Change 6950 auto-fan speed?

[KNiVES]

I'm happy with the current temperatures on my 6950s but I feel they could be even lower. The fan generates almost no audible noise so I feel I can get them to be a little more active and keep temperatures even lower. It's a crossfire setup, so keeping them cool is essential.

I know there's manual fan control, but I don't really want to leave them both at the same speed all the time. It doesn't make sense to have them at 80% speed on desktop for example. I remember on my old system with a 4850 that I could access and change the fan speed parameters when the card reaches certain temperatures (it was a config/html file), is this still possible on modern hardware?

You could set up a manual profile with MSI afterburner. You can also modify the cards BIOS and change fan curves in there if you have a dual BIOS switch (and it works).

What 6950 is it? My 6950 made a lot of noise when it got above 25% duty cycle so I'd imagine it must be a different one.

This seems to be a bit hit & miss, I've modded both my 6950s with unlocked shaders and upped the core voltage, but messing with anything on the fan profiles has always resulted in BSODs.

So as suggested previously, Afterburner allows you to configure your fan profiles very well.

Thanks for the responses guys. They're Sapphire Toxics
I'll try the Afterburner tool. As it's made by MSI, does it also work on non-MSI cards?

Yep! Both my cards are Asus- works fine.

I've just downloaded and set it up, it works like a charm I've decreased the temperature ranges needed to speed the fans up by 10 degrees and now the cards are much cooler and don't even make that much extra noise.

Cheers!

edit: I'm not sure how to get it to apply to both cards though, it seems that the settings only apply to the first GPU according to the graphs, any help?
