GPU Fan control ? (Nvidia)

[alamic05]

I was wondering if there is any program or modification to allow setting the GPU Fan speed ? The card (Nvidia GT 440 ) many times reaches 70-80 degrees C under full load.

so far this program help me, to put down some degrees

so will this work on a gtx570 i see that you have a gtx 580 did you use it on that card ?

80°C is no problem for GPUs!

What you can do is:
- extract the GPU BIOS
- change the fan-curve (with nibitor)
- flash the BIOS back to the card

Sorry for bumping old topic, but I can't send private messages.
Dschijn, I can't find any info on that link about the fan curves, can you please help me with editing fan curves?

Thanks

 

[Dschijn]

Sure. I see it in the 5th picture
Well it's more a fan ramp, than a curve.

Thanks for the reply.
Yes I've seen that picture too, but in NiBiToR I can change only min and max fan speed.
It is not possible to make something like that? -

I havn't done it, because it will void the guarantee. You can try it with some values… Min and max should be related to temperature targets of the card.

Yes, but problem is that when I stress GPU fan speed doesn't change, because of the OS.
For example if I have 50% fan speed on idle, when I play game I'll have 50% again. In Windows I use Afterburner tool and I can adjust fan curves, so fan speed goes up when GPU temperature goes high.
I need at least 70% fan speed when GPU is loaded, if I edit min speed to 70, it will be always on 70%. I don't need that and I don't understand why do I have only this problem.
I hope you'll understand me, I'm speaking English not too well.

speak german?

You need to set min and max value for fan speed. Like 50% and 100%. If the temperature is increasing the fan speed should also increase itself.
