Hi,
I have three cards running at 100% fan speed at the moment and the temps are 68 max. I still haven't overclocked them.
Any info greatly appreciated - thanks.

You don't really have to run them 100% all the time. Just keep temps below 80C or so. (6990's run hot... Seems like you're generally not hurting anything till you go above 90C)

Yea I have 2 x 6950's and have set fan speeds using Afterburner. One seems to run at a higher temp than the other so atm 1 runs @ 61c @ 71% fan speed and the other @ 71c @ 91% fan speed. I could lower the temps further but then you have the noise issue to contend with. I think this setup of not quite full fan speed and < 71c temp to be a happy medium. At these settings my cards arent being hammered and they can run all day like this (they could run @ even higher temps safely) w/o fear of component failure.

i'm running 12 x 6990 at the absolute edge in overclocking mode (power, temp) - they are all running at 100% 24/7 - unfortunately i have to clock down if the ambient temp is rising, but i use a script for that - a few pic: http://imgur.com/a/usqDL |

Yes, run the fans at 100%. You'll get more lifetime from the cards with lower temperatures, but the fans might wear out sooner. |

I think my card's temp is an issue. But I have no idea how to fix it. I currently only have 1 6970 and when it's mining it's at 90-92 C range. But when I stop mining, it gradually drops to low 50s. Reading this thread, it seems like 61 C and 71 C is the range 6990 should be in. 6970 is even less hash power than 6990; under that logic, should the temps be lower?
But how do I fix the issue? For Win system, people use MSI Afterburner to control the GPU fan; but what does Ubuntu (Linux) use? I looked at MSI Afterburner and it doesn't look like they have a version for Ubuntu. So I youtube and found out people use LM-SENSORS. I haven't tried setting that up; but the whole clip looks weird.
Anyways, enough of my ranting. As usual, I welcome any and every advise.

Got a need for speed? |
