonPC, it was legitreviews in the original review as well as bios update tests for the dual monitor issue.

Thumbs down Re: Dual screens and higher temps

I can't believe they still haven't fixed this issue, I first noticed it with the GTX 280 almost two years ago. Whenever two displays are connected and enabled, the card stays at full 3D clocks all the time, hence the high temps...

I can't understand the reasoning behind it, because even with the clocks forced down to 2D speed using RivaTuner any recent card has more than enough power to run Aero/video acceleration on two high-res displays without any hiccups.

the 480's dont run at full throttle... mines clocks down about halfway with the core clock running at just above 400 mhz. But with 1 monitor it runs at under 100 hence the thermal difference. Pherhaps they'll find was to further lower the clocks when in dual monitor mode. Overall I'm real pleased with the performance of my single 480.. but it's not for the faint of heart... seeing your chip running in the mid 90's is a scary sight. Plus, to me, given I've been spoiled with watercooling, it sounds real loud. To anybody considering getting one of these beasts, if you can go watercooled, by all means do it. It's the only way I can recommend these cards.
