Arctic P14 Pro PST Black (ACFAN00314A)

The Arctic P14 Pro PST is a 140-mm fan with PWM control and PST technology that allows multiple fans to be connected in series to a single control signal. The fan is designed for cases with 140-mm mounting locations, liquid coolers, mesh panels, dust filters, and other areas where both airflow and the ability to push air through resistance are important. The unit measures 140 x 140 x 27 mm and weighs 242 g, so installation requires consideration not only of the diameter but also the increased thickness compared to typical 25-mm models. The operating range is 400–2500 rpm with the ability to shut down completely below 5% PWM signal. Maximum airflow is rated at 110 CFM or 186 m³/h, and static pressure is 5.2 mm H2O, making this model suitable for high-performance yet noise-controlled cooling systems. The design features a hydrodynamic bearing, optimized rotor, minimal clearances, and automatic dual-plane balancing to reduce vibration. Connection is via 4-pin Fan Plug and 4-pin Socket, and the 400-mm cable with an additional 80-mm PST branch simplifies installation of multiple fans in a case.
