There once was a product on Noctua roadmap of upcoming products, it was called the desk fan. It was always a year or more out however, it never came to market. The newest Noctua roadmap of upcoming products doesn't even list it anymore. Some time ago I made one of these mythical Noctua Desk fans and it worked really well, So well I thought what if Noctua did the same thing but to a 16 inch stand fan.
