The Sealed Precision FDB bearing used ensures a long service life of over 120,000 hours. Decouplers installed in the corners reduce vibrations and thus contribute to the extremely low noise level of the fan. The features of the Scythe Kaze Flex 140 Square PWM fan: Powerful PWM fan in black Very smooth running and long service life thanks to Precision FDB bearings Decouplers attached to the fan frame for vibration reduction With ARGB lighting (4-pin) Speed range up to 1,200 rpm. Whisper-quiet operation at max. 19.4 dB (A) 4-pin connector, 30 cm long sleeved cable Versatile fan: Scythe Kaze Flex 140 Square ARGB PWM In order to guarantee a high level of smoothness and durability, the fans from the Kaze Flex series use a self-contained liquid store (Sealed Precision FDB). This drastically reduces friction and thus ensures suppleness and reduced wear, which results in an average service life of 120,000 hours. The special rotor design ensures a high contact pressure of up to 1.25 mmH2O and also delivers a delivery volume of a maximum of 114.2 m3 / h. Despite its good cooling performance, the Scythe Kaze Flex 140 Square ARGB is barely audible at only 19.4 dB (A), even under full load. Quiet operation and ARGB lighting The Kaze Flex 140 Square ARGB fan is equipped with vibration and shock absorbing rubber pads on the screw holes. These decouplers effectively prevent the transmission of vibrations and contribute to low-noise operation. A 30 cm long sleeved connection cable enables installation in almost any system. A 50 cm extension cable is included in the scope of delivery. The cable for the ARGB lighting is 30 cm long and equipped with a 4-pin plug and a 4-pin socket.
