While it is important to be outstanding on paper, practical excellence is what that keeps you going in the long run. Take cars, for example. Yes, I will admit most of us here are not exactly the biggest fans of Hyundai and Kia, and we do frequently take jabs at their products, but the reason is because we have actually test driven them in an objective manner. We were not paid to say anything good about them, nor were we swayed by all the irrational praise by many automotive media outlets. The point is, while it looks like you are getting a lot of car for the money simply by reading the specifications sheet, it does not really mean you are getting a lot of car for the money. Stuff like a rough, gutless engine, poorly programmed transmission, wipers that don't work very well, uncomfortable seats, and real world fuel economy that is nothing like EPA ratings are just a few things I can name right off my head that you can't determine by looking at the window sticker. In the same way, here at APH Networks, we have always been huge proponents of Noctua fans -- not because they have the highest CFM rating or lowest dB values on paper, but because they provide most competitive airflow at the lowest amount of perceivable noise in real life. You know, more like the big H rather than the slanted H of the computer cooling world. How well does the Noctua NF-P12 PWM and Noctua NF-F12 PWM live up to the legacy set by its predecessors? To find out, we took three of each in, and put them to the tests.
