I have 2 ati visiontek hd 3870's in crossfire
I was originally using the Fixed fan speed duty cycle for both video cards using rivatuner, the main card always runs 10deg. C hotter than the other 1 .
If I run the cards by themselves they idle at 72 deg. celcius and the fan are running but at a very low speed
So I have the main card fan at a fixed duty cycle of 65% and will keep the main card at mid 40's deg. C at idle.
And I have the Secondary card fan at 55%fan duty cycle and has it at usually around 38deg. C at idle>
But when i'm playing Cod4 or ut3 for a good amount of time the cards will still over heat and reach 80+ deg. C and they started to freak out and the VPU recovery kicked in....but it still locked up the video.
I did a hard reboot and lost the resolution setting (no biggy) ,but noticed that the cards where over 80deg. celcius, but then quikly cooled down because I wasnt playing any games by then, and i know that the fix fan duty cycle settings werent enough to keep up with the heavy demand the cards have, while playing games.
So... I tried to create a fan profile with riva-tuner ...i found a tutorial on how to do it ...so I managed to do it for the main card and it seemed to work.
I created my profile to work like this :
Fan speed 100% > 85 deg C.
90% > 80
85% > 75
80% > 70
75% > 65
70% > 60
65% > 55
60% > 50
55% > 45
50% > 40
So this was my fist time trying this and i figured I could always go back and tweak the settings and temps if that profile is too loud.
But i noticed it wasnt working for the second card as it was now running hotter than the main card.....so i tried to set up a profile for the second card ,but it kept saying "the profile is corrupt or missing ,would you like to edit profile"(yes/no) and it keeps popping up with that error message no matter if I click yes or no.
I am able to control both cards using the "fixed " fan setting control ,but i would like to have something more automated for both cards.
Either i'm doing something wrong, or rivatuner isnt capable of controlling 2 card in crossfire.
I have already updated the ati drivers to 7.12...they were just released....no change at all by themselves.
If I dont use riveatuner they instantly overheat
Tell me what you guys think
