This is a new generation top-class fan, 140mm in diameter, which is designed for cooling a computer case. Blade speeds reach a speed of 1200RPM, using L.N.A.. The speed can be reduced to 1050RPM or even to 900RPM by using the U.L.N.A. adapter. The speed is controlled by Smooth Commutation Drive (SCD) technology which provides fully automatic, silent operation and very low power consumption. The air flow is increased by channels at the end of the blades.
The resultant air flow rate is 115.5m3/h at full speed and 101.9m3/h using a L.N.A. or 88.7m3/h using an U.L.N.A. The noise level can be influenced by the speed setting - it is 19.2dB at maximum speed and 16.4dB at reduced speed and only 13.8dB by using the U.L.N.A. Anti-vibration pads in the frame of the product help to reduce the fan noise.
The size of the model is 140 x 140 x 25mm. The motherboard is connected via a 4-pin fan connector. The product uses SSO2 ball bearings with MTBF up to 150,000 hours.
