The card shouldn't be running that hot at idle. What kind of case have you got?
I've got a Rosewill Destroyer, I believe. 1 120mm in the front, 2 top for exhaust, 1 in the back.
My case itself usually is pretty cool. My cpu idles are low. 30ish, and under load maybe 50-55 tops.
Like I mentioned, my gts card ran super cold. In the mornings when I'd first wake it up, it'd be at like 28c, but this is always around 55. The lowest I saw it was 45c idling after a cold night the other night.
This GPU takes 2 rails instead of one, so maybe it's just putting more pressure on my system? I have a corsair GS600 to power it all. I know it's barely enough, but maybe that has something to do with it?
I should add that my fan profile through Afterburner is custom. I have it set to essentially 1v1. 50c = 50% fan speed.
Even if I ramp up my fan speed to 90% while doing no gaming, just idling, it only goes down to maybe 46ish. So, being that it's idling around 50-55, my fan speed is pretty high. I don't like that too much either.
what's the card idling at in MHz? nothing is wrong with your card... my PC sits in front of a window so it keeps my components cool. are you using CCC to check your temps ?
again there is nothing wrong with your cards temps... under full load my card hit 70-72*C... which is far under the 95*C worry point... you could just have a different fan profile then myself also.
I am at stock for stats on the card, and I use MSI Afterburner. 900mhz core and 1050 mem clock which is how it came out of the box.
The double D edition is supposed to be cooler than the other 6870's due to it's double fan design and copper piping. So far, I have noticed that it barely has an increase in temperature, even under a full load, but those idles just feel too high. Maybe I am spoiled with 28c idles from the GTS 450 though.
I played arma 2 for nearly 6 hours straight, and when I tabbed out near the end, I was only at 56c. Something just doesn't seem right. I actually just changed up my fan profile. Before, it was 1-1. Meaning @30c, my fan was at 30%. THen 60c=60% etc. Now, it's -10. So, an idle of 50c, is 40% fan speed, up to 60c. Then I ramp it to 1-1.
it sounds like your card isn't throttling itself when it's idle. it's been awhile since i've used afterburner... using CCC with the 6870 is a set it and forget it since it doesn't OC very well...
and yeah, the GTS450 wont idle like the 6870, and the DD isn't anything like the twinfrozr type coolers so i take it with a grain of salt, yeah it's two fans but they spin slower then 1 (makes it some what quieter) this card runs slightly cooler then the old reference 5770 i had before it.
