Noctua, although their colors are not appreciated by all, and I see it, but frankly all the fans that I have tried or have, they are by far the best in relation ventilation / silence. The NF-P12 are for a watercooling to replace your origins fans. Although this is not their primary function, I put them in housing ventilation, and they do the job perfectly, while I have a big GTX 780 SLI configuration, i7 4970K. Enjoy the anti-vibration mounting rings, they really aspire, and all in absolute silence, as I did in my noctua turn 7 fans including 4 NF-P12.
You want power in silence, the quiet strength is Noctua, buy eyes closed.
