First of all, a big thanks to Dogie for the setup guide.

I'm looking for the collective wisdom on the best fan replacement for the Cube. I am looking for one as quiet as I can get it while moving enough air to run in overclocked mode. Specific model recommendations would be dandy (I read earlier in the thread that someone recommended a Scythe Gentle Typhoon model), but even knowing the minimum CFM rating it needs would be very helpful.
