Kaze Flex 120 Silm PWM KF1215FD18-P Features: The bearing structure of FDB (Fluid Dynamic Bearing) is made of high quality compressed metal, which contributes to low friction and a long life span. High quality lubricant oil enclosed between the shaft and bearing withstands temperatures of up to 250°C and results in an excellent lubricating effect. Vibration and shock absorbing rubber pads are integrated into the fan's design and further enhance a silent operation, making this fan ideal for cases and coolers.
