Pressure-optimised 120 mm Fan Value Pack (5 Fans) Optimised for Static PressureDuring the development of the new P12, 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 P12 is particularly suitable for use on heatsinks and radiators. High Quality BearingThanks 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.
