Zalman rolled out the ZM-F4, a 135 mm case fan that features a 120 mm compatible frame that lets it fit into most 120 mm case fan mounts and CPU heatsinks. Capable of 900 to 1,300 RPM rotational speeds, the ZM-F4 has rated noise levels of 18 to 26 dBA. The advanced sleeve bearing is said to ensure a life-span of 50,000 hours. The fan uses standard 3-pin power input, a bundled resistor cable keeps the fan down to its minimum speed ensuring low noise output. Zalman also opted for rubber pins instead of metal screws to bundle with its fan. Pricing and availability is not known.
