The Kaze Flex fan series , already used in the Mugen 5 and praised by testers, is now available separately. Again, a ensures Sealed Precision FDB bearings for a lifetime of over 120,000 hours . Decouplers installed in the corners reduce vibrations and thus contribute to low acoustic emissions. The Kaze Flex 120 Slim PWM offers the choice between a well-balanced speed range or an absolute low-noise solution.The features of the Scythe Kaze Flex 140 PWM fan:- Very smooth running and long service life thanks to Precision FDB bearings- Decouplers attached to the fan frame to reduce vibrations- PWM control, 300 - 1,200 rpm speed at max. 19.4 dB (A)- 28.5 - 114.3 m / h (16.77 - 67.27 cfm) airflow & 1.25 mmH2O air pressure & 12 V operating voltage- 4-pin connector, 30 cm long sleeved cableVersatile fan with innovative features: the Scythe Kaze Flex 140 PWMIn order to guarantee smooth running and a long service life, the fans from the Kaze Flex series use a self-contained liquid store (Sealed Precision FDB). The bearing and the spindle are made entirely of high-quality, compressed metal and are lubricated by a special oil film that is persistent up to a temperature of 250 C . This drastically reduces friction and thus ensures flexibility and reduced wear, which results in an average service life of 120,000 hours .The Kaze Flex fan was made with vibration and shock absorbing rubber padsfitted to the tunnelless screw holes. These decouplers effectively prevent the transmission of any vibrations that may occur and contribute to low-noise operation. A generously dimensioned and sleeved connection cable of 30 centimeters enables installation in almost every system. A 50 cm extension cable is included with the fan.Technical details:- Dimensions: 140 x 140 x 27 mm (W x H x D)- Weight: 150 g- Material: Plastic- Colour: Black (frame), gray (rotor, decoupler)- Connection fan: 4-pin PWM- Cable length: 300 mm (sleeved)- Speed: 300 to 1,200 rpm- Volume: 4.19 to 19.4 dB (A)- Delivery volume: 28.4 to 114.3 m / h (16.77 - 67.27 cfm) - Static pressure: 0.08 to 1.25 mmH2O- Power consumption: 1.44 W- Voltage: 12V- Life expectancy: 120,000 h (MTBF)Contents:- 1x fan- 4x fan screws- 1x extension cable (500 mm, sleeved)Manufacturer\'s guarantee: 1 year
