Ooof, I clearly didn't have email reply notification on. Thanks for all the great feedback!
I decided I'd give the Ninja a try first, with a Silverstone fan with a fan controller. See what CFM works for me best. If I don't like the Ninja, I can always return it and try one of the others, eh? Everywhere is pretty nice with their RMA policies. If the Ninja doesn't work I think I'll try the SI or XP 120 next. I've ruled out the 012 cause I measured dimensions on it and it's just waaaay too big for my motherboard. I'd have huge issues fitting in memory for dual channel mode.
And newegg does have the Ninja - do a search for SCNJ and it'll pop right up for ya.

Ah, and somewhat related, I'm going for the VF-900-Cu for my 7900GT. I have a VF-700-Cu on my 6800GT right now and it's great, and the 900 is supposed to be MUCH better. Thermaltake BGA copper ramsinks instead of the junky Zalman aluminum ones.
Thanks again everyone!
