It will most certainly keep that thing cool. This could quite possibly be the best air cooled setup around. I had 80mm Tornado on an SLK-800U and an AX-7 in the past and it cooled extremly well. Of course, like you said, it will be loud. Honestly, while it cools well, IMO it's not worth the noise. I'm not very noise sensitve, and I kinda l like a little hum from my box, but you could hear the Tornado across the house. As far as fan controllers go, if you're going to "bridle" the Tornado, why not just get a quieter fan to begin with. That's what I ended up doing.
