Summary: This thing is SILENT! I was a bit skeptical when I bought it. I already had fans that work fine, I just wanted something quieter. This moves more than enough air, and is about as quiet as physically possible!
Summary: I needed a 120mm fan of the strong, silent type for my project. This Noctua is a stealthy little turbine. Throttled back to just seven volts it is inaudible from a foot away, yet can still move enough air to safely maintain lukewarm temps for 150 watts of cool-tubed, darkroom vented, high pressure sodium goodness. Two of these stacked in tandem would be a ventilating ninja. SCIENCE !!!
Summary: Other than their color, these fans are excellent buys. They generate vry little motor noise, all one hears is the rush of air. The leads are generous and I'd like them a bit shorter. Good warranty and company support. In all I now have and use 10 Noctua fans in 3 machines and will have 4 more in a new build.
Summary: IT'S ACTUALLY 52CFM and they use a misleading metric no one else uses, kind of scummy for such a quality product. But this thing is SILENT. I had similarly powerful fans on my cpu and they were loud! These are amazing replacements for my heatsink's stock fans. I absolutely love these fans and will be buying more for the rest of my case eventually.
Summary: Expensive... but it comes with ALL the bells and whistles. You get an extension cord, a cord for low rpm, a y-splitter, rubber pads everywhere. Also it's quiet. Replaced the Cooler Master fan that comes in a Hyper212 which was already not noisy. I barely notice my computer is on under my desk. Also this matched airflow (temperature measured) with the CM fan at the lower RPM, so no need for more noise!
Perfect as a fan replacement for Corsair H60 liquid cooler fan (not the actual liquid cooler!)

Summary: The 120mm stock fan that comes with the H60 is extremely loud. I used that stock fan inside a Hackintosh build, for a 3930k i7, LGA2011, mainly for video editing (with Mavericks OSX). Even though I use headphones most of the time for foley/sound editing, the Corsair stock fan was so loud that I eventually broke down and researched what alternatives were available. Comes the Noctua NF-F12 PWM. Now, a lot of reviews from the self proposed geek experts are misleading.
