ARCTIC P14 Pro PST Black (ACFAN00314A)

A relatively affordable 140 mm fan designed to deliver high efficiency in confined spaces. The key metric is the high static pressure of 5.2 mm H2O, which allows it to push air through dense radiator fins of liquid-cooling systems or thick dust-filter meshes with minimal performance loss. The wide PWM speed control range from 400 to 2500 RPM provides tuning flexibility: from virtually silent operation under low loads to a maximum airflow of 110 CFM for intensive cooling.

A distinguishing feature of the model is support for PST (PWM Sharing Technology), which allows multiple fans to be daisy-chained to a single motherboard header. This significantly simplifies cable management in the case and ensures synchronized speed control for the entire group. Smooth operation and low vibration are achieved thanks to a hydrodynamic bearing and automatic dual-plane impeller balancing, while a modern motor microcontroller further reduces operating noise.
