New 2nd moniter overheating my GPU?

post #1 of 3
Thread Starter 
Hey, im a little new to this site, so i do apologize if i ever sound stupid.

Basically i got myself a second monitor and now have dual screens. Ive also got two GTX 470's in SLI, have had them for ages so yea i know dont judge me Anyways I've noticed however after i finish playing any game, one of my Graphics cards (the one with my two monitors plugged into it) wont cool down like it use to, while the other one does fine. Normally they sit ~40 degrees Celsius. And go any where up to 80 degrees when playing a game. My problem Graphics card stays at ~70 even though im no longer playing anything.

Its only started happening since using two screens (note that only my primary screen is used for gaming, the other is just sits desktop.)

Any idea why this is happening?

Cheers

Back when Fermi released many people have run into this issue and Nvidia said it's supposed to be normal. It makes sense when connecting to a 2nd monitor the GPU clock speed and RAM will crank up higher to process the information sending to a 2nd device.
I heard the new BIOS and driver can fix this issue, did you download the latest driver for your card? Rather than that at 80C when playing game is totally normal, all you have to do is just adjusting your fan speed accordingly.

With the second monitor, your primary GPU is no longer downclocking when idle. That's why it's idling in the 70s instead of the 40s. NVIDIA claims this is intended, but as the poster above said, newer drivers are allowing dual monitor downclocking in certain circumstances. Unfortunately it's not guaranteed, because officially they should not be downclocking.

I have dual monitors and my 580 downclocks, but it's a bit buggy. After a fresh reboot, it downclocks just fine until I play a game that is "new" to my 580. After exiting the game, the card will not downclock again until I reboot. After I reboot, the card downclocks just fine again, and downclocks just fine after I play that same game that is no longer "new" to my card. Wierd, huh?

Are your monitors exactly the same? If not, your card will never downclock. If they are identical, in the future you may get lucky and drivers or firmware will be released that allows your card to downclock again.
