As is known, sources of noise from the fans is not only the work of blades on the air movement, but also created at the same time with the vibration transmitted to the chassis or heatsink.  Nanoxia company has found a way to solve this problem, and introduced a new line of fans Special NNV, a key feature of which is, according to the manufacturer, the complete absence of vibration during operation.
In order to prevent vibration from the fan to be transmitted to the chassis or heatsink in fans Special NNV used  double border. Â
Total to date in the series Special NNV four 120-mm fan was presented, which differ in rotation speed and noise. Â Model Special NNV 120 - PWM, as you might guess from the name, version supports PWM speed control. Â Its blades can rotate at a speed of 400 to 1650 r / min, thus creating the air flow to 52.6 CFM (89,4 m³ / h). Â The maximum noise level of 24.6 dBA.
Special NNV fans 120 in turn with prefixes 800, 1200 and 2000 have a fixed rotational speed and the actual component 800, 1200 and 2000 rev / min, respectively. Â Slowest model capable of creating air flow in 27.2 CFM (46,2 m³ / h), while the noise level of only 6.1 dB. Â Average novelty provides 44.7 CFM (75,9 m³ / h) with a noise level of 17.7 dBA. Â Finally, the fastest of the submitted fan provides air flow to 73.0 CFM (124 m³ / h).
Fan Special NNV 120 - PWM will be available in mid-February, and the rest of the model a few weeks later. Â The cost of new products will be 22 euros. Related Products :
