Sealed Precision FDB reduces friction, ensuring smooth operation and reduced wear, which results in an average life-span of 120 000 hours. Included vibration- and shock absorbing rubber pads which cover the tunnelless mounting holes. These decouplers effectively eliminate possible vibrations and allow low-noise operation. High airflow with low noise contribution as case fan or CPU cooler fan. The 4-pin RGB connector allows users to choose from a wide range of colors and lightning modes through a RGB-enabled motherboard. 120x120x25mm, 4-pin PWM 300~1200rpm, MTTF: 120,000hrs
