Those temps aren't too bad, maybe a little warm, they can run safely in the mid 80's Celsius with no problems. Have you tried creating a fan profile in MSI Afterburner? That will most likely lower your temps quite a bit. Nvidia default fan profiles suck and wait way too long to increase fan speed. I was getting mid 80c with my gtx 285 and was able to knock it down 10c using MSI Afterburner, and the fan was still reasonably quiet.
that is also another question I have. I read into using programs like Rivatuner to adjust fan speed. Is this adjusting case fan speed or graphics card fan speed? I am under the assumption that it is graphic fan speed being that the case fans are wired to the psu.
I also read that plugging your monitor into your second lower graphics card can also help disperse heat more evenly.
Do you guys normally hook your case fans up to your mobo to control the case fans speeds or do you just plug them in and let them go at whatever.?
Also do you have any recommendations for profile settings right now I have
30c = 30 fan speed
40c=40 fan speed
50c=50 fan speed
60c=70 fan speed
65c=90 fan speed
70c=100 fan speed
I use a fan controller for most of my case fans, and the couple that are hooked up to the mobo, I set them to 70% in bios to keep them quiet. I like the fan controller because I can do similar things to afterburner with my cpu and exhaust fans on the fly as needed. The only thing I can see that I would change is the 90 and 100 percent fan speeds at 65c and 70c. It must get awfully loud running the fan full tilt. Maybe try a lower percent and see how the thermals are. 70c is cooler than you need to be unless the fan noise doesn't bother you.
