Zalman, a highly-acclaimed designer of miscellaneous hardware pieces, has elaborated three completely new series of low-noise fans: ZM-FDB(SF), ZM-LED(SF) and ZM-Plus(SF). The ‘triple’ embraces the models of 80 mm, 92 mm and 120 mm dimensions. The fans do not support PWM technology, thus feature a stable rotational speed. The most peculiar feature is low noise level (not more than 23 dB), despite the range of speed.
Zalman ZM-FDB(SF) are characterized by the implementation of high-quality fluid-dynamic bearings. Their lifespan is estimated as 150.000 hours. The other two fan series – Zalman ZM-LED(SF) and Zalman ZM-Plus(SF) — involve long-life bearings, which are thought to be quite reliable and effective. Their framework features dust-repelling mechanisms and this promotes for the elongated lifespan.
Certainly, the ‘triple’ enjoys similar features. For instance, all the fans employ an original Shark Fin blades design. It allows for the decrease of airflow …
