Sapphire "Intelligent Fan Control III" overrides any software that tries to controls the fansAnd it's not possible to change the IFC3 fan curve.
Loads of Sapphire owners complaining about it. I should have done a bit more research given that I got shot of my Sapphire 480 because of loud fans!!
Feel like such an idiot!

Well that sucks, just did some reading about it, why the **** would Sapphire do this?
Glad i ended up with the PowerColor now as i coudnt find any Sapphire 56's at the time anyway.
I usually go with Sapphire too.
