Zalman has started shipping its newest low-noise case fans, the ZM-Fx-FDB series (where "x" is 1,2,3, representing 80 mm, 92 mm, 120 mm, respectively). The fan uses three means to lower noise output: a PWM-based speed control, silicone pins that attach it to the case instead of metal screws, and fluid-dynamic bearing (FDB) that has a long life and makes low noise. The FDB ensures the fan has a service life of 150,000 hours. The impeller is made of translucent (frost) plastic, though it isn't LED-lit. A low-noise speed mode can be selected by placing the provided resistor.

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.
