GTX 680 - Triple monitor, GPU temps?

I just plugged a third monitor into my 680 today and noticed that temperatures have done up sharply as a result. I know the card has to run the core and memory at higher-than-idle frequencies and voltages to power this many displays but I am curious what temperatures others are seeing. At idle with a 200mm side fan I'm seeing 58-59C. I'm not sure what load temperatures are but the 680's fan definitely spins up enough for me to hear it.

What about you?
 
It is the nature of 3-head. With an air hsf I was getting similar idle temps on my 6970 @5300*1050. Lots of pixels mean much higher temps even at idle.
 
I know that's the nature of 3x1. I just want to see what others are reporting so that I get some idea if I need to improve the airflow in my case. I just disabled the third monitor and within 2 minutes temperatures have already dropped to 50C and they're continuing to fall. If I remember correctly 2x1 idle temps for me were about 42-45C. EDIT/UPDATE: Yup, 42C at idle with two monitors.

hum, its 25c/ 77f in my room and my gpu is idle as i write this @ 34c with 3 24" screens on. fan speed is on auto @ 42%.
could be my case . have you up'ed the clocks on it ?

sorry for the small pic, cant figure out how to make it bigger showing the full desktop. here are the temps

Interesting. You have a core frequency of 324MHz with three screens on? My won't fall below 549MHz (v301.24 beta drivers) and the RAM stays at 3105MHz. Your temperatures and clocks are highly similar to what I would get with 1 or 2 monitors. I'll try v301.10 as soon as I download them. I played with OC'ing a little bit to see if it really got me anything (5760x1200 is satisfying enough with OC'ing) but I am at stock clocks.

When I'm using two monitors and I let the card manage fan speed (not eVGA Precision X) I get 42C with a fan speed in the medium/high 30's.

OK, that's something I can work with :). I'm using the v301.24b drivers for CUDA debugging support but I won't need that feature for a while so back to v301.10...might need a reboot in a minute or two here...
 
No dice. v301.10 and I'm still getting 549/3105 clocks. How are you connecting the monitors? DVI+DVI+DP? Or DVI+DVI+HDMI? EDIT: I can barely make it out in the image but you're using HDMI. I wonder if that has to do something about it. I'll have to borrow an HDMI cable from the living room...
 
Cool beans, I'm on to something here. With DVI+DP my clocks are still 549/3051, with DVI+DVI I hit 324/324. Looks like the use of DisplayPort might be the culprit. I wonder why...

Anyway, time to go digging for an HDMI cable.
 
I've got adaptive as well, but that's only for 3D applications. In any event I completely reset all settings to default anyway -- no change. I'm waiting for my wife to be done with the TV before stealing the HDMI cable.
 
What's so funny? :p

Just out of curiosity do you have the ability to use the DisplayPort connection for a minute to see if your card clocks up? I'm almost sure it will...if this works on my end I'll probably order this HDMI to DVI cable. $7 isn't too bad considering...

Alright, thanks anyway on that. I'll report back, again, when my wife will let me shut down the TV for a little bit :p.
 
The use of DisplayPort locks the card into a 549/3105 clocks. As soon as I switched over to HDMI my clocks are 324/324 again with a core voltage of 0.987V. Temps are hovering at 39C (room's a little cooler now) and a 44% fan speed. Thanks both of you for helping out!
 
good info here.
use of displayport in surround setup raises clock to 549/3105 and temps with it.
 
Apparently. nVidia needs to document that one. Without really knowing anything about the hardware associated with DisplayPort it's hard to tell if this is a driver issue or if this is just how it has to be. In any event DVI+DVI+HDMI is going to result in lower 2D clocks/temps.
 
Maybe eVGA will be able to help nVidia get to the bottom of it, awesome. At the very least it'll keep a few people's PCs cooler I hope.
