Pressure-optimised Extra Quiet 80 mm Fan Optimised for Static Pressure During the development of the new P8 Silent, special emphasis was placed on a focused airstream and thus a high static pressure. The fan guarantees extremely efficient cooling, even with increased air resistance. Therefore, the P8 Silent is particularly suitable for use on heatsinks and radiators. High Quality Bearing Thanks to an alloy/lubricant combination developed in Germany, friction within the bearing is reduced and greater efficiency is achieved. As a result, there is less heat development as well as less bearing noise, which means you can enjoy a longer service life from your fan. Virtually Silent Motor At low fan speed, the motor is the main source of unwanted noise. A motor developed in Germany with an enhanced bearing reduces friction and noise.
