Noctua has introduced three fans from its A-series, aimed at users who are looking for quiet cooling. The fans will be available in sizes of 40mm, 60mm, and 92mm and will have model numbers NF-A4x10, NF-A6x25, and NF-A9x14. The company was able to achieve the audible performance of these fans by reducing the motor hub size of the fans and by using Flow Acceleration Channels, which alter the shape of the fan blades. The 92mm fan is only 14mm thick and will also be an excellent choice in applications like HTPCs where space is at a premium. The fans will cost $15.90, $17.90, and $19.90 for the 40mm, 60mm, and 92mm fans, respectively.
