This extremely quiet fan is designed to improve the air circulation in the computer case. Its dimensions are 120 x 120 x 25mm. It is sure to please especially those who appreciate silence. The specially designed rotor blades ensure the quietest operation. The normal fan speed is 1200rmp. This can, however, be reduced to 900rpm by the LNA (Low-Noise-Adapter) adapter or to 700rpm by the ULNA (Ultra-Low-Noise Adapter) adapter. This will reduce the noise level to mere 7.4dB. This fan is, therefore, the ideal solution for noise reduction. Included is the 3-pin connector, LNA adapter, screws and vibration dampers.

FAN ... in this case there is no place for compromise. Noctua is simply a diamond are among stones. My advice, if you want good cooling, not want to find elsewhere. Now I have this fan dressed the source (Corsair VX 450) and the difference is unspeakable. I began to test FarCry4 in fullHD at ultra settings ... so stock Fano I had a feeling that my fighter gets off. Now that was as old fan in idle Noctua is behaving in a full load. 0
