Hello,

I have an older 8800GT with the smaller fan, I was wondering, I don't mind about the sound but what is the best fan speed settings to use in RivaTuner?

Thanks
 
Well then, that would be 100% all the time to keep all the board components as cool as possbile for long life and reliability/stability. However I think you are lying about the " I dont mind about the noise" or, you will shortly begin to "mind about the noise". :p

EVGA cards have a bios update that ramps the fan up sooner. You can establish your own "setpoints" for ramping the fan speed or you can just set it run a little faster in 2D and 100% in 3D and use the launcher. or or .... Everything is a tradeoff between noise and cooling. Some manufactures assert that the chips is rated to run 105C all the time. I personally do not buy it, it might not fail but too many people postes about screen corruption at those high temps. And it is a universal truth that electronics lasts longer (the gpu is not the only concern, there are plenty of other components on the board that are cooled by the fan) the cooler they are.

You want a number, set the fan speed so the gpu does not exceed 80C in long sessions of your favorite game.

Try these settings:
35% < 60 degrees C
40% > 60
45% > 70
50% > 80

Obviously the faster you set the fan the cooler it's gonna get, but most people have reported diminishing returns after around 60% fan speed. My card idles at 58 degrees and has gotten as hot as 84 degrees under load. By comparison, without Rivatuner I was hitting 102 degrees under load.
 
do you guys underclock your gpu @ 2D? I see no need to have high speeds for 2D apps except for playing videos/divx/avi.

I tried to underclock in ATITool but it did not work. I hope Riva Tuner allows you to underclock.

My temps are 53-58C idle, 90C in crysis,bioshock, etc after about 15min and playing 1 hr.

at the very least i would add 100% > 90 (or whatever you want your temp ceiling to be). With the settings you listed you're locking your fan to never run above 50%. not sure if these cards throttle down or not at a certain temperature, but why risk that or a lockup due to heat? i always make sure to have some sort of temp safety net when setting fan profiles in rivatuner.
 
crispy let me know if u have any luck underclocking the 8800gt I have one and was wondering how well the gt would do in that dept.

Will try it tonight and will let you know. I hope it works. 2D doesn't need much for video playback.
