b flow acceleration channels b br br the nf a4x10 impeller features suction side flow acceleration channels . by speeding up the airflow at the crucial outer blade regions this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise . br br br br b reduced motor hub size b br br thanks to its streamlined compact motor design the nf a4x10s motor hub is smaller than with conventional 4cm fans . this allows for more blade surface area and thus contributes to the nf a4x10s superior airflow and pressure performance . br br br br b aao frame b br br noctuas aao advanced acoustic optimisation frames feature integrated anti vibration pads as well as noctuas proprietary stepped inlet design and inner surface microstructures both of which further refine the fans performance noise efficiency . br br br br b stepped inlet design b br br noctuas stepped inlet design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow which reduces tonal intake noise improves flow attachment and increases suction capacity especially in space restricted environments . br br br br b inner surface microstructures b br br with the tips of the fan blades ploughing through the boundary layer created by the inner surface microstructures flow separation from the suction side of the blades is significantly suppressed which results in reduced blade passing noise and improved airflow and pressure efficiency b size b br 40x40x10 mm br br b connector b br 3 pin br br b bearing b br sso2 br br b blade geometry b br a series with flow acceleration channels b frame technology b br aao advanced acoustic optimisation br br b rotational speed 10 % b br 4500 rpm br br b rotational speed with l.n.a. 10 % b br 3700 rpm br br b airflow b br 82 m h b airflow with l.n.a. b br 66 m h br br b acoustical noise b br 179 db a br br b acoustical noise with l.n.a. b br 129 db a br br b static pressure b br 178 mm h2o br br b static pressure with l.n.a. b br 121 mm h2o b max . input power b br 06 w br br b max . input current b br 005 a br br b voltage b br 12 v br br b mtbf b br 150.000 h b scope of delivery b br low noise adaptor l.n.a. br 3 2 pin adaptor br omnijoin adaptor set br 30cm extension cable br 4 vibration compensators br 4 fan screws b item dimension lxwxh b br 8.5 x 6 x 1.5 br br b weight b br 0.5 lb br br b warranty information b br 6 years
