P12 Silent Pressure-optimised Extra Quiet 120 mm Fan Optimised for Static Pressure During the development of the new P12 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 P12 Silent is particularly suitable for use on heatsinks and radiators. Strong Cooling. Performance Numerous improvements, such as an updated engine technology and a newly developed fan design, have noticeably increased the performance of P-fans. In internal performance tests leveled to 28 dB (A), the new P-fans left many competitors behind. 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.
