The premium quality of the Japanese double ball bearing allows for continuous operation 24/7 without compromising performance. Contamination and high temperatures make this bearing much less of a problem than ordinary plain or ball bearings. Therefore, the double ball bearing is the perfect choice if you want to ensure continuous operation. In the development of the new P14 PWM PST CO, particular emphasis was placed on a focused air flow and high static pressure. The fan thus guarantees extremely efficient cooling, even with increased air resistance. The P14 PWM PST CO is therefore particularly suitable for use with heat sinks, radiators, pinholes and filters.
