Zalman presents the ZM-Fx-FDB, a new series of case fans available in 80mm, 92mm and 120mm sizes. These fans use a low-noise fluid-dynamic bearing (FDB) that promises a MTBF of 150,000 hours and the fan features PWM-based speed control. Zalman includes silicon mounting pins to reduce vibrational noise, and it your fan needs to be even more silent you can use an included resistor to enable low-noise speed mode.
The ZM-F1-FDB spins at 1,400~2,000 rpm with 18~23 dBA noise output, ZM-F2-FDB at 1,300~2,000 rpm with the same 18~23 dBA noise, and ZM-F3-FDB at 1,000~1,500 with 18~23 dBA noise as well. With the ZM-RC56 resistor in place, the fans spin at a lower speed, with a constant noise output of 18 dBA. While the ZM-F2-FDB is due for market release on the 25th of September, the ZM-F1-FDB is priced at 7.9 EUR, and ZM-F3-FDB at 9.5 EUR.
